Do y’all ever get slight heart palpitations after a heavy night of drinking?

My Physician did some tests, ECG showed slight irregularities, she contributed this to me being dehydrated. This happened last week, I had like 10 beers the day before & woke up with skipping beats, almost feels like your heart stops beating for a second, then beats again a little harder. I don’t drink that much anymore, usually 2-3 Coors lights a night. I do drink around 100oz of straight water a day too, but I am heavy, 5’9 290lbs, maybe drink more water? Do you guys drink Electrolytes powders like those Liquid Iv ones? Pedialyte did help after that Dr visit, she said drink electrolyte drinks but NOT high sugar like Gatorade.
