Prediction of the recurrence of atrial fibrillation after successful cardioversion with P wave signal-averaged ECG.

Background: The recurrence of atrial fibrillation (AF) was often observed after cardioversion.

Prediction of Conversion from Paroxysmal to Permanent Atrial Fibrillation

Background: Paroxysmal atrial fibrillation (PAF) transits to permanent atrial fibrillation (PEAF). The current study was to determine whether a P wave‐triggered P wave signal averaged electrocardiogram (P‐SAECG) and chemoreflexsensitivity (CHRS) are useful to predict a conversion to PEAF in patients with PAF.

Prediction of Atrial Fibrillation with Atrial Late Potentials and Pathological Chemoreflexsensitivity

Background: Atrial fibrillation (AF) is a very common arrhythmia that often causes the serious complication of a stroke.

day after CABG. Results: postoperative AF was observed in 37 (37%) of 101 patients. Patients with AF were older (68.4 -4- 6.9 vs. 63.8 -4- 9.4 years, p < 0.01) and had a significantly lower CHRS (3.32 4- 1.83 vs. 4.17 4- 2.19 ms/ram Hg, p < 0.05). The predictive power for a pathological CHRS achieved a specificity of 63%, a sensitivity of 60%, a negative predictive value of 73%, a positive predictive value of 48% and an accuracy of 61%. Patients with postoperative AF stayed longer in the intensive care unit (2.9 4- 1.7 vs. 1.3 4- 0.5 days, p < 0.0001) and in hospital (13.5 4- 4.3 vs. 11.4 4- 1.1 days, p < 0.0004). Conclusion: the results of our study show that the risk for AF after CABG could preoperatively be predicted with an analysis of CHRS. The predictive power of a pathologic CHRS could be used for a preoperative risk stratification.
