摘要
目的 :比较体表电位标测 (BSPM)各种图形与心电图 (ECG)诊断心肌梗死 (MI)的敏感性 ,方法采用 BSPM- 型体表电位标测微机系统 ,对 42例 MI患者和健康人的体表差电位图、峰电位图、等时间图、等积分图及 ECG进行了对比研究。结果 :前壁和下壁 MI,BSPM各种图形均有典型异常特征 ,QRS差电位图、峰电位图、Q等时图和等积分图检测 MI的敏感性 (阳性率 )分别为 10 0 % ,10 0 % ,10 0 %和 98% ,而 ECG为 81% ,差异显著 (P<0 .0 5 )。结论 :体表差电位图、等时图、峰电位图及等积分图均为诊断
AIM: To compare the sensitivity of all maps in body surface potential mapping (BSPM) and electrocardiogram ( ECG) for myocardial infarction (MI). A comparative study was made of departure maps, peak potential map, isochrone map, isointegral map in BSPM and ECG in 42 patients with MI using a BSPM Ⅲmodel computer system. RESULTS: All maps of BSPM in patients with anterior and inferior MI were appeared typical abnormal feature. The positive rates of QRS departure maps, peak potential map, Q isochrone map and isointegral map for detecting MI were 100%,100%,100% and 98% respectively, while that of ECG was 81%. The difference between BSPM and ECG was statistically significant ( P <0.05). CONCLUSION:departure maps, isochrone map, peak potential map and isointegral map of BSPM were sensitive indexes for diagnosing MI.
