Breath-holding study suggests irregular heartbeats can be hard to reproduce
Although heart rate and blood pressure readings from breath-holding tests are usually reliably accurate, another vital measurement could be missing a beat, a University of Alberta study shows. Looking at whether a person's heart and blood vessels react the same way every time they hold their breath while low on oxygen, researchers were surprised to discover that arrhythmias—irregular heartbeats—occurred only some of the time, which may make them harder to predict than previously assumed.
