Although electrocardiograms (ECGs) can help predict cardiac emergencies as much as several months before a potentially life-threatening episode, this usually requires being hooked up to an ECG machine for a period of time at a doctor's office or hospital. A new sensor belt prototype allows an ECG to be recorded around the clock for up to six months, increasing the chances a problem will be discovered and treated before an emergency strikes.
Electrocardiograms (ECGs) non-invasively measure the heart's electrical conduction system using electrodes attached to the skin. In this way, they are able to measure heartbeat rate and regularity over time. The sensor belt, developed by researchers at the Karlsruhe Institute of Technology (KIT) in Germany, is able to do this continuously over a very long period and also measures breathing frequency and activity.
