Objective : Polymorphic ventricular tachycardias (PVT) occur spontaneously in canine hearts under the combination of d-sotalol (S), bradycardia and phenylephrine (PE). We investigated the hypotheses that: (1) the activation patterns of the initial PV

Overdose with amitriptyline and other tricyclic antidepressants can result in ventricular conduction abnormalities as well as severe ventricular arrhythmias. The arrhythmogenic effects of these compounds may be attributed to their direct local anesth

We compared the effects of a therapeutic concentration of disopyramide with those of quinidine and lidocaine on the action potential characteristics and on the steady-state relationship between membrane potential and the maximum rate of rise of the a

Arrhythmias can result from abnormal impulse initiation or conduction. Abnormal initiation results from either automaticity or triggered activity. Enhanced automaticity may be due to a normal automatic mechanism (a normal property of the sinus node a
