Thulasi Bai and SK. Srivatsa of the Sathyabama University in Tamil Nadu (India) have developed a wearable cardiac telemedicine system that allows post-cardiac patients renewed mobility. Thulasi Bai’s prototype Bluetooth heart monitor records periodically an electrocardiogram (ECG) and transmits the information through radio frequency signals to the patient’s cell phone. The modified phone has an added analyzer circuit that checks the ECG signal for signs of imminent cardiac failure. If errant signals are detect, like any arrhythmia, the cell phone alerts the patient and transmits a sample of the ECG signal to the nearest medical care centre, via the SMS text service, together with patient details. Now researchers are working on how to enable global-positioning system, GPS, in the modified cell phone, so that the medical centre can more quickly pinpoint the patient.
