1·Objective To explore roles and machinism of L type calcium currents in pathogenesis of ventricular arrythmia after acute myocardial infarction(AMI).
目的探讨L型钙通道在急性心肌梗死（AMI）后室性心律失常发生的作用及机制。
2·The leading postoperative complications were pulmonary infections, arrythmia and pulmonary hypertensive crisis.
术后主要并发症为肺部感染、心律失常和肺动脉高压症。
3·Methods: DCG was used to analyse the arrythmia in 500 elderly patients.
方法：应用dcg对500例老年人心律失常进行分析。
4·Severe arrythmia, cardiogenic shock and infarction extension in HT group were slightly more than those in NHT group(P> 0.05).
严重心律失常，心源性休克和梗塞扩展在HT组略多（P >0 .0 5 ）。
