Abstract
The pacing maneuvers for supraventricular tachycardia with cycle length alternans are sometimes difficult, especially when diagnostic ventricular pacing does not conduct to the atrium. Even in such a situation, critical diagnostic findings can be obtained by spontaneous premature ventricular contraction.
摘要
对于伴有周期长度交替的室上性心动过速，起搏操作有时会很困难，尤其是在诊断性心室起搏不能传导至心房时。即使在这种情况下，通过自发性室性早搏也可获得关键的诊断结果。
