Hello, I just have a question about heart-beat interruptions. I have an 80-year old mom who recently began to complain about heart palpitations (skipped beats). We took her to the doctor and mad an ECG as well as an Echo measurement. Then she was advised to take a medicine called Betloc ZOK 50 mg (Metopolol). She has been taking it for almost three weeks now, and although her blood pressure got better (dropped) she still has these interruptions. What should we do?
