My husband has had a lung infection for about 3 weeks & being treated with antibiotics. He has suddenly started having an irregular pulse 40 - 60 bpm, normal for him is about 80 bpm. Dr. does not think it is anything to worry about.

I'm wondering if a lung infection or the antibiotics could be the cause of this? We think a blood pressure med he took for a short time caused the lung problems and wonder if it may have damaged something else. Thanks.
