Résumé
Background
P-wave terminal force in lead V1 (PTFV1) is an electrocardiographic marker of atrial electrical abnormality. We investigated whether β1-selective beta-blocker use was associated with PTFV1 in hypertensive patients with echocardiographically confirmed left ventricular hypertrophy (LVH).
Methods
This retrospective study included 182 eligible patients with essential hypertension and LVH selected from 1372 screened patients. Patients were classified as β1-selective beta-blocker users (n = 82) or nonusers (n = 100). Abnormal PTFV1 was defined as ≥ 0.04 mm s. Multivariable regression and sensitivity analyses were performed.
