- Different forms of P waves in atrial extra systoles
- Impact on the PQ interval
AV Node Extra Systoles
- Characteristics of AV node extra systoles
- ECG signal changes and hidden P waves
- Effects on the QRS complex
- Different locations of the pathological focus in the AV node
Ventricular Extra Systoles
- Characteristics of ventricular extra systoles
- Wide and deformed QRS complex
- Absence of P wave
- Duration of the QRS complex
Types of Extra Systoles
- Paired ventricular extra systoles
- Bigenial ventricular extra systoles
- Polymorphic extra systoles with different shapes
- Impact on ECG patterns
