Seniors who receive an implantable cardioverter defibrillator (ICD) have high survival rates, a new study finds.
An ICD — which is placed under the skin and connected to the heart with wires — detects an irregular heartbeat and delivers an electrical shock to restore normal rhythm.
In the study, researchers analyzed data from more than 12,400 Medicare patients, aged 65 and older, who received an ICD after sudden cardiac arrest or a nearly fatal fast heart rhythm.
