Unless resuscitative efforts are begun immediately, cardiac arrest leads to death within a few minutes. This is often referred to by doctors as sudden death or sudden cardiac death (SCD)..
Parameter (units) Definition. Heart rate (beats/min) Number of ventricular contractions per unit time. Stroke volume (ml) Volume of blood ejected from the left ventricle with each contraction. Cardiac output (litre/min) Volume of blood ejected from the left ventricle over unit time. Cardiac output = stroke volume x heart rate. Stroke index (litre/m2) Stroke volume related to the size of the individual. Stroke index = stroke volume/body surface area. Cardiac index (litre/min/m2) Cardiac output related to the size of the individual.
