i am 20yrs old, 55kgs, height-5"1, rarely drink caffein. father is diabetic, am occasional drinker and smoker. i have benign supraventricular ectopic beats,got an holter test and the report shows 1345 prem. supraventricular complex, 73 supraventicular bygeminy and 38 supraventricular couplet. i have been prescribed prolomet xl 25 for 4 weeks. my query is, is it necessary totake b-blockers for this benign condition? and is occasional drinking bad with this heart condition?
