Background: Atrial fibrillation is a frequently observed arrhythmia that can cause cardiogenic cerebral embolism. However, the rate of detection of atrial fibrillation through 12-lead electrocardiography (ECG) or 24-h Holter ECG monitoring is low. Herein, we reported two cases in which we could detect paroxysmal atrial fibrillation using a patch-type long-term ECG recorder that can record continuously for≤14 days.
Case 1: An 83-year-old man with a current history of hypertension, and atrial septal defect had become aware of palpitations. Although the 24-h Holter ECG did not detect arrhythmic events, long-term Holter ECG monitoring successfully recorded the evidence of symptomatic paroxysmal atrial fibrillation.
Case 2: A 58-year-old man underwent a regular health checkup at his workplace, and atrial fibrillation was detected. Although the 24-h Holter ECG did not capture any arrhythmic events, long-term Holter ECG monitoring successfully provided diagnostic evidence of asymptomatic paroxysmal atrial fibrillation.
Conclusion: Long-term Holter ECG monitoring may improve the clinical management of patients suspected of having cardiac arrhythmia diseases.
