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.
Electrocardiogram, abbreviated as either EKG or ECG, is used to record the heart's electrical activity. The EKG is a valuable tool for doctors, as it can help diagnose heart problems, like heart attacks, arrhythmia and heart failure. Besides identifying heart problems, an EKG can also show how fast the heart is beating, whether the heart's rhythm is steady or irregular and the strength and timing of its the electrical signals.
