Abstract	The phenomenon of aging populations has produced widespread health awareness and magnified the need for improved medical quality and technologies. Statistics show that ischemic heart disease is the leading cause of death for older people and people with reduced mobility; therefore， wheelchairs have become their primary means of transport. Hence， an arrhythmia-detecting smart wheelchair was proposed in this study to provide real-time electrocardiography （ECG）-monitoring to patients with heart disease and reduced mobility. A self-developed， handheld ECG-sensing instrument was integrated with a wheelchair and a lab-written， arrhythmia-detecting program. The measured ECG data were transmitted through a Wi-Fi module and analyzed and diagnosed using the human–machine interface. The ECG-monitoring hardware of this system differed from the conventional adhesive-pad designs and adopted metallic， touch-sensitive copper balls on the wheelchair armrests for detecting the ECG signals. The raw signals were filtered， amplified， and extracted as refined ECG signals， which were then wirelessly transmitted through a microcontroller unit （MCU） and Wi-Fi module. In the arrhythmia-detecting software function， the P-wave and R-wave ECG signals， which are related to the sinoatrial node， were analyzed and assessed for signs of arrhythmia using the written software program. LabVIEW was adopted for the HMI in this system to incorporate a Windows working environment. The functional displays in the designed interface were also customized according to the needs of patients and health professionals. To demonstrate the practical value of this study， participants with normal and abnormal heart rhythms were separately examined to verify that the proposed system yields accurate measurements，is convenient to use and inexpensive.
