Impulse formation and conduction disturbances of the heart were investigated in 23 uraemic patients with transvenous and oesophageal electrodes. Utilizing regular atrial pacing the sinoatrial conduction time (SACT) was obtained and sinus automaticity was evaluated by measurement of the sinus node recovery time (SNRT). The atrial effective refractory period and the Wenckebach point were also determined. The effects of regular haemodialysis treatment on impulse formation and propagation disorders caused by uraemia were observed. In 16 patients transitory or permanent cardiac stimulation had to be carried out because of 2nd and 3rd degree AV block. No complication was observed during simultaneous haemodialysis and pacemaker treatment. It is concluded that the non-invasive, simple bedside oesophageal atrial stimulation method is a good alternative and should be used in the exact diagnosis of heart conduction disturbances of haemodialysed patients.
采用经静脉和食管电极，对23例尿毒症患者的心脏冲动形成和传导障碍进行了研究。通过常规心房起搏获得窦房传导时间（SACT），并通过测量窦房结恢复时间（SNRT）评估窦房结自律性。还测定了心房有效不应期和文氏点。观察了常规血液透析治疗对尿毒症所致冲动形成和传播障碍的影响。16例患者因二度和三度房室传导阻滞而不得不进行临时或永久性心脏刺激。在血液透析和起搏器治疗同时未观察到并发症。得出结论，无创、简单的床边食管心房刺激方法是一种很好的替代方法，应用于血液透析患者心脏传导障碍的准确诊断。
