I lost 40 pounds back in 2007.  I was always in great shape but had kids and put on too much weight.

My BP was starting to push borderline high and my doc started talking about treatin, I was only 38!!  no way man.  I was 140/90.

I lost the 40 and my bp went down to 110/65.  I'm not kidding.  amazing what weight can do to your BP.  I lost the weight through diet.  I cut back to 1800 calories per day.  The weight just flew off for me.  I used to body build at a near competitive level.  I didn't even exercise.  I do now, and it's amazing the diff of the 40 pounds made.  I can feel a huge different when I run or bike.

Take is-something_wrong's advise.  

I work in the technology industry in tier 3 level support.  That means when everyone else has shrugged their shoulders in tryiing to fix a bad problem it comes to my team.  We never treat symptoms of a problem.  We go for the root cause.  I think that's what you should do.  I see you discussing the symptoms and trying to treat that.  you're going to need to treat the root causes here, and quickly.

Impossible to say, your EKG must be interpreted by a cardiologist to differ supraventricular tachycardia with wide QRS from ventricular tachycardia. However, you need to understand the following (sorry to seem a bit brutal here..)

Your condition is possibly serious (hypertension >200 mmHg systolic with slight exercise, angina pectoris at age 31, severe overweight and possible ventricular tachycardia). You need to do something. You refuse to get angiography done (which is a simple procedure, it takes 15 minutes and it will reveal which arteries that may be blocked, and most important, they can be treated by inserting a stent, and the angina is gone if you start living healthy..). Also, you need to see a someone specialized in nutrition, because you need a dramatic weight loss. That will likely reduce or maybe normalize your blood pressure.

Look, you're 31!!! Hopefully you have 50 years in front of you, do you want to live them in a nightmare like this?

I strongly advice that you reach the open hand from your doctors and get help. Why are you so afraid of doing that?
