Formula

HR * SBP

How it is used

• RPP = HR × SBP, a bedside index of myocardial oxygen demand.
• Rate and pressure raise demand together, so in ischemia aim to lower both: treat pain and anxiety, and use beta-blockade when it is not contraindicated.
• There is no fixed normal: follow the trend in the same patient.
