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.
Uses of ECG / EKG. The electrocardiogram (ECG or EKG) is a noninvasive routine examination of the electrical activity of the heart that is used to reflect underlying heart conditions. Regular heart movements are controlled by a complex set of electrical impulses that direct the upper and lower heart chambers to contract and relax rhythmically.
