Error re heart rate
'During inspiration vagal tone is slowed down and the heart rate goes up (being maximal at the peak of inspiration), while during expiration vagal tone is increased and heart rate decreases, being slowest at end-inspiration.'

I feel reasonably confident that this is backward; heart rate becomes slowest at end-expiration, not end-inspiration. A quick search of the literature agrees.

I'll wait a week in case someone sees something I don't there, and then correct it. eggsyntax (talk) 23:21, 2 October 2023 (UTC)
