Overview
The electrocardiogram in cardiac tamponade usually demonstrates sinus tachycardia, and may sometimes show reduced QRS voltage and electrical alternans.
Electrocardiogram
EKG findings of cardiac tamponade are:
- Sinus tachycardia
- Electrical alternans (beat-to-beat alterations in the QRS complex due to the swinging of the heart in pericardial fluid)
- Low voltage QRS complexes ([[Low QRS voltage] is defined as maximum QRS amplitude in precordial lead < 1 mV and < 0.5 mV in the limb leads due to insulating properties of fluid) [1].
- ST segment [2].
- EKG findings of pericarditis and pericardial effusion may be seen if these conditions are accompanying tamponade.
