Which one of the following mechanisms describes the general action of antidysrhythmic agents?

Question

Quizplus · Accepted Answer

Antidysrhythmic agents typically work by impeding the movement of ions across cardiac cell membranes, which can help to stabilize the heart's electrical activity and prevent arrhythmias. This can involve various mechanisms, such as blocking ion channels, altering ion concentrations, or affecting ion exchange pumps. Enhancing cardiac automaticity (B) or impulse conduction (D) could actually increase the risk of arrhythmias, while shortening the cardiac action potential (C) might not be effective for all types of arrhythmias.
