本文用35导联胸壁心电图标测方法,对21例急性前壁心肌梗塞患者进行R 波、Q 波和ST段变化观察。∑R 于胸痛发作后12小时内迅速下降,∑Q 逐渐增大,24小时内变化最显著,∑ST12小时内迅速下降,48小时后渐趋稳定。12例(57%)R 波消失,Q 波在发病后12小时内形成,另9例(43%)于24小时内形成。
In this paper, with a 35-lead chest wall ECG method, the changes of R wave, Q wave and ST segment in 21 patients with acute anterior myocardial infarction were observed. ΣR decreased rapidly within 12 hours after onset of chest pain, ΣQ gradually increased, the most significant changes within 24 hours, ΣST12 hours decreased rapidly, 48 hours later stabilized. R wave disappeared in 12 patients (57%), Q wave formed within 12 hours after onset, and the other 9 cases (43%) formed in 24 hours.
