title: [Optimal parameters for electrical auricular defibrillation].
abstract: In acute experiments on dogs the chest was opened and auricular flutter and fibrillation were induced. Current, energy and charge thresholds which eliminated this arrhythmia by the monopolar direct impulse of 1--15 ms duration were determined. The current and energy values that evoked the auricular defibrillation during direct application of the electrodes to them were minimal when the impulses of 8 ms were used: 113 +/- 13.7 mA and 10.4 +/- 2.6 mWs in elimination of the flutter, and 275 +/- 18.2 mA and 62.3 +/- +/- 9.0 mWsec in elimination of the fibrillation. The current that restored the nomotopic rhythm during direct auricular defibrillation was 50 times less than that determined during the transthoracic auricular defibrillation in dogs. The efficacy of direct auricular defibrillation indicated the necessity of the elaboration of an adequate method for its application in clinical practice.
