摘要
为了解急性心肌梗死患者严重心律失常与Q-T延长的关系,观察32例急性心肌梗死、20例陈旧性心肌梗死及50例对照组的Q-T_a、J-T_d及Q-T_(cd)的变化,结果急性心肌梗死组的Q-T_d、J-T_d及Q-T_(cd)分别为65.6±22.7,59.4±22.6及70±25ms,均显著高于陈旧性心肌梗死组和对照组(P<0.01)。并发现急性心肌梗死组严重室性心律失常发生率、心功能状况与Q-T_d延长程度有关。揭示Q-T_d对判断心肌梗死病情程度有一定参考价值。
In order to study relationship between ventricular arrhythmia and prolonged Q-T in patients with acute myocardial infarction. Q-T dispersion (Q-Td), J-T dispersion (J-Td) and Q-Tc dispersion (Q-Tcd) in 32 patients with acute myocardial infarction, 21 old myocardial infarction and 50 normal subjects were analyzed in this study. Results showed Q-Td, J-Td and Q-Tcd values in acute myocardial infarction were higher than those in old myocardial infarction ( P<0. 01) and controls (P<0.01). It was also shown that in acute myocardial infarction, severe ventricular arrhythmia and cardiac function were closely related to prolonged Q-Td. Therefore, prolonged Q-Td might be significant in serious myocardial infarction.
