Ka. Ellenbogen et al., ARE MORE COMPLEX IMPLANTABLE CARDIOVERTER-DEFIBRILLATORS ASSOCIATED WITH AN INCREASED MORTALITY - LESSONS LEARNED FROM CLINICAL-TRIALS, The American journal of cardiology, 80(7), 1997, pp. 958
We compared 1-year survival in patients receiving implantable cardiove
rter defibrillators (ICDs) that provide only shock therapy with more a
dvanced ICDs that provide antitachycardia pacing, bradycardia pacing,
low-energy cardioversion, and advanced detection algorithms. Outcome i
n patients with advanced-generation ICD systems was similar or improve
d compared with outcome in patients receiving ICDs with only monophasi
c shock.
