Low energy intracardiac cardioversion has recently been introduced into clinical practice to treat both acute and chronic atrial fibrillation. It has also been suggested that low energy intracardiac cardioversion has a higher efficacy rate in restoring sinus rhythm than conventional external cardioversion.A prospective study was started in 41 patients (mean age 64.5 years) with chronic atrial fibrillation (mean duration 6.5 months), in order to obtain more data on low energy intracardiac cardioversion concerning: 1) time required to perform low energy intracardiac cardioversion by single venous femoral approach; 2) acute efficacy; 3) incidence of complications; 4) persistence of sinus rhythm after 1 month.Twenty patients had right atrium-coronary sinus (Group A) and 20 right atrium-left pulmonary artery (Group B) electrode configuration for defibrillation. In 1 patient the configuration was not available. In all patients (100%) sinus rhythm was acutely restored. No statistically significant differences were found between the two groups concerning mean energy and impedance required to obtain cardioversion. With mild sedation the discomfort induced by the electrical shock was minimal or mild. Only 44% of patients were in sinus rhythm 1 month after low energy intracardiac cardioversion, in spite of adequate pharmacological therapy.Low energy intracardiac cardioversion by single venous femoral approach may be considered a very effective and not time consuming procedure in acutely restoring sinus rhythm, with low complication rate; in addition the procedure was well accepted by all patients. |
