The medical community has mixed thoughts on the subject. I have read one alcohol drink is beneficial for the heart. Another school of thought advises against.
Heavy drinking is a depressant on the system and of course would be contraindicated as it would enhance the effect of a BB to slow the heart rate, etc. I believe a drink or two is a stimulant? and may just offset some of the BB effect for a short period of time.
I don't drink in public establishments anymore as I don't wish to be exposed to the smoke.
I have the occasional drink. I usually do one of two things 1) if i plann on having several drinks then i will not take my BB that day, 2) limit my drinks to one drink. Alcohol can also speed up your heart rate so becarefull how much you actually drink and what you drink. As you could end up out of rhythm and that would be hard to explain at the ER.
It is really not a good idea to miss a dose of your BB. I have dealt with the arrhythmias for 9 years now and 4 different drugs so I just do as i please mostly. I find if i drink with my BB then one drink really affects me badly, I start with side effects ( hot, headache, lightheaded, shakey) so I know one drink is my limit. But if i am planning to drink like i do once a year (one weekend a year i drink quite haevely) I don't take my BB and i am fine.
I find the alcohol increases my heart rate but it depends what i am drinking.
Alcohol affects people differently and circumstances will affect people differently at other times. There is psychobiological component related to alcohol.
Some people at times become mellow and relaxed and obviously the state one's system is different from times if and when one is agitated, billigerent, obnoxious, etc. after a few drinks. Obviously these people will have elevated HR due to the physicogenic aspect.
That is may thesis based on years of experience and observation.
