Quizplus · Accepted Answer

The ICD is designed to detect and treat ventricular tachycardia or fibrillation, as these are the most life-threatening arrhythmias. Atrial arrhythmias, such as atrial fibrillation, are generally not treated with ICD shocks. Arterial and venous arrhythmias are not typically treated with ICDs.
