目前对于病态窦房结综合征(Sick Sinus Syndrome以下简称SSS)的诊断主要依靠临床表现、常规心电图(ECG)、动态心电图(DCG)、药物及运动激发试验、电生理检查等,其中运动试验因其特异性较差,加之相当部分患者心功能及其全身状况不能耐受此项检查,作为诊断方法应用较少;而DCG及其它无创电生理检查(如经食道心房调搏测定窦房结 At present, the diagnosis of Sick Sinus Syndrome (SSS) mainly depends on the clinical manifestations, conventional ECG, DCG, drug and motor excitation test, electrophysiological examination, etc., of which motor test Its specificity is poor, combined with a considerable part of the patient’s cardiac function and general condition can not tolerate this test, as a diagnostic method less; and DCG and other non-invasive electrophysiological examination (such as transesophageal atrial pacing determination of the sinoatrial node
