P wave morphology in guiding the ablation strategy of focal atrial tachycardias and atrial flutter.doi:10.2174/1573403x10666141013121252Justin M S LeeSimon P FynnBentham Science Publishers
144 Type I flutter, with negative P waves in the inferior leads, results from a circulating wavefront that passes around the tricuspid valvar orifice and up the terminal crest in a counter-clockwise direction. The hinge of the tricuspid valve forms the anterior boundary, while the posterior ...
3 4 When it occurs, atrial flutter compromises haemodynamics, reduces exercise tolerance, and is often resistant to medical treatment. The P wave has been found to change its electrical characteristics before atrial fibrillation supervenes in patients with coronary artery disease.5 We sought to study...
1. P wave: saw-toothed "flutter" F waves2. Atrial rhythm: regular3. Atrial rate: 250 to 350 beats per minute4. PR interval: not measurable5. Ventricular rhythm: usually regular6. Ventricular rate: depends on degree of AVblock. Can be 2:1, 4:1, etc.7. QRS complex: usually within...
Characteristic findings in the ECG (absence of the P-wave, irregular atrial oscillations replacing the P-waves, and the irregular ventricular response) permit a reliable diagnosis of atrial fibrillation it, most cases. The morphology of f-waves (fine or coarse) seems to be of little clinical re...
The flutter group showed prolongation of the mean right intra-atrial conduction time at 50 msec (control of 37 msec, P less than 0.05), the mean interatrial conduction time at 92 msec (control of 44 msec, P less than 0.001) and the mean P wave duration at 132 msec (control of 112 ...
摘要: ObjectiveTo assess the risk of atrial fibrillation (AF) recurrence after elective cardioversion of AF in relation to the signalaveraged P wave duration (SAPWD), clinical characteristics of the patient, and the duration of the AF disease.关键词:...
