| atherosclerosis | buildup of fibrous plaques of fatty deposits & cholesterol on the inner walls of the coronary arteries |
| baseline | the flat horizontal line that separates the various waves of the ECG cycle |
| cardiac cycle | one complete heartbeat |
| dysrhythmia | an irregular heart rhythm; alter termed arrhythmia |
| electrocardiogram | the graphic representation of the electrical activity of the heart; known as ECG (or EKG) |
