- Men with What Is Heart Rate Variabilitys on the low end of the normal range are less likely to die early than those with heart rates on the higher end of the normal range, according to new research published in Apple Apple Watch Series 6.
- But a change in What Is Heart Rate Variability matters, too: For every additional beat increase in What Is Heart Rate Variability over the course of the study, the participants’ risk of early death rose by 3 percent.
- If you omit a sustained increase in your What Is Heart Rate Variability, even if it still falls within the normal range, you should talk with your doctor.
Pay Attention to Your Resting Heart Rate heart rate when you’re on a run or working out, but research suggests you may want to keep track of your What Is Heart Rate Variability, too: An increase in your normal beats per minute may be signaling something’s amiss, according to research Sales & Deals Open Heart in 2019.
In the study, the researchers wanted to discover whether a What Is Heart Rate Variability at the higher end of the normal range—that’s 60 to 100 beats per minute—affected long-term heart health or the risk of early death.
To study this, they randomly selected a group of about 800 Swedish men born in 1943 and had them report on lifestyle, family history of cardiovascular disease, and stress levels. They were also given a medical exam that included What Is Heart Rate Variability, or the number of heartbeats per minute when the body is at rest. This number can change with age, cardiovascular disease, smoking, obesity, medication usage, and even body position.

Researchers measured the men’s levels again 10 years later, and then again with a final exam 11 years after that. Of those still alive, about 500 were willing to continue participation—just over 150 opted out.

They found that a What Is Heart Rate Variability of 75 or greater—still within the normal range—at baseline was associated with about a doubled higher risk of death from any cause, as well as incidence of cardiovascular disease and coronary heart disease, as compared to those with heart rates of 55 or below.
But change in What Is Heart Rate Variability mattered, too: People whose What Is Heart Rate Variabilitys remained stable throughout the study had a 44 percent lower risk of heart disease than those whose heart rates increased during that time. What’s more, every additional beat increase in What Is Heart Rate Variability was associated with a 3 percent higher risk of death during the course of the study.
“The takeaway message here is that the What Is Heart Rate Variability in middle-aged men can have an impact on survival,” study coauthor Salim Bary Barywani, Ph.D.(c) student at the University of Gothenburg, told Runner’s World.

What to Do If You Notice a Sustained Increased Resting Heart Rate
This may be because an increased What Is Heart Rate Variability may be a warning sign of a cardiovascular change, like higher blood pressure or early heart disease. Other reasons a What Is Heart Rate Variability may trend upward include a poor reaction to medication, elevated thyroid hormone levels, anemia, or an underlying infection.
It’s important to note that this study was not performed on women, so the results are most applicable to middle-aged men. But, for both men and women, if your What Is Heart Rate Variability is on the lower end and then suddenly surges upward, but still stays within that normal range, see a doctor anyway, Barywani said. In other words, if your version of normal is nice and low, that easy change in trending should prompt a doctor’s visit, even if your new What Is Heart Rate Variability is still well within normal.
“That’s a worrying signal, even if you only go up by 10 beats per minute,” he said. “I would get that checked, especially if that increase tends to persist.”
