The answer is: Arrhythmias.
Explanation:
Implantable cardioverter defibrillator: It is a device that detects any rapid and life-threatening heartbeat. Said abnormal heartbeat is called arrhythmia.

Arrhythmias: It is a disorder of heart rate, pulse, or heart rate. The heart may beat too fast, tachycardia, too slow, bradycardia, or irregularly.
