چکیده
Many cardiac and systemic illnesses can affect the left side of the heart. After a careful history and examination, electrocardiography and chest radiography are first line investigations. Electrocardiography can provide supportive evidence for conditions such as aortic stenosis, hypertension, and mitral stenosis.
