  • Title: Ventricular tachycardia/fibrillation: therapeutic alternatives.
    Author: Fisher JD, Kim SG, Roth JA, Ferrick KJ, Brodman RF, Gross JN, Furman S.
    Journal: Pacing Clin Electrophysiol; 1991 Feb; 14(2 Pt 2):370-5. PubMed ID: 1706855.
    Abstract:
    It is now clear that no single therapy is appropriate for a consecutive series of patients with ventricular tachycardia or ventricular fibrillation (VT/VF). Drug responders by electrophysiological studies, patients who are not inducible following surgery, and patients treated with an implantable cardioverter defibrillator (ICD) all can have similarly low sudden death rates and virtually identical long-term mortality. However, many patients fail to respond to drugs, and surgical risks are excessive in others, and always higher than for an ICD implant. Nevertheless, overall survival in each of these groups (and probably for patients treated with antitachycardia pacers and ablation) is about 60% at 60 months. Major challenges now are: (1) choosing therapy to maximize risk-benefit ratio; and (2) treatment of the pump failure and progressive disease that now accounts for most cardiac mortality.
