Overview
Echocardiography is useful for evaluation of underlying structural heart disease in patients presented with bradycardia or conduction abnormality. Common indications for echocardiography in suspicion of cardiac origin of bradycardia or conduction disorder may include syncope, lightheadedness/presyncope, symptoms related to aortic stenosis, hypertrophic cardiomyopathy, heart failure.
