What does the future hold for ICDs?
Implantable defibrillator technology continues to improve. The size of ICDs has decreased dramatically which makes the ICD easier to implant, less visible, and more comfortable. Other advances include not only technology improvements, but clinical trials that may expand the indications and uses for this exciting lifesaving device.
