Subjects and method. Ninety seven patients (103 AF episodes) who had undergone transthoracic electrical cardioversion (ECV) with a BPQS impulse according to the protocol of dose escalation (from 1-2 to 5 discharges) were analyzed. The discharge power range was from 40-65 to 195 J. The diameter of electrodes was 12 cm; its location was anterolateral. Results. Elimination of 70% of the AF episodes required 1-2 discharges; that of 18.3 and 11.7% of the episodes needed 3 and 4-5 discharges, respectively. Low power (40-85 J) discharges were found to be high ly effective (90%) in eliminating 24 hour AF; ~90% ECV success was recorded in patients with 28-48 hour episodes when greater power ( 115 J) discharges were applied to 17% of the patients. The total success rate for cardioversion was 94.2%; that of emergency ECV was 81% (p=0.022). The ECV success rate was 88.6% in patients with clinically relevant and severe
