摘要
Abstract
Objective To investigate the value of sinus heart rate turbulence in patients with acute myocardial infarction(AMI). Methods 9 patients with acute ST segment elevated myocardial infarction regarded as ventricular fibrillation group underwent percutaneous transcoronary intervention, and 49 without ventricular fibrillation were regarded as nonventricular fibrillation group. The difference of heart rate turbulence in the two groups was compared. Results During diastasis, the left ventricular internal diameter and ejection fraction in ventricular fibrillation group and non-ventricular fibrillation group were (48.0 ±5.7)mm, (0.59 ±0. 11) and(45.8 ±5.0)mm, and (0.58 ±0.10) respectively, and there was significant difference between the two groups( P ＜0.05 ). The values of turbulence onset and turbulence slope in the ventricular group were (0.81 ±2.03) and (2.18 ± 1.06) ms/RR stage, but were ( -0. 65 ±2. 64) and(4. 05 ± 1.22)ms/RR stage in non-ventricular fibrillation, and there was significant difference ( P ＜ 0.05 ). Conclusion Sinus heart rate turbulence is dramatically blunted in the acute ST segment elevated myocardial infarction patients,and autonomic nervous system dysfunction may partially occur in early AMI.关键词
