This paper reports a study of the effects of ECT (electroconvulsive therapy) upon cardiac function (as judged by electrocardiographic changes) in 24 patients who were given 139 treatments in all. Of the 24 patients 13 were studied over a 24-h period using monitoring equipment. No potentially dangerous arrhythmias were encountered. Modified ECT was found to give rise to sinus tachycardia, which was considerably more prolonged than previously reported. The tachycardia was shown in some cases to be accompanied by a depression of the ST segment and may hence be potentially harmful to those with pre-existing ischaemic heart disease. In such patients consideration should be given to the prior administration of beta-adrenergic blocking drugs and/or oxygen.
本文报告了一项针对24例患者进行的研究，这些患者共接受了139次电休克治疗（ECT），研究其对心脏功能的影响（通过心电图变化判断）。在这24例患者中，13例在24小时内使用监测设备进行了研究。未发现有潜在危险的心律失常。发现改良ECT会引发窦性心动过速，其持续时间比之前报道的要长得多。在某些情况下，心动过速伴有ST段压低，因此可能对已有缺血性心脏病的患者有潜在危害。对于这类患者，应考虑预先给予β-肾上腺素能阻滞剂和/或氧气。
