Relationship between SV, HR, and Q

• Heartbeat


  one contraction and relaxation of the heart muscle
• Heart rate (HR)?

  The number of times the heart contracts per minute
• Stroke volume?

  Amount of blood ejected from left ventricle with each heartbeat (ml/beat)
• Cardiac output (Q)?

  Amount of blood ejected from the left ventricle of the heart per minute.

  Q = SV x HR  (L/min)
