The role of EP testing prior to insertion of a multiprogrammable implantable cardioverter defibrillator (ICD), however, is unclear.<\/jats:p><jats:p> <jats:italic>Methods and Results:<\/jats:italic> This study was a retrospective review of outcome in 66 survivors of an initial episode of out\u2010of\u2010hospital VF not associated with a Q wave myocardial infarction or reversible causes, treated with transvenous ICDs as first\u2010line therapy. Patients were excluded from the study if they had a previous history of monomorphic ventricular tachycardia (VT), a clinical history suggestive of supraventricular tachycardia, or had undergone preoperative EP testing. Fifty\u2010two of the patients (79%) were male with an average age of 58 \u00b1 11 years. Coronary artery disease was present in 43 patients (66%), cardiomyopathy in 15 patients (23%), and valvular heart disease in 1 patient (1.5%). Seven patients (11%) had no detectable structural heart disease. The mean left ventricular ejection fraction was 0.40 \u00b1 0.16. With an average follow\u2010up of 25 \u00b1 12 months, survival free of death from any cause was 100%. Twenty\u2010three patients (35%) experienced 48 episodes of recurrent rapid VT or VF (average cycle length: 236 \u00b1 47 msec) treated by their device. The mean time to first therapy was 223 \u00b1 200 days. Only one of these patients also received antitachycardia pacing for two episodes of VT. One patient (1. 5%) temporarily received amiodarone after removal of an infected device that was subsequently replaced. No other patient received antiarrhythmic drug therapy.<\/jats:p><jats:p> <jats:italic>Conclusion<\/jats:italic>: After a cardiac arrest due to primary VF, select patients treated with multiprogrammable ICDs can be managed successfully without baseline EPS or antiarrhythmic drug therapy.<\/jats:p>","DOI":"10.1111\/j.1540-8167.1996.tb00515.x","type":"journal-article","created":{"date-parts":[[2007,5,14]],"date-time":"2007-05-14T01:54:58Z","timestamp":1179107698000},"page":"197-202","source":"Crossref","is-referenced-by-count":17,"title":["Management
