Abstract
In our preliminary study, we proposed a wearable, power-proficient and multichannel ECG device, so-called wECG, aiming at real-time ambulatory cardiac monitoring. This paper targets the validation of wECG device using a reference system. The collected ECG signals from the developed device have been benchmarked with those from Polysomnography (PSG) system under exercising condition following a Bruce-based protocol. Compared to current ECG monitors, the proposed wearable ECG system can provide significant improvements in terms of device mobility, system inerrability, monitoring duration and signal quality. These improvements will enhance critically the home-based diagnosis and treatment of chronic cardiac disorders such as arrhythmia and atrial fibrillation. Keywords

Cardiovascular diseases
Introduction
Cardiovascular diseases have become social and economic burdens as it is among the primary sources of mortality in the world. The World Health Organization (WHO) assessed that 17.5 million individuals died of cardiovascular disorders in 2008 and the mortality rate is predicted to reach consistently 23 million in 2030 [1]. Fortunately, consequences caused by cardiorespiratory disorders are avertable thanks to early diagnosis, prediction and promptly intervention [2]. Ambulatory Electrocardiogram (ECG), so-called Holter ECG, have been considered as crucial tools for the long-term monitoring and detection of cardiovascular disorders [3, 4]. wECG is a new wireless wearable device, which targets long-term ambulatory ECG recording under various normal

and exercising conditions. The device cooperates with a smartphone and allows the measurement of up to 7 ECG leads including 3 bipolar limb leads, 3 augmented unipolar limb leads and 1 unipolar chest lead. The recorded signals will be transmitted to the smartphone via the Bluetooth Low Energy (BLE) protocol and stored on the online database. The wECG device was designed to comply with the medical general standard IEC 60601-1. The aim of this work was to verify the accuracy of the ECG signals from the wECG compared to the signals collected from an FDA approved system-ALICE 5 from Philips. Multiple ECG characteristic features corresponding to physiological parameters include QRS amplitude, QRS time delay, and the heart rate were estimated from ECG signals collected from a Bruce-based data collection protocol. Also, other designed characteristics including Bluetooth communication parameters (i.e., connection interval (CI), connection latency, and sending package size) and power consumption parameters (i.e., average power consumption and maximum battery life) were also tested.
