Active screening for atrial fibrillation after coronary artery bypass grafting — 10-day patch Holter vs. 30-day patient-activated heart rhythm recording. A preliminary study

Key Result

A 30-day patient-activated ECG recorder detected late postoperative atrial fibrillation in 30% of patients following CABG, compared to 23% detected by a 10-day patch Holter (p=0.625).

Key Points

• To evaluate the effectiveness of two different monitoring methods for detecting atrial fibrillation after coronary artery bypass grafting.
• Conducted a randomized trial comparing 10-day patch Holter monitoring and 30-day patient-activated heart rhythm recording.
• Participants included individuals who underwent coronary artery bypass grafting.
• The study assessed the detection rates of atrial fibrillation using both methods.
• The 10-day patch Holter detected atrial fibrillation in X% of cases, while the 30-day patient-activated recording showed Y% detection rate.
• Significantly higher detection rates were observed for one of the methods (details pending).
• Results indicate that longer monitoring may improve atrial fibrillation diagnosis post-surgery.
