Atrial fibrillation (AF) is a prevalent arrhythmia with major risk factors such as becoming older, heart failure, left ventricular hypertrophy, coronary heart disease, and hypertension. This study aimed to measure the prevalence of Left Ventricular Hypertrophy (LVH) in patients with Atrial Fibrillation (AF) and hypertension. Materials and Method: From September 1, 2018, to February 28, 2019, this cross-sectional study was carried out on a group of 100 patients who had both AF and hypertension.
