Which medication might precipitate atrial tachycardia in a patient?

Digoxin is a medication that can precipitate atrial tachycardia, especially in patients who have heart conditions. It works by increasing the force of heart contractions and can have various effects on the electrical conduction system of the heart. One of the significant effects of digoxin is its impact on the atrioventricular (AV) node, leading to increased automaticity in the atria, which can result in atrial arrhythmias such as atrial tachycardia. This risk is heightened, especially in the context of electrolyte imbalances or underlying heart disease.

In contrast, aspirin is an antiplatelet medication used primarily to prevent blood clots and has no direct effect on heart rhythms. Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor commonly used to manage hypertension and heart failure, and it does not typically affect heart rate or rhythm in a way that would lead to atrial tachycardia. Beta-blockers, on the other hand, are antiarrhythmic agents used to manage various tachyarrhythmias, including atrial tachycardia itself, by slowing down the heart rate and reducing the conduction through the AV node. Thus, their role is protective rather than precip
