Premature Atrial Contractions in the General Population

Premature atrial contractions in the general population: frequency and risk factors.

BACKGROUND Premature atrial contractions (PACs) are independent predictors of atrial fibrillation, stroke, and death. However, little is known about PAC frequency in the general population and its association with other cardiovascular risk factors. METHODS AND RESULTS We performed a cross-sectional analysis among participants of the population-based Swiss cohort Study on Air Pollution and Lun...

Premature Atrial Contractions Managed With Slow Pathway Ablation

We present data from 18 year old male patient referred to our clinic for evaluation and treatment due to persistent premature atrial contractions (PAC). Up to the time of admission, the patient never experienced paroxysmal tachycardia, and his principal complaint was the irregular heart rhythm refractory to all types of antiarrhytmic drug therapy. Electrophysiological study was performed and it...

Obstructive respiratory events and premature atrial contractions after cardioversion.

Recurrence of atrial fibrillation (AF) after electrical cardioversion (ECV) is increased in patients with obstructive sleep apnoea (OSA). In patients with persistent AF, with (n=40) and without (n=32) obstructive respiratory events (OREs) during sedation for ECV, we determined the occurrence of premature atrial contractions (PACs) before and after insertion of a nasopharyngeal tube. The influen...

Automatic Detection of Conducted Premature Atrial Contractions to Predict Atrial Fibrillation in Patients after Cardiac Surgery

A method was developed to automatically detect conducted Premature Atrial Contractions (PACs) from the ECG signal. The method consisted of identifying the R waves of the ECG signal, determining the irregular beats that correspond to premature beats and dissociating atrial and ventricular premature beats. The method was developed using the ECG signals from Physionet and Cardio-Vascular Intensive...
