ECG abnormalities in patients with hemodynamically significant Aortic valve stenosis

  ECG abnormalities due to left ventricular hypertrophy (systolic overload due to increased ventricular systolic pressure results in left ventricular hypertrophy).

  Partial or complete atrioventricular block (due to extended calcifications involving the main bundle or its bifurcation).

ECG 1a. The above ECG belongs to a 60 years-old man with hemodynamically significant aortic valve stenosis
(peak systolic gradient 76 mmHg) and normal coronary arteries.
PR interval is prolonged (1st degree AV block). ST depression and negative T waves in leads V4, V5, V6, I and aVL
are due to left ventricular strain, not due to myocardial ischemia.

ECG 1b. The above ECG belongs to the same man.
This time, it was recorded at a calibration of 20 mm/mV.
