EKG

Algorithm

Rhythm
- Rate, regularity
Atrial activity
- P wave morphology (normal? / mitrale? / pulmonale?)
- Or check for fibrillation / flutter waves
- Relation with ventricular QRS complexes (in sync? / superimposed? / other?)
- PR interval (AV blockages?)
Ventricular activity
- QRS axis
- QRS width
- Voltage, alternans
- Q waves?
- Delta waves?
ST
- ST segment (elevation? / depression?)
- (L/R)BBB (width, notches)
- T morphology (height? / biphasic? / inversion?)
- QT interval ( < 0.5 x RR ?)
