- An electrical system controls the muscle cells and rhythmic pumping motion of your heart, which establishes and regulates the heart rhythm and maintains your heartbeat constant.
- However, the electrical system may occasionally become abnormal, causing the heart to beat irregularly, slower or faster, or in irregular patterns, and it can even cease beating entirely due to certain pathologies.
- In ventricular fibrillation, the two lower chambers of the heart, known as the ventricles, appear to be out of control, causing the heart's rhythm to vary abruptly.
- This might possibly result in rapid cardiac death.
- This starts when the sinoatrial node fails to send out proper electrical impulses.
- When the electrical impulse enters atrial fibrillation, the ventricles are unable to adequately pump blood out to the body.
What causes cardiac arrest in younger people?
The most common causes of cardiac arrest vary with age. The majority of deaths in adults older than 35 years are caused by coronary artery disease. There is no single primary cause of cardiac arrest among people younger than 35 years.
Some of the disorders that might cause cardiac arrest in young individuals include:
- Hypertrophic cardiomyopathy: A condition in which the heart muscle becomes too thick
- Long QT syndrome: A condition that can cause a dangerously erratic heartbeat
- Brugada syndrome: A heart rhythm disorder
However, 40 percent of sudden cardiac deaths in young people remain unexplained even after autopsy.
4 conditions that increase your risk of sudden cardiac arrest
The following are the most frequent conditions that increase your risk of sudden cardiac arrest (SCA):
- Coronary artery disease:
- Congenital heart disease:
- Every year, an estimated one percent of newborns in the United States are born with cardiac problems, some of which are recognized early on, whereas others go unnoticed.
- Long-QT syndrome, arrhythmogenic right ventricular cardiomyopathy, and hypertrophic cardiomyopathy are a few examples.
- These cardiac disorders can produce changes in the electrical system of the heart or changes in the heart muscle that can affect the electrical system of the heart.
- One of the main reasons why doctors listen to your heartbeat during a physical exam is to detect these heart problems.
- Structural changes in the heart:
- Family history of cardiac arrest:
- If someone in your family has died from a heart attack, your risk increases dramatically.
Risk factors for cardiac arrest
Cardiac arrest can be caused by various factors. Certain variables, however, put you in danger of an SCA. Understanding and monitoring these circumstances might help you avoid this condition.
Fourteen variables that put you at risk of a cardiac arrest include:
- High blood cholesterol
- Heavy consumption of alcohol
- No physical activity
- A family history of coronary artery disease
- A previous heart attack
- An episode of cardiac arrest in the family
- Consuming illegal drugs such as amphetamines and cocaine
- Having heart conditions such as birth defects and cardiomyopathy
- Not getting enough nutrition
- Elderly age
Cardiac arrest occurs when the heart stops pumping blood. If quick action to revive the heart is not done, the person may die.
Cardiac arrest can occur for other reasons, including:
- Major blood loss or severe lack of oxygen
- Intense exercise if you have heart problems
- Too high levels of potassium or magnesium could lead to a deadly heart rhythm
- Your genes; you may inherit certain arrhythmias or a tendency to get them
- Changes in your heart's structure, for instance, an enlarged heart or changes caused by an infection

12 common signs and symptoms of a cardiac arrest
Certain indications and symptoms of a cardiac arrest might be termed “warning signals.” If you or someone close to you develops any of the following symptoms, contact 911 immediately.
Twelve signs and symptoms of cardiac arrest include:
- Extreme dizziness
- Shortness of breath
- Possible uneasiness in the chest
- Chest congestion that can get worse with time
- Heart palpitations
- No pulse
- Difficulty breathing
- Lose consciousness
- Feel nauseous or have an urge to vomit
Every year, between 300,000 and 400,000 people suffer from cardiac arrest. Only if therapy is administered soon is it possible to survive a cardiac arrest without long-term consequences. Delays might cause brain damage or even death.Cardiovascular arrest is currently one of the main causes of mortality in the United States.
What are the immediate treatment for a cardiac arrest?
A cardiac arrest must be treated as soon as possible, within minutes, or the person will suffer serious brain damage and die. The immediate objective is to get the heart to start beating again.
Automated external defibrillator (AED)
- The most successful method is to use an AED, which efficiently restarts the heart by giving electrical energy to it.
- Anyone may use this equipment to deliver an electric pulse or shock to the heart. AEDs can be located in various public places. (Follow the instructions on it before proceeding.)
Cardiopulmonary resuscitation (CPR)
- CPR can be performed to restore the heartbeat by pumping blood to essential organs.
- People who have received CPR training can considerably enhance their chances of surviving a cardiac arrest by performing mouth-to-mouth breathing and chest compressions.
