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.
ECG is the recording of the electrical activity of the heart from electrodes placed on the surface of the body. Many cardiac arrhythmias are episodic in nature, especially in the cat. This means that some rhythm or conduction abnormalities can be missed during a standard 1-minute ECG recording.
