The Accuracy of the Electrocardiogram in Identifying Chronic Heart Failure due to Left Ventricular Systolic Dysfunction

open access: yesمجلة المختار للعلوم, 2013
There is a common assumption that a normal electrocardiography rules out chronic heart failure due to left ventricular systolic dysfunction (LVSD). In this research work, an assessment of the value of electrocardiography in identifying patients with ...
