The electrocardioscope uses an Android tablet or smartphone as a wireless terminal for viewing the electrocardiograms. The project involves skillfully combining a small PIC interface to control an analog input stage with a great deal of software.
Making use of technology first invented by Willem Einthoven, we’ve developed an application that’s instructive, fascinating and potentially useful to everyone. Traditionally, electrocardioscopes are cumbersome, frail machines energized from conventional AC power outlets. Being able to perform your own electrocardiograms allows you to monitor the mechanical function (and possible dysfunctions) of a heart. An excellent tool for anyone interested in monitoring their personal health or developing a greater understanding of human biology or cardiology.
We’ve released an ECG interface in the form of a ready-to-use module which only requires the addition of four electrodes and an Android application (for smartphone or tablet). As it uses Bluetooth communication, there’s no physical connection between this terminal and its interface.
