During evaluation for palpitations, presyncope, or syncope, seven pregnant women had documented ventricular tachycardia. Before pregnancy none had a history of significant cardiac disease or symptomatic arrhythmia. The tachycardia rate ranged from 117 to 250 beats/min and lasted up to 65 seconds. Arrhythmia evaluation in five of the patients suggested catecholamine-sensitive ventricular tachycardia. This diagnosis was supported by either a positive relation to exercise or isoproterenol infusion, suppression of arrhythmia by beta-blockade or sleep, and lack of induction of arrhythmia by programmed electrical stimulation of the heart. The arrhythmias resolved in one patient soon after evaluation and in one other patient after 2 months of controlling therapy. Five other patients continued to receive therapy throughout pregnancy. Delivery was accomplished in all patients without significant maternal or neonatal complications.
在对心悸、晕厥前状态或晕厥进行评估期间，有7名孕妇记录到室性心动过速。怀孕前，她们均无严重心脏病史或症状性心律失常病史。心动过速的心率范围为117至250次/分钟，持续时间长达65秒。对其中5例患者的心律失常评估提示为儿茶酚胺敏感性室性心动过速。运动或静脉输注异丙肾上腺素后心律失常加重、β受体阻滞剂或睡眠可抑制心律失常、心脏程序性电刺激不能诱发心律失常等表现均支持这一诊断。1例患者在评估后不久心律失常即消失，另1例患者在接受2个月的控制治疗后心律失常消失。其他5例患者在整个孕期持续接受治疗。所有患者均顺利分娩，未出现严重的母体或新生儿并发症。
