High diastolic low systolic,
by mslina001, Aug 13, 2006 12:00AM
I'm 25 years old and am having trouble sleeping, loosing weight, have a normal resting hr at 120 and a (with out medication) BP of 120/108, when dr's ran blood work it came back normal except for my TSh which was 10 pnts below the range. (which i guess makes me hypothyroid) The doctors dont have a clue about whats goin on and I'm now being sent to an endocrinologist, and a cardiologist, but the appts arent for a few weeks. Recently they did the 24 hour halter monitor and found that every hour with the 12.5mg(bid) Toprol I take, I'm still having palpitations, and tachycardia....and strange BP's all ranging within 20 pts from the systolic and the diastolic... the Systolic btw is NEVER above 120.... And with the toprol, my bp drops to 100/84, however still have the rapid heart rate. The dr's wont raise the medication to control the heart rate bc my bp would drop too low. Just really confused.... What could it possibly be??

Hello,
I am sorry to hear about your health concerns. They do sound a bit confusing -- I don't recall having a patient with a such a narrow range between systolic and diastolic blood pressure. My first instinct is to not trust the blood pressure reading or think that it inaccurate because of your heart rate.
I agree that seeing a endocrinologist and cardiologist will probably help. They need to rule out organic causes for the tachycardia -- hypothyroidism usually causes bradycardia not tachycardia.
You just need another set of eyes looking at the data to figure out what is going on. To be honest, I am not sure what to speculate is going on. To me the data does not makes sense and more information is needed. That is about the best I can do for now -- sorry.
I hope this helps a little. Thanks for posting.

IST is a hypersensitivity of the heart to adrenaline. This is a problem with the electrical system of the heart, not heart disease or a structural problem, so IST doesn't show as an abnormality in routine tests. Before a diagnosis of IST is made, other causes of rapid heart rate must be ruled out...like thyroid problems.
Symptoms of IST can include fast resting rate, fatigue, poor sleep quality, sweating with minimal exertion and an overreaction to stress due to increase in adrenaline.
IST is often misdiagnosed by GP’s and even Cardiologists. Because this is a problem with the electrical system of the heart, an Electrophysiologist is your best bet for an accurate diagnosis and treatment. If medication, beta blocker or calcium channel blocker, does not control heart rate a cardiac ablation is often necessary. University medical centers are great for dealing with EP issues.
I was really sick for years and nothing showed on the multitude of tests...except my resting heart rate was always above 100. No Dr paid much attention to my rapid rate, even when resting rate was in the 140's. Don’t let your Dr ignore your heart rate because IST accounted for all my symptoms!
I'm currently on 200 mg of Toprol to reduce my heart rate and sometimes it still races.
Good luck on your search for an answer!
