WebIt is altered by left ventricular or right ventricular hypertrophy or by bundle branch blocks. It is a very straightforward measurement that, once it has been grasped, can be calculated instantaneously: find the QRS complex in the I and aVF leads (because these look at the heart at 0° and +90°, respectively) WebSupporting: 4, Contrasting: 1, Mentioning: 44 - In hypertensive patients with ECG evidence of LVH, increased LVMI and LVH are associated with a prolonged QT interval and increased QT dispersion. These findings suggest that an increased vulnerability to repolarization-related ventricular arrhythmias might in part explain the increased risk of sudden death in …
