Engineers published a model for creating a 3D-printed optical cardiograph

Nowadays, the most common way to diagnose arrhythmia is a violation of a number of interrelated

intracellular processes in the heart - is optical mapping. However, its use is limited due to the high cost of equipment and difficulties in processing the recorded signals.

To reduce the cost of this method of diagnosis, scientistshave developed a 3D-printing apparatus for optical mapping, which will allow to record electrical excitation and changes in intracellular calcium concentration.

It was important to us that the software was accessible toused by physiologists, who often may not have sufficient technical skills to program in, for example, C++. In addition, our device gives you the freedom to do new experiments with different types of samples.

Earlier, Chinese scientists from Shanghai University of Transport have developed a pacemaker that will be charged from a heartbeat.
