Efficacy of Antitachycardia Pacing in Patients Presenting with Cardiac Arrest Export

@article{citeulike:5023142, abstract = {The efficacy of antitachycardia pacing (ATP) incorporated into implantable cardioverter defibrillators (ICDs) was assessed in 29 consecutive survivors of cardiac arrest, not attributable to acute myocardial infarction, ischemia, or drug and electrolyte effects.
