Large differences in timing of contractions can reduce cardiac efficiency and is correlated with heart failure.FludrocortisoneShort QT syndromeMulticenter Automatic Defibrillator Implantation Trial: Multicenter Automatic Defibrillator Implantation Trial and MADIT II are implantable cardioverter defibrillator (or ICD) trials which investigate whether prophylactic ICD therapy in moderately high-risk coronary patients (in addition to conventional therapy) would significantly reduce death compared with patients treated with conventional therapy alone.Interbeat interval: Interbeat interval is a scientific term used in the study of the mammalian heart.Sick sinus syndromeGyromancy: Gyromancy is a method of divination in which a person spins around inside or walks the circumference of a circle drawn on the ground, the perimeter of which is marked with the letters of an alphabet.

These reflexes are absent due to the development of the frontal lobes as a child transitions normally into child development.Trendelenburg position: In the Trendelenburg position, the body is laid flat on the back (supine position) with the feet higher than the head by 15-30 degrees, in contrast to the reverse Trendelenburg position, where the body is tilted in the opposite direction.
