Objective: With the development of ECG monitoring systems, the diagnosis of cardiac arrhythmias is improved significantly. Here, we introduced our experience with another new long-term ECG patch device (Smartpatch II) for monitoring the cardiac arrhythmia.

Method: This device was applied to patients complained with a history of chest pain, palpitation or syncope and admitted to the 3 medical centers between April 13, 2017 and October 18, 2017. Patients wore both 24-hour Holter monitor and the Smartpatch II on the first day. On the second day, the 24-hour Holter monitor was removed and patients continued to wear the Smartpatch II up to 7 days. All ECGs were analyzed by 2 experienced independent observers.

Results: A total of 101 patients (mean age: 57.5 ± 15.4 years, 52.5% male patients, body mass index: 24.0 ± 2.9 kg/m²) were included. Over the first 24 hours, Both the Smartpatch II and Holter monitor documented 36 events. The sensitivity and specificity of Smartpatch II was 100% (95% CI, 90.3%, 100.0%) and 100.0% (95% CI, 94.5%, 100.0%) respectively when compared with Holter monitor on the first day. Over the total 7 days of monitoring, Smartpatch II detected significantly more arrhythmic events than one day recording (59 (58.4%) versus 36 (35.6%), p<0.001).

Conclusion: Over a total wearing time of 7 days, the patch device detected more cardiac arrhythmia than 24- hour monitoring.
