The mean arterial pressure is a term used in medicine to describe an average blood pressure for an individual. It is defined as the average arterial pressure during a single cardiac cycle. Usually, blood pressure is assessed with multible heart cycles at least for a minute, and that would then include the heart rate.
The etiolgy of a serious valve disorder would be to reduce the cardiac output (CO is stroke volume for each heartbeat times heart rate). Under other physiological conditions, there would be an increase in heart rate and increased blood pressure. "Increased HR leads to increased cardiac output, among other things, which increases blood pressure".
Hope this helps and if you have any further questions or comments, you are welcome to respond. Thanks for the question, take care.
I think maybe you need to be a little more specific with your question. I am curious as to what is going on with you that you are asking this question. What did the doc say or the tests show? What symtoms were you having, are you on meds? A little more info would be pretty helpful.................................
