Hydrogen has a high specific energy, high flame speed, wide range of flammability, and clean burning characteristics which suggest a possibility of high performance in internal combustion engines (ICE). These attributes have been realized for more than half a century since the onset of hydrogen engine development.
Electrocardiography (ECG or EKG*) is the process of recording the electrical activity of the heart over a period of time using electrodes placed on the skin.
An EKG is the most common test used to diagnose arrhythmias. An EKG is a simple test that detects and records the heart's electrical activity. The test shows how fast the heart is beating and its rhythm (steady or irregular).