- Everyone is encouraged to learn hands-only CPR, according to the American Heart Association.
- CPR performed while waiting for emergency responders has the potential to save a life.
According to the American Heart Association, anybody who has not been taught may conduct hands-only CPR, which is a two-step process:
- Call 9-1-1 or delegate the call to someone else.
- Push strongly and quickly in the middle of your chest.
What is the long-term treatment for a cardiac arrest?
People who survive cardiac arrest must go through a series of treatments to address any underlying problems. These procedures often comprise the following:
- Coronary angioplasty:
- If a cardiac arrest was caused by clogged coronary arteries, doctors prescribe coronary angioplasty, a minimally invasive surgery that uses a balloon catheter to open a clogged artery.
- It helps resume normal blood flow to the heart.
- Coronary bypass surgery:
- It is the preferred technique for people with severe coronary artery disease.
- By bypassing the blocked artery, it restores blood flow to the heart muscle. Traditional open surgery or less-invasive procedures can be used to execute the treatment.
- Corrective heart surgery:
- Congenital heart abnormalities that enhance the person’s risk of cardiac arrest are repaired or treated.
- Structure problems in the heart can affect the valves inside the heart, internal walls of the heart, and veins and arteries that deliver blood to the body or the heart.
- Radiofrequency catheter ablation:
- It works by damaging cardiac tissue that causes irregular heart rhythms. People can avoid arrhythmia, which can lead to cardiac arrest, by preventing aberrant electrical signals from entering the heart.
Death can ensue within minutes unless an emergency shock is administered to the heart to restore its normal rhythm using equipment known as a defibrillator. More than 70 percent of people with ventricular fibrillation die before reaching the hospital.
Cardiac arrest is considered a medical emergency.
How is cardiac arrest monitored?
People must be admitted to the hospital after resuscitation to be monitored by medical personnel.
To determine what caused the cardiac arrest, diagnostic procedures such as electrocardiography, blood pressure monitors, and others will be performed. The person will be continuously observed and cared for until the reason is identified, and a treatment plan will be implemented.
Once the person is stable, doctors recommend that a cardioverter defibrillator, or an implantable cardioverter defibrillator (ICD), be implanted to reduce the person’s chance of experiencing another cardiac arrest in the future.
- ICD is a tiny device that is placed in the chest or abdomen.
- It is made up of cables with electrodes that attach to the heart chambers and monitors the heartbeat.
- If it detects any irregularities, it sends a regulated burst of impulses to the heart to stabilize the beat.
- ICD implant surgery is a standard operation that may be done under general anesthesia. During surgery, insulated wires are put into veins near the collarbone and threaded to the heart with the use of imaging equipment.
- Leads are then anchored to the heart, and other ends are connected to the generator, which is implanted just beneath the skin of the collarbone.

Can a person survive sudden cardiac arrest?
Sudden cardiac arrest (SCA) occurs when the heart stops beating suddenly owing to an arrhythmia. People who have experienced a past heart attack or have coronary artery disease are more likely to experience this. It is critical to understand your risk factors for SCA, such as whether you have a cardiac problem or a family history of SCA.
According to the American Heart Association, just 11 percent of people who have SCA live to be discharged from the hospital. After SCA, your chances of survival increase if you do the following:
- The time elapsed between cardiac arrest and cardiopulmonary resuscitation (CPR) is extremely brief. Instantaneous CPR increases the likelihood of survival by doubling or tripling it.
- Survivors of SCA are more likely to experience neurological, psychosocial, and other health problems. If you or someone you care about has survived a cardiac arrest, there are resources to cope with the challenges that may occur as a result of the experience.
The prognosis for people with cardiac arrest is typically bad, with more than 9 out of 10 people dying before or during emergency medical care. Meanwhile, some of those who survive are in a permanent vegetative state or have brain damage and limited consciousness.
How can you prevent a cardiac arrest?
A cardiac arrest can occur due to various circumstances. Factors may differ from one individual to the next. Knowing the signs and symptoms of a cardiac arrest might help you lower your chances of having one.
- To avoid this disease, you should have frequent checkups and tests for cardiac abnormalities.
- To preserve heart health, you must adopt and encourage some healthy behaviors, such as:
- People who have or have had various cardiac diseases in the past should visit a doctor to enhance their health, which may entail:
- Following a nutritious diet
- Taking medications on time
- Engaging in physical activity.
In the majority of instances, warning indicators are there beforehand, but they are frequently misinterpreted or ignored. Knowing the signs of cardiac arrest and heart problems, as well as knowing how to avoid them, can help you save yourself

Can You Have Sex Right After a Heart Attack?It is important not to put any pressure on yourself or your heart after heart attack. Initially, you might feel less interested in sex. That is perfectly normal, and the feeling goes away quickly.
