Why the study?
Does left ventricular hypertrophy increase QT dispersion and alter heart rate variability in hypertensive men?
Does left ventricular hypertrophy increase QT dispersion and alter heart rate variability in hypertensive men?
Left ventricular hypertrophy in hypertensive men is associated with increased inhomogeneity of ventricular repolarization (QT dispersion), which may explain the increased susceptibility to ventricular tachyarrhythmias.
No takes yet. Share an insight, caveat, or question.
LVH links to greater QT dispersion in hypertension, suggesting possible arrhythmic vulnerability; leaves open causal role and need for prospective validation.
Perkiömäki et al. (1996) studied this question.
