The risk for sudden cardiac death can be increased among patients with either ischemic or non-ischemic cardiomyopathies with
depressed ejection fractions who may have had a recent myocardial infarction with or without a revascularization procedure.
Arrhythmias are common and can be life-threatening; however, there are misperceptions surrounding the use of implantable cardioverter-defibrillators
(ICDs). Guidelines and reimbursement policies are not always clear, nor in agreement, as to which patients are candidates
for ICDs. The wearable cardioverter-defibrillator is an underappreciated option. Clinicians need to be aware of all patient
populations at high risk for sudden cardiac arrest, including those not meeting current treatment guidelines for ICD implantation,
so proper prevention measures may be taken in order to improve patient survival.
