Little information is available regarding cardiac automatism and conduction disturbances in patients affected by congestive (CCM) or hypertrophic (HCM) cardiomyopathies. For this reason 29 patients with HCM (10 cases) and CCM (19 cases) and disturbances of sinus node automaticity or AV conduction underwent an electrophysiologic study. Eight patients affected by HCM were also submitted to cardiac catheterization. Sinus node function was normal in each of the HCM patients, and impaired in 6 of the 19 CCM patients. The intra-atrial conduction was prolonged in only one CCM case. One HCM and 2 CCM patients showed an impaired intranodal AV conduction. Thirteen patients (44%) showed a prolonged HV interval (3 HCM and 10 CCM patients). No calcific deposits on the aortic valve were discovered by X ray stratigraphic examination in any of the patients. In 6 cases a progression of the conduction disturbances was observed. Ventricular pre-excitation was present in 4 patients (13%).
关于充血性心肌病（CCM）或肥厚性心肌病（HCM）患者的心脏自律性和传导障碍，目前可用信息较少。因此，对29例患有HCM（10例）和CCM（19例）且伴有窦房结自律性或房室传导障碍的患者进行了电生理研究。8例HCM患者还接受了心导管检查。所有HCM患者的窦房结功能均正常，19例CCM患者中有6例窦房结功能受损。仅1例CCM患者的心房内传导延长。1例HCM患者和2例CCM患者表现为结内房室传导受损。13例患者（44%）的HV间期延长（3例HCM患者和10例CCM患者）。X线断层检查未在任何患者的主动脉瓣上发现钙化沉积。6例患者观察到传导障碍进展。4例患者（13%）存在心室预激。
