How do you calculate double product?
The double product was calculated by multiplying SBP by HR (mmHg/min).
What is double Product exercise?
The double product is the product of the heart rate and systolic blood pressure. The double product break point (DPBP) is a physiologic threshold that occurs at similar exercise intensities to that of the ventilatory threshold (VT).
What is the normal range for peak RPP?
|High||more than 30000|
|High Intermediate||25000 – 29999|
|Intermediate||20000 – 24999|
|Low Intermediate||15000 – 19999|
What does it mean when a stress test is positive?
Positive or abnormal: Doctors may conclude the stress test is positive for cardiac ischemia—meaning the heart muscle wasn’t getting adequate oxygenated blood during the stress. There are certain ECG and imaging changes that would support this conclusion. There are also clinical findings that could support it.
What if the pulse pressure is high?
Managing your pulse pressure is important because a higher pulse pressure means your heart is working harder, your arteries are less flexible or both. Either of the two increases your risk of heart and circulatory problems, especially heart attack or stroke.
What is RPP stress test?
The rate-pressure product (RPP) was calculated as the product of heart rate and systolic arterial pressure for both baseline and maximum measures. The difference between the RPP max and the basal RPP is known as the RPP reserve.
Does Double Product increase during exercise?
On average, the break-point of double product was 6.6 min (56 watts). These results clearly showed that the break-point of double product with an increase in workload appeared even though the workload was relatively low.
What is the target heart rate in a stress test?
During your cardiac exercise stress test, you’ll walk on a treadmill or cycle on an exercise bike until you reach your “target heart rate”- which is 85% of the maximum heart rate predicted for your age. Every 3 minutes, the speed, incline and resistance of your treadmill or bike will increase, up to 15 minutes maximum.
