Wearable Cardioverter-Defibrillators

摘要: Since its introduction >3 decades ago, the implantable cardioverter-defibrillator (ICD) has been used extensively to enhance survival of patients at high risk for sudden cardiac death resulting from life-threatening ventricular tachyarrhythmias (VTs; ie, sustained VT and fibrillation [VF]).1,2 Nevertheless, invasive nature implantation procedure, cost issues, potential complications related an in-dwelling intravascular device (eg, inappropriate shocks, infection, thrombosis) have limited use ICD therapy whose is considered be both very permanent. Consequently, undergoing diagnostic workups underlying causes VT/VF or those with reversible frequently remain unprotected against arrest time periods variable duration. Similarly, awaiting contraindications may also go significant periods. The recent emergence wearable provides a new prophylactic strategy who are but not immediate candidates implantation. patient population likely derive most benefit defibrillator remains defined.
