[Early Systolic Dysfunction of Left Ventricular Myocardium Is Reflected On Electrocardiogram of Patients With Aortic Stenosis].

Aim: to study relation between electrocardiographic (ECG) criteria of left ventricular hypertrophy (LVH) and parameters of tissue Doppler (TD) and LV strain in patients with aortic stenosis (AS) with preserved LV ejection fraction.

Material And Methods: We examined 80 patients with degenerative AS of all degrees of severity. Examination included history, blood serum cholesterol and creatinine, 12 lead ECG, routine echocardiography (EchoCG), TD, and LV global longitudinal peak strain (GLPS) in apical positions of 2-dimensional EchoCG.
