【摘要】 为了解急性心肌梗死患者的Q-T_d、J-T_d动态变化,观察105例急性心肌梗死患者发病后第1—7天、第14、21及28天心电图的Q-T_d和J-T_d。结果显示:Q-T_d、J-T_d以发病后第2天(65.18±34.08,59.24±32.18ms)及第3天(63.18±28.51;60.57±26.82ms)为最大。提示急性心肌梗死后第2—3天Q-T_d、J-T_d达峰值,可作为预测病情的参考指标。更多还原

【Abstract】 In order to realize dynamic changes of Q-T dispersion (Q-Td) and J-T dispersion (J-Td) of patients with acute myocardial infarction (AMI) Q-Td and J-Td shown in ECGs of 105 patients with AMI were analysed on 1st day to 7th day 14th day 21st and 28th day. Results proved Q-Td and J-Td to be greatest on second day (65.43±34.08ms, 59. 20±32.18ms) and on third day (63.18±28. 15ms, 60.57±26. 82ms), suggesting that Q-Td and J-Td greatest values on second and third day might be considered as an indicator for prognosis.更多还原
