High heart rate during exercise

I am 33 and I have had a high HR for years.  In my early 20s I was evaluated by a cardiologist and after many tests we decided against a beta blocker as a possible treatment.  I am now training to run a 1/2 marathon and I too am noticing an extreme jump in heart rate with exercise even though I have been gradual on my training (these are the same symptoms I have had 10 years back).  Within 2 minutes of jogging, my heart rate is in the 180's and has gotten as high as 210, it goes down into the 160's within a minute if I stop and walk.  My normal rate (just doing things about the house or work) is around 90-110 BPM, I don't smoke or drink and I weigh 120lbs.  I have been exercising regularly for 6 weeks now and gradually increasing intensity each week, but no change in HR issues. Is there some sort of exercise program I could follow that would train my heart to beat at a slower rate (i.e. interval training or REALLY long low intensity workouts at desired rate)?  I don't want to hurt myself when I am trying to be healthy!

Are you staying away from caffeine, black licorce?  The 210 is alarming in that once a heart reaches 200 it does not work as it should and simply shakes.  The 90 - 110 while doing housework is not that high.  Mine is usually that when hanging around the house not doing too much or doing a little.  What is your blood pressure numbers?  Sounds like you have some adrenaline issues in which your heart races during exercise.  I have this condition and there is really nothing that can be done except beta blockers which have side effects.  My cardiologist told me to expect this heart racing with exercise and not to ride a bike or run.  Do you get lightheaded or pass out when your heart rate gets too high?  Do you take vitamins and a vitamin B supplement?  There are a lot of people not getting enough vitamin B12. The B vitamins really help to calm and relax.  I am 44 now and I have not been able to run since I was 18.  I have not been able to ride a bike since I was 23 in which I kept passing out when getting off the bike.  My blood pressure runs 90/59 and LDL level is 79, so supposedly my hearts okay as far as I know from all the heart testing I have had in the past.
