Acute Mechanical Response to Anti-arrhythmic Drug Therapy

Summary

The aim of this study is to determine if anti-arrhythmic drugs with a sodium channel-blocking mechanism exert a detrimental electromechanical effect on cardiac function in patients depending upon baseline intraventricular conduction and left ventricular function.
