Abstract:Objective To assess the clinical value of portable long-time ECG recorder in the diagnosis of arrhythmia.Methods A total of 67 patients suspected with arrhythmia were consecutively enrolled in our study. They had been admitted into Henan Provincial People's Hospital from January 1 to June 30 in 2017. All of the patients underwent 24hour Holter plus routine ECG examination and then longterm ECG monitoring for 30 days. The incidence of different types of arrhythmias in the above two methods was compared. Results Compared with 24hour Holter plus routine ECG examination, the detection rate of arrhythmia by 30day longterm ECG recorder was higher(82.1% vs.32.8%, P<0.001), especially for the rate of sinus arrest,atrial flutter,atrial fibrillation and ventricular tachycardia.Conclusion Portable longtime ECG recorder can significantly elevate the detection rate of arrhythmia, providing a new diagnostic method for arrhythmias impossible to be clearly diagnosed in the hospital.