Heart Attack PreventionHeart disease and heart attacks can be prevented by leading a healthy lifestyle with diet, exercise, and stress management. Symptoms of heart attack in men and women include chest discomfort and pain in the shoulder, neck, jaw, stomach, or back.
Heart Attack Prevention OverviewHeart attacks are the major causes of unexpected, sudden death among men and women. A heart attack also is a significant cause of heart failure. The process of developing atherosclerosis (hardening of the arteries) begins early in life. Heart attack prevention should begin in childhood because the atherosclerosis process can not be reversed. The risk of having a heart attack increases if you have diseases or conditions such as high blood pressure, diabetes, and other heart conditions.
Heart Attack Treatment
A heart attack involves damage or death of part of the heart muscle due to a blood clot. The aim of heart attack treatment is to prevent or stop this damage to the heart muscle. Heart attack treatments included medications, procedures, and surgeries to protect the heart muscle against injury.
Heart Attack vs. Stroke Symptoms, Differences, and Similarities
Heart attack usually is caused by a clot that stops blood flow supplying oxygen to an area of heart muscle, which results in heart muscle death. Stroke or "brain attack" is caused by a loss of blood supply to the brain (usually a blood clot) or by hemorrhagic stroke (bleeding within the brain), which results in brain tissue death. Both heart attack and stroke usually come on suddenly, produce similar symptoms, can be disabling, and can be fatal.
The classic symptoms and warning signs of heart attack are different.
Classic heart attack warning signs are chest pain or discomfort, shortness of breath, pain that radiates to the shoulders, back, arms, belly, jaw, or teeth, sweating, fainting, and nausea and vomiting. Moreover, woman having a heart attack may have additional symptoms like abdominal pain or discomfort, dizziness, clammy skin, and moderate to severe fatigue.
The classic symptoms and warning signs that a person is having a stroke are confusion or loss of consciousness, sudden severe headache, speech problems, problems seeing out of one or both eyes, and numbness or weakness of only one side of the body. Moreover, a woman having a stroke may have additional warning symptom and signs like shortness of breath, disorientation, agitation, behavioral changes, weakness, nausea, vomiting, seizures, and hiccups.
Recognition of stroke symptoms is vital for emergency treatment. The acronym "FAST" stands for recognition of Facial drooping, Arm weakness, Speech difficulty, and a Time for action.
If you experience the symptoms heart attack or stroke (FAST) or see them develop in another person, then contact 911 immediately.
Heart Disease: Causes of a Heart AttackHeart disease prevention includes controlling risk factors like diet, exercise, and stress. Heart disease symptoms in women may differ from men. Use a heart disease risk calculator to determine your heart attack risk.
Am I Having a Heart Attack? Symptoms of Heart DiseaseHeart attacks symptoms vary greatly for men and women, from anxiety and fatigue to nausea and sweating. Learn the warning signs of a heart attack and know the symptoms that may require an immediate trip to the hospital.
Arrhythmias (Heart Rhythm Disorders)Heart rhythm disorders vary from minor palpitations, premature atrial contractions (PACs), premature ventricular contractions (PVCs), sinus tachycardia, and sinus bradycardia, to abnormal heart rhythms such as tachycardia, ventricular fibrillation, ventricular flutter, atrial fibrillation, atrial flutter, paroxysmal supraventricular tachycardia (PSVT), Wolf-Parkinson-White syndrome, brachycardia, or heart blocks. Treatment is dependent upon the type of heart rhythm disorder.
How Long Does It Take to Recover From a Heart Attack?While it takes most people about 6-8 months to recover after a heart attack, overall recovery time depends on your general health, how severe the attack was, the type of treatment you received and when you received it.
Cardiac Arrest QuizTake the Sudden Cardiac Arrest Quiz. Learning about this potentially deadly condition may save a life.
Sudden Cardiac ArrestSudden cardiac arrest is an unexpected, sudden death caused by sudden cardiac arrest (loss of heart function). Causes and risk factors of sudden cardiac arrest include (not inclusive) abnormal heart rhythms (arrhythmias), previous heart attack, coronary artery disease, smoking, high cholesterol,Wolff-Parkinson-White Syndrome, ventricular tachycardia or ventricular fibrillation after a heart attack, congenital heart defects, history of fainting, heart failure, obesity, diabetes, and drug abuse. Treatment of sudden cardiac arrest is an emergency, and action must be taken immediately.
What Happens If Arrhythmia Is Left Untreated?Untreated arrhythmia in some individuals may increase the risk of stroke, heart attack, dementia, and heart failure. It may lead to the inadequate blood supply to multiple organs because the heart may not function properly.
