Ventricular premature contractions - Bing ST段和T波变化 ST-segment and T-wave changes 正常ST段为等电段,代表从心室去极化结束到心室复极化开始的时间间隔。T波代表心室的复极化。涉及ST段和T波的异常类型有很多,从非特异性改变到急性心肌梗死。心电图识别缺血或损伤心肌区域的能力。 症状:急性心肌缺血的体征...
Changes in the ECG T-wave amplitude during anaesthesia with different anaesthetic agents were studied in 75 patients and 10 volunteers to ascertain whether T-wave amplitude changes have clinical significance in anaesthesia practice. ECG lead CB5 (central back lead) was monitored on-line during the ...
T wave changes can evolve over time from Type A to Type B pattern (Smith et al).Evolution of T-wave inversion [A-D] after coronary reperfusion in STEMI reperfusion and in Wellens syndrome (NSTEMI). Modified from Smith et al. Evolution of T-wave inversion. The ECG in acute MI, 2002...
Electrocardiographic changes in cerebrovascular accidents. The incidence of the ECG changes was 71.5% in the group with subarachnoid haemorrhage. The figures for the groups with intracerebral haemorrhage and unclassified cerebrovascular accidents were 57.1 and 41.1%, respectively. Attention has been... KE...

in the lateral leads due to the abnormally hypertrophied interventricular septum. The apical variant of hypertrophic cardiomyopathy does not result in septal Q waves as the sepum is normal in thickness in this condiction. The cardiac apex is thickened resulting in diffuse T wave changes throughot ...
ST and T wave changes opposite QRS with digoxin = 1 point Left Atrial Enlargement = 3 points Left Axis Deviation = 2 points QRS duration ≥ 90 ms = 1 point Intrinsicoid deflection in V5 or V6 > 50 ms = 1 point ECG Examples:
