Racing heart after eating

Hello,

The last two nights I've eaten late dinners due to being so busy ( about 8:30pm ), afterwards ( 5-10 minutes ) my heart starts to feel like its racing, ive checked my heart rate, it doesn't go above 80, and I can feel it beating harder than normal, I know that the heart beats faster to help blood flow after eating so your stomach can digest the food, etc. Ive recently been put on Zoloft for Anxiety, which has caused my heart rate to be lower than normal ( normally 74-88 bpm, now 55-70 bpm, averages at about 60 bpm ) so im not sure if it just seems like it because my heart rate has slowed, and that's how I can tell that it is beating faster, or if it is just because ive eaten heavy meals ( first night it was 80 degrees so I had sandwiches, second night it was spaghetti ). Just wondering if anyone else has gone through this and if you can give me any kind of insight, thanks.

Those rates are pretty good tbh and up into the 90s is still considered normal during digestion. Really don't worry a heart rate 40-80bpm is perfectly normal and the heart will adjust to lots of things like hormones, time of day, eating, meds etc... so varies greatly. In fact heart rate variation is the sign of a very healthy heart indeed! The fitter the person and better the heart the more variation you see.
