Overview
On EKG, endocarditis may be characterized by conduction abnormalities, low QRS voltage, ST elevation, heart block, ventricular tachycardia, and supraventricular tachycardia.
Electrocardiogram
An ECG may be helpful in the diagnosis of endocarditis. Findings on an ECG diagnostic of endocarditis include:[1][2][3][4]
- Increased PR interval
- Conduction abnormalities
- Atrioventricular dissociation which includes atrioventricular block with accelerated junctional escape
- Low QRS voltage,
- Myocardial Infarction with ST elevation
- Heart block which includes with first-degree heart block and complete heart block
- Ventricular tachycardia
- Supraventricular tachycardia
