Cardiac arrest occurred in a male Labrador Retriever dog weighing 27.8 kg during induction to anesthesia. Immediately after the failure of resuscitation by the external cardiac compression, thoracotomy was performed and open chest direct current (DC) counter shocks were applied with routine emergency medications. Then the dog recovered consciousness. Although cardiac rhythm just after resuscitation was sinus tachycardia with paroxysmal supraventricular tachycardia, multifocal ventricular arrhythmia occurred 2 hr after resuscitation. This arrhythmia might be the result from reversible cardiac lesions due to DC counter shock.
一只体重27.8千克的雄性拉布拉多猎犬在麻醉诱导期间发生心脏骤停。在胸外心脏按压复苏失败后，立即进行开胸手术，并使用常规急救药物进行开胸直流电（DC）除颤。随后这只狗恢复了意识。尽管复苏后即刻的心律为窦性心动过速伴阵发性室上性心动过速，但复苏后2小时出现了多灶性室性心律失常。这种心律失常可能是直流电除颤导致的可逆性心脏病变的结果。
