Heart beats fast and thumping after drinking alcohol, should I be concerned?

Possibly. What kind of alcohol? Wine, beer, spirits? How much alcohol? Are you taking any medications? Any health issues? Tannins in wine can cause heart rate changes. Bing drinking does adversely affect the heart. Too much alcohol can cause heart muscle disease. Discuss your drinking habits with your doctor to determine if any additional evaluations are necessary.
PLEASE KEEP . Extra well hydrated when you drink. The amount of alcohol makes a difference too so keep the amounts low.
