Valsalva Maneuver's Effect on Heart Rate
Robert Parati and Ashley Moretti
Research over the usage of the Valsalva maneuver had been previously tested while recording its affect on arterial pressure. With the forced exhalation on a closed glottis, the maneuver increases the blood pressure as long as it is being performed. The maneuver has been used for years by weight lifters but has not been deeply investigated until the past few decades. With many hospitals using the exercise for post cardiac patients, much was to find out about its affect on the heart. In the experiment one group was given the instruction on how to properly perform the maneuver and one group was not. Then data was recorded on their heart rate while lifting 40% of their body weight.
