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.
What is an EKG? An electrocardiogram or EKG, records electrical activity in the heart. An machine records these electrical signals across multiple heart beats and produces an EKG strip that is interpreted by a healthcare professional.
