What does this research mean for the field?

Left ventricular hypertrophy induced by physical training is not associated with an increase in QT dispersion, whereas pathological left ventricular hypertrophy secondary to hypertension significantly increases QT dispersion.

Why the study?

Does left ventricular hypertrophy due to physical training or hypertension show similarities in QT length and QT dispersion?

Population

51 subjects including 17 essential hypertensive patients, 17 athletes involved in agonistic activity, and 17…

Implication

QT dispersion may distinguish physiological from pathological LVH; leaves open prospective validation for arrhythmic risk.

Structured PICO

Does left ventricular hypertrophy due to physical training or hypertension show similarities in QT length and QT dispersion?

Population

51 subjects including 17 essential hypertensive patients (mean age 27.7), 17 athletes involved in agonistic activity (canoeing) (mean age 24.8), and 17 normotensive healthy subjects as a control group (mean age 24.8).

Intervention

Pathological left ventricular hypertrophy (essential hypertension) and physiological left ventricular hypertrophy (athletic training)

Comparator

Normotensive healthy subjects

Outcome

QT length and QT dispersion (QT max, QTc max, QT min, QTc min, DeltaQT, DeltaQTc)surrogate

Physiological LVH induced by athletic training is not associated with increased QT dispersion, unlike pathological LVH secondary to hypertension.
