According to several studies, a significant number of patients presenting with second- or third-degree atrioventricular (AV) block are receiving medications known to impair cardiac conduction. This highlights the critical importance of identifying and understanding what medications cause AV block, especially for individuals with underlying heart conditions.

According to American Heart Association guidelines, digoxin should be generally avoided in patients with second- or third-degree atrioventricular (AV) block unless a functioning pacemaker is present. However, a nuanced approach is required, as the answer to 'Is digoxin contraindicated in AV block?' is not a simple yes or no, but depends heavily on the type and severity of the heart block.

Atropine is a first-line medication for treating symptomatic bradycardia, a condition where the heart beats too slowly. But specifically, what will atropine do to the heart? This article explores its mechanism, uses, and effects on cardiac function.

According to ACLS guidelines, atropine is a first-line medication for symptomatic bradycardia, with a standard dose of 1 mg IV. A key question is what rhythm you do not give atropine to, particularly in high-degree AV block where it may be ineffective or harmful.
