本文报告65例室性早搏q波的临床意义,其中9例心电图同时出现q波、ST段抬高和原发性T波改变,反映心肌坏死的急性期;26例伴有q波和原发性T波改变,ST段不抬高,反映心肌坏死的亚急性期;30例仅见q波,反映心肌坏死的恢复期。病因包括急性心肌梗塞、急性心肌炎、心肌炎后遗症、冠心病、充血性心肌病、风心病和先心病等。大白鼠实验性非梗塞性心肌坏死诱发的室性早搏亦可出现q波、ST段抬高和原发性T波改变。认为这种非梗塞性心肌坏死的图形改变,是心肌坏死或心肌纤维化的结果。
This article reports the clinical significance of 65 cases of premature ventricular contractions Q waves, including 9 cases of simultaneous q-wave ECG, ST elevation and primary T wave changes, reflecting the acute myocardial necrosis; 26 cases with q wave and primary T wave changes, ST segment does not rise, reflecting the subacute myocardial necrosis; 30 cases only see q wave, reflecting the recovery of myocardial necrosis. Causes include acute myocardial infarction, acute myocarditis, myocarditis sequelae, coronary heart disease, congestive cardiomyopathy, rheumatic heart disease and congenital heart disease. Rat ventricular premature beats induced by experimental non-infarction myocardial necrosis may also appear q wave, ST elevation and primary T wave changes. This pattern of non-infarcted myocardial necrosis is thought to be the result of myocardial necrosis or myocardial fibrosis.
