May indicate higher arrhythmic vulnerability during exercise recovery in HCM; leaves open prospective validation for risk stratification.
Do changes in QT dispersion during and after exercise differ according to the etiology of left ventricular hypertrophy?
Changes in corrected QT dispersion during and after exercise vary by LVH etiology, suggesting different risks of exercise-related sudden death, particularly higher in hypertrophic cardiomyopathy.
