Hello and thanks for posting the query
Your treating doctor has prescribed a good and effective medication as per the symptoms and procedure you have explained in the query. But as you are facing side effects of medicine like indigestion, tiredness and weakness, we have a lot of options to alter the medication. Now coming to your queries:
1. Beta Blockers: Beta blockers are indicated in Hypertension, angina and Ventricular Tachycardia (in Holter). You have all of them, a good and right choice of medicine. Since you have are presenting with side effects of the medicine, we have other options; calcium channel blockers like verapamil and dilzem. They are equally effective in controlling heart flutter or ventricular tachycardia. If needed another medicine can be add to control Blood pressure. You have to continue the medications till the Ventricular tachycardia episode quits.

2. Imdur: It contains Isosorbide Mononitrate and reduces the occurrence of angina by dilating the blood vessels and finally reduces the blood pressure. Since you have shortness of breath you cannot take a chance of stopping the medications, it can be related to heart unless proved.

Some measures you can take to control your symptoms are:
1. Reduce your weight and maintain it according to your height.
2. Keep your blood sugar level in control. Check your HbA1c every 3 monthly, it should be less than 7.5.
3. Avoid all fatty, oily and sugary food products. Use sugar free products.
4. Take baked food as much as you can.
5. Do regular exercise as much your body allows you. You can do it twice a day.
6. Keep your lipid profile components in control.

You are 52 and young as a cardiac patient, so by reducing the risk factors you can reduce the chances of occurrence of Coronary Artery Disease and need not to again go for the stunting procedure.

In my opinion consult your doctor again and tell about your condition and discuss it. I am sure your doctor will help you and alter your medication as per your need.
Hope I have answered your query. Write again if have other related queries.
Best Wishes and get well soon.
Dr. Kulbir Singh
