A patient with the sick-sinus syndrome was evaluated because of symptomatic deterioration after insertion of a ventricular demand pacemaker. Clinical features of the ventricular pacemaker syndrome were recognized and confirmed by electrophysiological and hemodynamic studies. Phase analysis--a new technique for detecting patterns of cardiac emptying from gated cardiac blood-pool scintigrams--demonstrated a pattern consistent with 1:1 ventriculo-atrial conduction. Phase analysis of the gated cardiac blood-pool scintigram may be useful in the assessment of patients with ventricular demand pacemakers who complain of fatigue and effort intolerance.
一名患有病态窦房结综合征的患者在植入心室按需起搏器后因症状恶化而接受评估。通过电生理和血流动力学研究识别并证实了心室起搏器综合征的临床特征。相位分析——一种从门控心血池闪烁图检测心脏排空模式的新技术——显示出与1:1室房传导一致的模式。门控心血池闪烁图的相位分析可能有助于评估抱怨疲劳和运动不耐受的心室按需起搏器患者。
