Abstract Background: Hypothyroidism can lead to a decrease in cardiac output, an increase in systemic vascular resistance, lower arterial compliance, impaired cardiac muscle relaxation, decreased heart rate, and decreased stroke volume contributed to heart failure. Aim: Is to demonstrate ventricular function changes in patients with congenital hypothyroidism and investigate the effects of L-T4 substitution therapy using M-mode echocardiography, tissue doppler imaging (TDI) and electrocardiography (ECG). Also to detect the role of ultrasound in congenital hypothyroidism diagnosis |
