Drugs for hypertension

American College of Cardiology/American Heart Association (ACC/AHA) guidelines for treatment of hypertension were last published in 2018.1 Treatment of hypertensive urgencies and emergencies is not discussed here.

Treatment of atrial fibrillation

Atrial fibrillation (AF) is the most common arrhythmia in the world. Risk factor modification, anticoagulation, rhythm control, and rate control are the four pillars of its management. American College of Cardiology/American Heart Association (ACC/AHA) guidelines on management of AF were updated recently.

Transient Inferior Lead ST Elevation During Radiofrequency Ablation of Atrial Fibrillation

Radiofrequency ablation (RFA) is a commonly performed procedure for symptomatic atrial fibrillation (AF). Herein, we describe a case of transient ST elevation during the isolation of right-sided pulmonary veins. The patient was hemodynamically stable and due to the transient nature of ST-elevation, the procedure was completed successfully. Subsequently, the cardiac catheterization was performed which did not reveal any significant obstructive coronary lesion or a thrombus. In this report, we attempt to explain possible mechanisms for ST-elevation during RFA of AF.
