采用无创伤性食管心房调搏法，测定７０例流行性出血热（ＥＨＦ）患者发病期与恢复期房室结（ＡＶＮ）的电生理参数，时其中３１例分别测定了发病早期和发病晚期的参数，对４例重型患者测定了４次。分别比较了发病期与恢复期，发病早期与发病晚期，轻型发病期与恢复期，中重型发病期与恢复期ＡＶＮ功能。结果显示：发病期，尤其是发病早期，ＡＶＮ功能损害明显，中重型较轻型损害明显。ＥＨＦ对ＡＶＮ功能的损害是ＥＨＦ某些心律失常的直接原因。无创伤性食管心房调搏法是检查ＥＨＦ患者心脏损害的安全、可靠指标。
The non-invasive esophageal atrial pacing method was used to determine the electrophysiological parameters of 70 cases of patients with epidemic hemorrhagic fever (EHF) during the onset and convalescence of atrioventricular node (AVN), of which 31 cases were measured early onset and late onset of the parameters , Four cases of heavy patients were measured 4 times. The incidence and recovery, early onset and late onset, mild onset and recovery, moderate to severe onset and recovery of AVN function were compared. The results showed that: during the onset, especially early onset, AVN function was significantly damaged, moderate to severe lighter damage more obvious. EHF damage to AVN function is the direct cause of some cardiac arrhythmia in EHF. Non-invasive esophageal atrial pacing method is to check the safety of EHF patients with heart damage, a reliable indicator.
