Fibrillation is random inffectual contractions of the heart wall. It is called atrial fibrillation when it's in the upper chambers, and ventricular fibrillation when in the lower chambers of the heart.
Cardiac Fibrillation (fibrilla = little fibers [referring to muscle fibers]) can be either atrial or ventricular. In either case, it is extremely rapid, incomplete contractions resulting in irregular pressure and uncoordinated movement of the heart. Atril fibrillation can be a chronic condition, but unless stopped, the venticular form is fatal.
Tachycardia (tachy = rapid + card = heart + a = noun form) is a heart rate that exceeds normal range. Higher heart rate equals a less efficient pump and less blood flow to the rest of the body leading to increased work and oxygen demand by the heart tissue.
It is called the cardiac cycle.The contraction phase of the heart is called Systole and the relaxation phase is called Diastole.
Systolic means pertaining to systole, or the contractile phase of the cardiac cycele.
