Rapid pulse

For the past few years I get episodes of rapid pulse and it's getting worse.  Resting it's usually ok, between 66-85   but when I do simple things like go up stairs or getting dressed it jumps up in the 100's.  I go out shopping and i get out of breath and i can feel my pulse start racing. When I get home I check and it's between 110-95, so I need to sit for an hour to get it back down in the 80's but often it just goes into the 90's.  

When I just roll over in bed I can feel my heart racing and sometimes I wake up with a pulse 110 and it wil go down in the 70's afterI sit for a few minutes.

What can cause this?   I take lisinopril 10mg / 12.5    I was on benicar with a duretic in the past and blamed my pulse on that, so it can't be my meds.

I had every heart test, stress test, thalium, holter minitor, 3d echo.   What's next? my doctor doesnt seem concerned and even put me in 37.5 phentermine to lose weight.

Unless you have an event during the tests there may not be any evidence of an issue, and sometimes the cause is not known. Getting out of breath with every day actiivities and a faster than normal heart rate can be a serious condition.  It is possible your condtion is not heart related or concomitant with a respiratory issue and/or low oxygen level in the oxygenated blood pumped to heart cells...medically termed hypoxia.  

Other possibilities for  tachycardia can be due to an overactive thyroid, imbalance of electrolytes, adverse reaction to medication. You are being treated for high blood pressure...is your heart size and its pumping ability normal?

Hope this helps, and if you have any further questions or comments you are welcome to respond.  Thanks for the question,  take care,

I had every heart test and they found nothing.  This has been on going for the past 4 years off and on.   I noticed lately I get puffy fingers and one day when it was warmer than normal I went out for mothers day.  I came home and my pulse was racing in the 100's and would not go down, my fingers were puffy and my calves and toes looks puffy.  After 4 hours I chugged some water and it improved,   I was also told I was a little low on magnisuim and was told to cut out diet soda.

But my heart racing is getting old, it doesnt do it at rest, only with activity, even bending over sometimes I feel  my heart beating so hard to where i have rest,

I just want this to stop.

Based on the information you provide, I don't believe a neurological disorder can be ruled out. For spme insight, normally the nerve receptors sense the decrease in blood pressure, and activate the sympathetic nerves (increase heart rate).. The receptors (sensors) act as a pathway to send a message to the central nervous system. When called on the sympathetic nerves act on the sinus node (heart's pacemaker) so the heart can beat faster and also make blood vessels constrict (vasoconstriction) causing hgher blood pressure.  A dysfunction of the central nervious system can cause the symptoms you are experiencing.

Normally there is a hormone acts to slow the heart and decrease the heart's force of contractions when an individual when sleeping and the hormone it is mainly produced by the Vagas Nerve. Tha doesn't appear to be happening with you.

Has your symptoms been associtated with central nervious system by your doctor?

I do have MS, had it for 20 years.  But it's pretty benign with the exception of 3 serious attacks but i recovered from them.  It could be possible that maybe MS is causing this, but never heard of it with anyone else.

Pardon my misspelling of the word nervous in the previous!

MS can effect the central nervous system that connects to the heart. "MS is currently believed to be an immune-mediated disorder mediated by a complex interaction of the individual's genetics and as yet unidentified environmental insults. Damage is believed to be caused by the patient's own immune system. The immune system attacks the nervous system, possibly as a result of exposure to a molecule with a similar structure to one of its own".

Also, could there be a problem with your medication that your doctor has overlooked?

I was on benicar 40, then Azor 40/5 plus a diuretic.  I complained of shortness of breath and sometimes I would get a fast pulse so I would stop my meds. My BP would be stable and then 6 months later it spiked because I wasn't on meds.  I would get 180/110 but my pulse was between 45-70.  So my doctor put me on benicar 40 and I would be out of breath just lifting my arms and brushing my hair or putting on my shoes.

Then I asked to be put in lisinopril.  I was put on 10mg with 12.5 diuretic.  Within 3 hours my BP dropped and life was great, then a few weeks later I would wake up wioth 100 plus pulse every morning and  sweat and be out of breath.  then it would calm down for weeks and then come back again.  I don't know what to do,

Your medication is focussed on lowering your high blood pressure and the high blood pressure can be primary with unknown cause or it can be secondary to an underlying cause that should be treated.  

For some insight on the meds: Angiotensin is produced by the kidneys and have important role in regulating blood volume and systemic vascular resistance (blood pressure). Your medication has been to block angiotensin with your first medication, and the current med is an ACE inhibitor that blocks the angiotensin production. I take lisinopril for high blood pressure control and works well with me for the past 7 years. I am also on a beta blocker to maintain a stable heart rate.

The out of breath issue is a known side effect of an ace inhibitor and taking a diuretic increases the risk of side effects. It is possible your doctor hasn't found the best medication and doseage, and your condition does have treatment complications that may include central nervous system (possibly excess adrenaline)  control of blood pressure and heart rate  from a cardiovascular compensatory perspective. Thanks for your response, take care.
