About

This study aims at recording cardiac arrhythmias in patients after open heart surgery. The arrhythmias will be monitored during the entire first postoperative period, till six weeks after surgery.

Full description

Approximately 30-50% of patients after cardiac surgery develop cardiac arrhythmias, most often atrial, and most frequently atrial fibrillation (AF).

Various risk factors, inter alia, the type of surgery itself are risk factors. The major additional risk factors for postoperative atrial fibrillation are: age, valvular involvement, length of cardiopulmonary bypass and cross-clamp times.

Postoperative atrial fibrillation is associated with increased length of stay, higher morbidity and mortality including stroke.

Documentation of postopertive atrial fibrillation is well gathered during the postopertive length of stay, but scarce information exists regarding the development and occurence of atrial arrhythmias after the patient's discharge.

Additionally, the various management protocols which exists with regard to postoperative atrial fibrillation, rely on continuous treatment of the patients with amiodarone or various other anti-arrhythmic agents for the initial postoperative period, and the initial first month after discharge.

So far there is not an unambiguous recommendation regarding the duration of treatment required with amiodarone after releasing the patient.

The aim of this study is to document and record cardiac arrhythmias in patients after open-heart surgery within the time window since the release from hospital and up to six weeks after surgery.

Results of the study will allow us to fully characterize postoperative arrhythmias and their risk factors.
