摘　　要：目的:为了解急性心肌梗死Q-T离散度的动态变化,以及与恶性室性心律失常、左房负荷(PTFV1)的关系.方法:测量80例急性心肌梗死病人包括死亡前)住院期间Q-T离散度,比较急性心肌梗死(AMI)入院与出院时Q-T离散度(Q-Td)及校正Q-T离散度(Q-Tcd),比较Q-Td与PTFV1及恶性室性心律失常的相关性.结果:80例AMI住院期间Q-Td动态变化揭示了Q-Td与恶性室性心律失常、PTFV1的密切关系,62例急性心肌梗死Q-Td及Q-Tcd入院时较出院有非常明显延长(P＜0.05).结论:Q-Td可作为预测恶性室性心律失常及心功能不全的一项敏感指标,不失为无创性评估急性心肌梗死预后的手段之一.Background: To study Q-T duration dispersion and its relation with malignant ventricular arrhythmia and PTFV1.Methods: 80 cases of AMI were entered this research .All patient’s Q-T duration disper- sion and Q-Tcd (corrected Q-T duration dispersion) were measured and compared respectively on the admission and discharged; as well as the relative analysis between Q-Td and malignant ventricular arrhythmia and PTFV1 were carried on. Results: the dynamic change of Q-Td showed there are significant relation between Q-Td and malignant arrhythmia and PTFV1. The Q-Td and Q-Tcd were significant prolonged at admission than that at be- ing discharged (P<0.05). Conclusions: Q-Td could be taken as a sensitive predictive factor to reflect the occur- rence of the malignant ventricular and cardiac dysfunction, it is also a valuable and non-invasive methods to evaluating the prognosis of the acute myocardial infarction.
