Answer:
The answer is: Arrhythmias.
Step-by-step explanation:
Implantable cardioverter defibrillator: It is a device that detects any rapid and life-threatening heartbeat. Said abnormal heartbeat is called arrhythmia.
If present, the implantable cardioverter defibrillator (DCI) quickly sends an electric shock to the heart. This changes the rhythm back to normal. This is called defibrillation.
Arrhythmias: It is a disorder of heart rate, pulse, or heart rate. The heart may beat too fast, tachycardia, too slow, bradycardia, or irregularly.
The answer is: Arrhythmias.
