Antitachycardia Pacing, Cardioversion, and Defibrillation: From the Past to the Future

摘要: Nearly three decades ago, it was known that ventricular tachycardias in the presence of bradycardia could be prevented by pacing at physiologic rates [1–10]. Temporary and implanted pacers have long been used to prevent rate support or suppressing premature complexes (VPCs) terminate using competitive stimulation. In 1970s, implantable antitachycardia pacemakers became commercially available. That decade saw many new applications an increased understanding mechanisms involved tachycardia termination. It appeared would play a major role treatment tachycardias. Pacing failed, however, reach projections for reasons: physicians often fail recognize benefits temporary as well permanent pacing; units require frequent reprogramming, rapid responses can occur if atrial fibrillation is provoked; younger patients balked because “image” elderly. The danger accelerating (VT) into (VF) produced great reluctance implant VT cardioverter defibrillator (ICD) further relegated background.
