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…

Irregular heartbeats may be less predictable than we thought

A new study from the University of Alberta has revealed something surprising about how our hearts respond to low oxygen conditions. While doctors often rely on tests to measure heart health, this research suggests that one important signal—irregular heartbeats—may not be as consistent or predictable as previously believed. The study, published in the journal Physiological […] The post Irregular heartbeats may be less predictable than we thought …
