The reason for having a 24-hour ambulatory electrocardiogram (EKG) before atrial fibrillation surgery is that it can clarify the nature of atrial fibrillation, the frequency of episodes, and the duration of the episodes.
The 24-hour ECG can understand the electrical activity of the patient within 24 hours, and for patients with atrial fibrillation, it can understand whether the frequency of atrial fibrillation is occasional or frequent, whether the duration of the attack is minutes or hours, and whether it can assist in determining whether it is combined with other arrhythmias such as atrial flutter, etc. The necessity of surgery and the expected efficacy of surgery can be assessed through the test, and the decision of surgery can be made by combining with other auxiliary tests. This test can be used to assess the need for surgery and the expected outcome of the patient, in combination with other ancillary tests.
Before atrial fibrillation surgery, in addition to the dynamic electrocardiogram, it is also necessary to improve the blood routine, blood biochemistry, coagulation function, infectious disease series, chest radiographs, cardiac ultrasound, etc., in order to fully understand the patient’s situation and assess the risk of surgery to decide whether to operate.
