Objective To study the relations between left ventricular band and cardiac murmur or premature ventricular contraction and echocardiographic features.
目的研究左心室条束的二维超声心动图特征和左心室条束与心脏杂音及室性早搏的关系。
Conclusion: Trimetazidine combined with mexiletine could significantly inhibit premature ventricular contraction in patients with coronary heart disease and slow ventricular rate.
结论：曲美他嗪联合美西律对冠心病并发的室性早搏可产生显著的抑制作用。
The relationship between the false tendon and clinical findings (murmurs, premature ventricular contraction and symptoms)was discussed, and a tentative idea was made about its mechanism.
结合文献，探讨了左室假腱索与心脏杂音、室性早搏及临床症状的关系与意义，并对其机理进行了初步分析。
During proecedure main cardiac arrhythmia found its expression in node tachycardia beat(81.8% ), ventricular premature contraction (45.5% ) and after procedure in sinus rate variation.
术中主要的心律失常是交接区心动过速（81.8％）及室上性期前收缩（45.5％），而术后主要是窦性心率增快。
