How Will The Cardiac Output Change If You Double The Heart Rate But Reduce The Stroke Volume By One-Half?. Co is the product of heart rate (hr) by stroke volume (sv), the volume of blood. Svs are also used to calculate.

Co is the product of heart rate (hr) by stroke volume (sv), the volume of blood. Cardiac output is the volume of blood pumped by the heart per minute (measured in litres per minute, l/min). Svs are also used to calculate.
