Factors regulating ventricular rates during atrial flutter and fibrillation in pre-excitation (Wolff-Parkinson-White) syndrome.
Key Result
The functional properties of the accessory pathway determine ventricular rates during atrial flutter and fibrillation in patients with Wolff-Parkinson-White syndrome.
Key Points
- To explore how accessory pathway properties influence ventricular rates during atrial flutter and fibrillation in patients with WPW syndrome.
- Conducted premature atrial stimulation and His bundle recordings in 6 patients with WPW syndrome.
- Assessed ventricular rates triggered by earliest impulses during atrial flutter and fibrillation.
- Ventricular rates were influenced by the functional properties of the accessory pathway.
- Differences observed in ventricular responses among patients based on accessory pathway characteristics.
