The medications that most commonly cause first-degree heart block are those that increase the refractory time of the AV node, thereby slowing AV conduction. These include calcium channel blockers , beta-blockers , cardiac glycosides , and anything that increases cholinergic activity such as cholinesterase inhibitors .
Antiarrhythmic agents, also known as cardiac dysrhythmia medications, are a class of drugs that are used to suppress abnormally fast rhythms (tachycardias), such as atrial fibrillation, supraventricular tachycardia and ventricular tachycardia. Many attempts have been made to classify antiarrhythmic agents.
Unless a pacemaker is present, beta blockers can severely depress conduction in the AV node, resulting in a reduction of heart rate and cardiac output. One should be very cautious with the use of beta blockers in tachycardia patients with Wolff-Parkinson-White Syndrome, as it can result in life-threatening arrhythmia in certain patients.

Class III antiarrhythmic drugs are potassium channel blockers that cause QT prolongation and are associated with TdP. Amiodarone. Amiodarone works in many ways. It blocks sodium, potassium, and calcium channels, as well as alpha and beta adrenergic receptors. Because of its multiple actions, amiodarone causes QT prolongation but TdP is rarely ...
