Premature Atrial Contractions

Atrial Premature Contractions Arising from the Right Atrial Appendage

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...

Symptomatic Bradycardia Caused By Premature Atrial Contractions Originating From Right Atrial Appendage

Premature atrial contraction is a common form of supraventricular arrhythmias. In rare cases, severe symptoms other than palpitation may occur. In this report, we present a patient with symptomatic bradycardia which developed secondary to blocked premature atrial contractions and was successfully treated with radiofrequency ablation.

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...
