Hello and thank you for using HCM.I carefully read your question and I understand your concern.You shoud not worry.I will try to explain you something and give you some advises. It is quite known in cardiology that alcohol consumption can cause rhythm problems.We even have a sindrom now,the mondey morning syndrome,related to rhythm disturbance or what we call atrial fibrilation that happens after saterdays whith excessive alcohol consumption. It is not usual that a little glass of wine once a wile can cause you rhythm problems.But it might be that you are a sensitive category.This means that even a little alcohol rises your heart beats,it might give you a simple sinus tachycardia.This mean that your heart beats over 100 beat for minute.Its normal range should be between 60-100beat for minute.It gives you this fast heart beat sensation.Only if you feel that your heart is beating in a caotic way it is another rhythm problem,it might be a paroxysmal atrial fibrilation. If you feel this,it is advisable to take an electrocardiogram in that exact moment. So, as a cardiologyst I can say that you are allowed to drink a glass of wine once a while if you suport it and if you enjoy it.it doesn t cause anything bad.But only if you feel caotic beatings than you need to seek medical atention and you have to avoid alcohol consumption. Hope I was helpful.Wish you good health.Best regards
