[Transthoracic ventricular defibrillation: effectiveness of bipolar sinusoidal impulse].
The efficacy of low-energy bipolar pulse is studied in 41 patients with sudden heart arrest caused by ventricular fibrillation (VF). Maximal energy of effective charges during defibrillation of patients with or without acute myocardial infarction and primary VF (30 episodes) was only 90 J x 1-2. For eliminating secondary VF (76 episodes), maximal energy of 165-195 J x 1-5 was needed in only 25% patients. Total efficacy of charges of at least 115 J x 1-2 in patients with primary and secondary VF was 87%. The results indicate a high efficacy of low-energy bipolar sinusoidal charges for elimination of VF in patients with acute myocardial infarction and other forms of coronary disease.
