随着科学的进步,检测窦房结(SAN)功能的方法也逐步得到改进,以往均用经静脉心内膜刺激法测定,鉴于各种创伤性检查不易为病人所接受,国内外先后开展了经食道心房调搏法检测SAN功能,但各家对其在SAN疾病的诊断价值和诊断标准上尚有分歧,现结合国内外部分资料和我们的临床实践,将经食道心房调博测定窦房结恢复时间(SNRT)结合植物神经阻 With the progress of science, the methods of detecting the function of the sinus node (SAN) have also been gradually improved. In the past, all of them were determined by transthoracic endocardial stimulation. Since various traumatic tests are not easily accepted by the patients, Transesophageal atrial pacing method to detect SAN function, but each of its diagnosis of SAN disease in the diagnostic value and diagnostic criteria are still different, combined with some domestic and foreign data and our clinical practice, the transesophageal atrial function Bo determination of sinoatrial Knot recovery time (SNRT) combined with autonomic blockade
