Wireless network for electrocardiography

The incidence of cardiovascular diseases is rising, so more people are requiring cardiac services. The private service is very expensive; hence the public health sector is exceeded by their capacity to accomplish this demand. The proposal to solve this problem is the implementation of a wireless network based on Bluetooth (BT) for recording, monitoring and analysis of electrocardiographic signals (ECG). Three surface electrodes are placed on the chest following standardized points of triangle of Einthoven. The signals measured by electrodes are carried to Arduino UNO card, which works as an instrumentation amplifier. Then ECG signal is sent by BT from Arduino Uno to a mobile device carried by the user, so he can send it to a workstation where the ECG is processed or analyzed by an expert. This proposal would help the health sector to improve the quality of their service in the care of patients with heart diseases; also costs of care would significantly decrease.
