“…There was no significant difference in heart rate variability between controls and the NHVT group (TF, 43 (13) (13) ms; LF, 12 (6) v 13 (9) ms; and HF, 7 (4) v 8 (6) ms; NS). The difference in heart rate variability, however, was highly significant between the CHF group and the controls (TF, 23 (12) v 43 (13) ms; LF, 12 (8) v 28 (9) ms; HF, 8 (5) v 14 (7) ms; p < 0-001).…”

In patients with congestive heart failure, heart rate variability is significantly decreased. The depressed heart rate variability is principally related to the degree of left ventricular impairment and is independent of aetiology and the presence of ventricular arrhythmias. The data suggest that analysis of heart rate variability does not help the identification of patients with congestive heart failure at increased risk of sudden death.

“…Many studies have examined the relationship between left ventricular hypertrophy (LVH), ventricular arrhythmia (VA), and sudden cardiac death (SCD) since the initial report from the Framingham cohort [ 1 ] addressed LVH as a strong independent predictor of cardiovascular morbidity and mortality. Several [ 2 – 7 ] but not all [ 8 – 10 ] prior investigations have shown an elevated incidence of ventricular tachyarrhythmias among individuals with LVH detected by either echocardiography or electrocardiography. Nevertheless, it is unclear if elevated left ventricular mass (LVM) as a result of hypertension poses a separate risk for ventricular tachyarrhythmias.…”

Background Left ventricular hypertrophy (LVH) is associated with an increased risk of ventricular arrhythmias and cardiovascular mortality. The study objective was to investigate the effect of LVH severity on the complexity and severity of ventricular arrhythmias among a subset of Egyptian hypertensive patients. Results The study cohort consisted of 60 hypertensive patients with LVH as diagnosed by echocardiography. Their mean age was (53.7 ± 12.3) years. 36 males (40%) and 24 females (60%). Diabetes mellitus was found in 26 patients (43%), 41% of these cases were smokers. 48-h Holter monitoring was performed in all cases to assess the frequency of ventricular premature contractions (VPC) and their complexity using the Lown grading. Increasing posterior wall thickness end diastole (PWTd) was an independent predictor of increasing VPC frequency, each 1 mm increase in the PWTd is associated with a 1.26% increase in the VPC% among total heart beats (b = 12.6, p < 0.001). Higher-grade VPCs—defined as grade 4a, 4b, and 5—were seen in 29 patients (48.3%). Interventricular septum thickness end diastole, PWTd, left ventricular mass, and left ventricular mass index (LVMI), were significantly higher among patients with higher Lown grading (p < 0.001). Using logistic regression analysis, female sex and LVMI were independent predictors of more complex VPC (OR = 8.766, p = .014), (OR = 1.096, p < 0.001), respectively. Among females, LVMI of more than 120 g/m2 can differentiate between high- and low-grade VPCs with 71% sensitivity and 80% specificity, while among males, LVMI of more than 129.5 g/m2 can differentiate between high and low-grade VPCs with 86% sensitivity and 66% specificity. Conclusions The frequency and complexity of ventricular arrhythmias among hypertensive heart disease are correlated with the severity of ventricular hypertrophy. Female sex and increasing left ventricular mass index are independent predictors of more complex forms of ventricular arrhythmias.
