目的观察心肌梗死(MI)患者急性期和陈旧性期窦性心率振荡(HRT)的变化。方法记录27例MI患者急性期[(3.8±0.3)d]及陈旧期[(84.1±3.0)d]24h动态心电图,据2次24h动态心电图计算振荡起始(TO)及振荡斜率(TS),分析HRT的变化。结果MI从急性期演变至陈旧期TO明显减小[(0.17±0.12)%至-(1.45±0.45)%],P<0.01;TS明显增大[(1.70±0.56)至[(8.87±1.91)ms/RR],P<0.01。结论心肌梗死患者急性期HRT异常,至陈旧期HRT可恢复正常。
Objective To observe the change of sinus rhythm of heart rate (HRT) in acute and old patients with myocardial infarction (MI). Methods The electrocardiogram of 27 MI patients with acute phase [(3.8 ± 0.3) d] and obsolete [(84.1 ± 3.0) d] 24h were recorded and the oscillating onset (TO) and oscillation slope , Analysis of HRT changes. Results The change of MI from acute phase to obsolete TO decreased obviously ([(0.17 ± 0.12)% vs - (1.45 ± 0.45)%], P <0.01; TS significantly increased from 1.70 ± 0.56 to 8.87 ± 1.91 ) ms / RR], P <0.01. Conclusions HRT in patients with acute myocardial infarction is abnormal, and HRT can recover to normal in patients with myocardial infarction.
