Abstract

Background: Basedow is associated with many arrhythmias. Some of these disorders, such as atrial fibrillation (AF) can be the cause of thrombosis, embolism, and death in Graves' patients. Objectives: Describe the characteristics of arrhythmia and some related factors on 24-hour Holter monitoring in Graves' patients at Bach Mai hospital. Methods: We performed a descriptive study on 62 patients with Graves. Clinical, biochemical and therapeutic characteristics were collected from the medical records. 24h Holter monitoring was performed for all patients. Results: Mean age was 41.3±17.1 years old; male rate 40.3%, mostly new cases Basedow (58.1%). All patients had laboratory hyperthyroidism (mean FT4: 67.1±64.5pmol/l; mean TSH 0.009±0.005µU/ml). On 24h Holter 24h monitoring: average heart rate was 90.1 ± 16.2 beats/min; Atrial fibrillation 82.3%, sinus tachycardia 83.9%, atrial fibrillation 16.1%, atrial flutter 1.6%, paroxysmal supraventricular tachycardia 3.2%; ventricular ventricular failure 11.3%; Unsustainable ventricular tachycardia 6.5%. The rate of atrial fibrillation was statistically significantly higher in patients ≥ 60 years old, FT4 grade ≥ 100pmol/l; TSH < 0.005 µU/ml, TRAb > 20IU/L. Conclusion: Hyperthyroidism increases heart rate and can cause arrhythmia, mainly atrial fibrillation. This complication is more common in elderly patients, with high FT4 and TRAb levels, and low TSH.
