24-Hour Electrocardiographic (ECG) Holter Recording during Hypertensive Cardiopathy in Health Facilities in Lome

Abstract
Objective: To evaluate the 24-hour Holter ECG recording in hypertensive heart disease. Methods: This was a descriptive and analytical cross-sectional study on files of patients with hypertensive heart disease, carried out from October 2016 to October 2019, in two health facilities in Lome (TOGO). Electrical left ventricular hypertrophy (LVH) was defined by the Sokolow-Lyon and Cornell indices. On echocardiography, the HVG according to the criteria of the American Society of Echocardiography, was the characteristic retained for a CH. Holter-ECG recordings were carried out over 24 hours by two Holter devices. Results: 107 patients were included, with a sex ratio of 1.89 (M / F). The mean age was 62.2 ± 12 years. The mean duration of the evolution of hypertension was 10.8 ± 9.1 years. On standard ECG, arrhythmias were more frequent (32.6%) with ACFA in 5.6% of cases. The prevalence of echocardiographic HVG was 74.8%, predominantly concentric, and was significantly found in hypertensive patients over 10 years of age. During the 24-hour Holter ECG recording, ACFA was the common arrhythmia (30%), episodic in 90.6% of cases and permanent 9.4% and was statistically associated with OG size, sex and age. The Holter ECG detected sustained ventricular tachycardia in 7 patients (6.5%). The Recording was normal 12.1% of the time. Conclusion: Hypertensive heart disease is the first of the cardiac complications of hypertension. The Holter ECG is a tool for the detection of fatal severe paroxysmal events that go unnoticed on the surface ECG such as AC/AF, sustained ventricular tachycardias.
