Thus the measurement of acceleration should be considered while considering the reliability of the estimate of heart rate reported by the automated algorithm. In [17], a study is performed on the use of wearable devices for monitoring the patient movement. From analysis of simultaneous traces of ECG and acceleration signals shown in [17], we conclude that the motion artifacts are generated in the ECG signal when there is an abrupt and significant change in the acceleration signal due to patient ambulation.

85]) For further amplification and filtering of ECG signals more often INA is followed by a LPF (lowpass filter). This lowpass filter is an active filter made by on-chip opamps or OTAs (operational transconductance amplifiers) and discrete resistors and capacitors. 1. However it can be programmable. The overall gain of the analog ECG signal conditioning module is also programmable, usually in the range of 200 to 1000. Wearable ECG recorders are often interfaced with personal computers, mobile phones or removable memory cards through USB (universal serial bus), IrDA (Infrared interface) or RS232 ports [136].

3 Hardware Development of Wearable ECG Devices* Maryam Shojaei Baghini, Dinesh K. Sharma and Rakesh K. Lal, Department of Electrical Engineering, IIT Bombay, India. 1 Introduction Personal healthcare devices find many applications where noninvasive monitoring of biopotential signals is required. Among physiological parameters ECG (Electrocardiogram) is one of the most important vital signals because it directly reflects the heart condition. Wearable devices used for recording ECG related information may continuously record heart rate and/or ECG for several hours or days and store it on the system memory.
