I take 25 mg. tablet of Atenolol in 1/4's or 1/2's, check my blood pressure and heart rate and delay the dose if necessary. Sometimes I only take it twice a day. This has worked for me for some time. It sounds like anxiety may be factoring into this, or perhaps this only happens when you are most active. I take Xanax for irregular beats and it helps decrease adrenaline. Hope this is of some help -- good luck to you.
Can betas be taken as and when required ???? Or v have to regularly take the course??
I think that a low dose of beta blockers would do wonders for you. Although your heart rate doesn't seem exceptionally high, having the heart beat in the 130s for an extended period of time could be harmful in the long run. If you are able to take medication to keep your heart rate in a healthier range, why wouldn't you do it?
Sorry you are not getting any inputs, your situation is rather complicated and seems to involve many things other than heart rhythm.
You say 42 Kgs (about 92 pounds, that is very light by USA standards, be we have a problem with people being overweight here), suggests to me low dose medication would be used if at all. The low BP also suggest low dose, but I can say my experience with beta blockers is my blood pressure seems to adjust to taking them. I take BB to lower my HR, just as you need. While my BP was never unusually low, higher dose BB (I have taken as much as 200 mg a day of Metoprolol) did cause problems with forcing my BP too low. I am now on 50 mg (I weigh about 240 pounds, over twice your weight) BB and my BP is in the normal range, still the BB seems to be helping control my otherwise too high a HR.
Some of your symptoms can be caused by medications, and if the side effects are worse than the original symptoms, it seems wise not to take those medications.
I don't see anything alarming about your HR numbers. Still it is generally recommended that one keeps their resting HR below 100, and don't let the active HR get too high. For all but those in their senior years (over 65) a active HR as high as 135 or a bit higher should not cause problems.
I don't know how one raises their BP, I suppose a diet that includes high levels of salt would .... this is not a recommendations, but perhaps you can get a recommendation from your doctor on how to raise you BP.
4) forgot to ask that will it weaken my heart in future????
