Heart contraction when I sneeze? Normal?

I’ve suffered from allergies for years without end now. I usually take pills if my eyes are swollen or I’m just really affected but sneezing and throat itch is the law in the mornings now. I’ve heard of people being allergic to the cold but I also live in a place with lots of allergens so I’m not worried.

I have noticed that most of the times I sneeze my heart does some type of contraction. It’s like it shakes a bit, some times I can even feel it for a few seconds after I sneezed... I don’t know if this is happening because I sneeze so much or if there’s other alarming reason, does anyone else experience this? 😬
