An irregular heartbeat is usually not a cause for concern. However, if your symptoms persist, keep coming back, or if you develop chest pain, lightheadedness, or difficulty breathing, you should seek medical attention.
You should also seek treatment if you experience an irregular heartbeat with:
- Diabetes
- High blood pressure.
- Coronary artery disease
- Congestive heart failure
- Hyperthyroidism
- Family history of heart disease
What causes an irregular heartbeat?
The sinoatrial node in the heart transmits electrical signals that cause the heart muscles to contract and produce a regular heartbeat. Disruption in the transmission of these signals can cause an irregular heartbeat, also known as arrhythmia. Moreover, you may feel as if there are extra beats in between when you experience tachycardia.
Most arrhythmias are short-lived and may caused by the following:
- Too much caffeine
- Excessive alcohol intake
- Vigorous exercising
- Dehydration
- Illegal drug use such as cocaine or ecstasy
- Fever
- Anemia
- Emotional distress
- Sleep apnea
- Pregnancy
What tests are used to diagnose an irregular heartbeat?
If you frequently have irregular heartbeats, one or more of the tests may be ordered:
- Echocardiogram: Involves the use of high-frequency sound waves from a hand-held wand placed on your chest. It provides pictures of the valves and chambers of the heart and helps the sonographer evaluate the pumping action of the heart.
- Exercise stress test: Requires you to run on a treadmill while the machine records the response of your heart.
- Holter monitoring: Requires wearing a portable device known as a holter monitor that records electrical activity and heartbeats for 24-48 hours.
- Genetic heart testing: Checks whether irregular heartbeats are due to an inherited heart condition.
Your doctor may perform testing to rule out underlying conditions and prescribe medications to protect your heart health.
How to maintain a healthy heart with irregular heartbeats
- Monitor your caffeine intake: If you have an irregular heartbeat after drinking caffeinated drinks such as coffee, keep an eye on how many cups you drink.
- Limit your alcohol intake: If your condition is caused by excessive alcohol consumption, restrict yourself to no more 1-2 drinks a night. If you have had a heart attack in the past or have atrial fibrillation, you should avoid even moderate drinking.
- Lose weight: Obesity and being overweight can increase your risk of irregular heartbeats. However, while losing weight can help, avoid diet plans or pills that promise rapid weight loss because they can increase your risk of complications.
- Get adequate sleep: Getting enough sleep—6-8 hours a night—helps lower your stress levels and reduce fatigue, both of which can trigger irregular heartbeats.

adenosine
Adenosine is an antidysrhythmic drug used to treat a type of irregular heart rhythm disorder known as paroxysmal supraventricular tachycardia (PSVT). Common side effects of adenosine include flushing, chest pressure and discomfort, shortness of breath (dyspnea), headache, throat, neck and jaw discomfort, gastrointestinal discomfort, lightheadedness, dizziness, upper extremity discomfort, electrical disturbances in the heart, abnormal ECG readings, low blood pressure (hypotension), numbness and tingling (paresthesia), irregular heart rhythms (arrhythmia), and nausea. Consult your doctor before taking if pregnant or breastfeeding.
Angina: Signs, Symptoms, and What It Feels Like
Angina is chest pain due to inadequate blood supply to the heart. Angina symptoms may include chest tightness, burning, squeezing, and aching. Coronary artery disease is the main cause of angina but there are other causes. Angina is diagnosed by taking the patient's medical history and performing tests such as an electrocardiogram (EKG), blood test, stress test, echocardiogram, cardiac CT scan, and heart catheterization. Treatment of angina usually includes lifestyle modification, medication, and sometimes, surgery. The risk of angina can be reduced by following a heart healthy lifestyle.Camzyos (mavacamten)
Camzyos (mavacamten) is a prescription medication used to treat the symptoms of obstructive hypertrophic cardiomyopathy (HCM). Camzyos reduces left ventricular ejection fraction (LVEF) and can cause heart failure due to systolic dysfunction. Camzyos may cause serious side effects including hives, difficulty breathing, swelling of your face/lips/tongue/throat, fainting, and reduced left ventricular ejection fraction from the heart. Consult your doctor before taking Camzyos if pregnant or breastfeeding.

Heart Palpitations: 14 Possible Causes and Should You Worry?
Heart palpitations are caused by stress, exercise, caffeine, nicotine, hormone changes, fever, medications, low blood sugar, overactive thyroid, heart rhythm problems, alcohol, PVCs, and illegal drugs. Doctors may use tests like an ECG, Holter monitor, event monitor, and electrocardiogram to help diagnose the underlying cause of heart palpitations.
Arrhythmias (Abnormal Heart Rhythms): Types, Triggers, Warning Signs, and Treatment
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.lemon balm
Lemon balm has been used traditionally for centuries as a medicinal herb to promote sleep, relieve stress and anxiety, improve appetite and digestion, and to treat viral and other infections. The suggested uses of lemon balm include insomnia, anxiety, improving cognitive function, irregular heart rhythm and nervous palpitations, high blood pressure (hypertension), antispasmodic, appetite stimulant, indigestion, menstrual irregularities, and others. Common side effects of lemon balm include nausea, dizziness, sedation, increased appetite, wheezing, hypersensitivity reactions, and skin irritation.
Is It Normal to Have Irregular Heartbeat After Ablation?
Cardiac (heart) ablation is a procedure performed to correct heart arrhythmias (irregular heart rhythm/beat). Cardiac ablation works by intentionally injuring or destroying (ablating) and scarring the tissue in the heart that triggers the abnormal heart rhythm.

Take the Sudden Cardiac Arrest Quiz. Learning about this potentially deadly condition may save a life.
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.
What Is a Good Resting Heart Rate by Age and Gender?
Normal resting heart rate (RHR) values can range from anywhere between 60-100 beats per minute (bpm). As cardiovascular fitness increases, the resting heart rate value decreases. Resting heart rate is the number of beats per minute the heart takes while a person is fully rested.
