the claim

Premenstrual syndrome is associated with a higher resting heart rate.

the verdict
CONTESTED PARTIAL
Recorded sources
2 sources for · 1 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that premenstrual syndrome is associated with a higher resting heart rate?

Partly. One cited study reports higher resting heart rate in women with PMS during the late-luteal phase, and a small study found a tendency toward higher resting heart rate in the luteal phase, but the same source notes failed replications and another study links greater PMS symptom intensity to higher heart rate variability, which points the other way. The evidence covers only parts of the claim and is inconsistent.
