Thanks for the concern. This may actually be a completely normal response called sinus arrhythmia
, in which the regular contraction of the heart varies slightly with a more prolonged pause
related to breathing. As long as you don't have other concerning symptoms such as sustained palpitations, chest pressure, lightheadedness
, etc, I would not worry excessively.
Hope this helps, wish you the best health,
