Overview
On EKG, endocarditis may be characterized by conduction abnormalities, low QRS voltage, ST elevation, heart block, ventricular tachycardia, and supraventricular tachycardia.[1]
Electrocardiogram
On EKG, endocarditis may be characterized by conduction abnormalities, low QRS voltage, ST elevation, heart block, ventricular tachycardia, and supraventricular tachycardia.[1] EKG may be useful in the detection of the 10% of patients who develop a conduction delay during infective endocarditis by documenting an increased PR interval. If myocardial infarction is present, it may be due to vessel occlusion with ST elevation myocardial infarction or it may be due to distal embolism which may result in non ST elevation MI.
