Hi is your hypertension in control? How often do you get your BP checked? I feel that there are better drugs for hypertension available now than beta blockers which were rampantly prescribed earlier. You can talk to your doctor about other options especially since you have a heart condition. That being said if you are comfortable with beta blockers and your BP is in good control there may not be a need to change your medications. Also it's important to be consistent with your medicines. If you forget to take your tablet take it as soon as you remember. You donot have to wait till evening. Make sure you take one tablet everyday and preferably at the same time. If you do it regularly it will become a habit. I hope this helps. I wish you good health. Take care :)
