Abstract
The aim of our work was to investigate the effect of amitriptyline, citalopram and venlafaxine on the heart during ischemic- reperfusion (l-R) injury. Amitriptyline prolonged both QRS complex and QTc interval duration; citalopram and venlafaxine prolonged only QTc interval duration. Amitriptyline worked most proarrhythmogenic, citalopram least; venlafaxine increased the heart rate during ischemia; however, prolonged QTc interval at the beginning of reperfusion was followed by serious dysrhythmias.
