Thanks for your question on Health Care Magic.
I can understand your concern.
Yes, there are many things in your husband's case times worry about.
He is taking alcohol. So possibility of alcohol induced heart damage is more.
His blood pressure is high, pulse rate is low, so possibility of
heart block is more.
He is also having purple tongue at night. This might be due to
cyanosis. Cyanosis is due to reduced blood supply to the organ. And it is commonly seen in heart block.
So all these are danger signs in him and these need evaluation by cardiologist.
So
consult cardiologist and get done ecg, 2d echo and Holter monitoring (24 hour continuous monitoring of ecg).
Ask him to quit alcohol as soon as possible.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your husband. Thanks.
