Blood Pressure
BarbHawkins posted:
About 4 years ago I had to have a defibrillator put in my chest which replaced a pacemaker . From the moment it was put in I have had trouble with my blood pressure suddenly dropping, sometimes when I try to do physical work and sometimes for no reason at all. It will drop into the 60/40 range which stops me in my tracks and gives me a terrible headache in the back of my head and a severe backache in my upper back and shoulders. My doctors don't seem to be able to figure out what is wrong and I'm not sure they are putting a lot of effort into it. They tell me my defibrillator is working fine and my ejection fraction is good and that is all the help I get. It is causing major disruptions in the way I live my life because I am spending half my time in a recliner or on the bed. Does anyone suffer from the same symptoms and are there any solutions.

Have you been seeing an electrophysiologist? That is a cardiologist sub-specialty that deals with heart rhythms.

The basics about blood pressure

As reported, the complex human body is usually able to keep blood pressure (BP) within safe/acceptable limits, but sometimes changes in lifestyle, health, side effects from prescription drugs, or changes in metabolism, make this difficult. This can cause the BP to become consistently higher or lower than normal, or just spike up and then drop down.

Compensatory mechanisms that control BP involves changing the diameter of veins and small arteries (arterioles), the amount of blood pumped out from the heart per minute (cardiac output), and the volume of blood in the vessels.

Best of luck down the road of life.

As far as I know I have only seen the regular cardiologist and the Dr.who deals with the defibrillator, who could very well be an electrophysiologist. When I told him what my symptoms were he said quote, "well Mrs. Hawkins we've never heard anything like that so if what you're saying is true, you'd be the first". I went to another device specialist, well known I might add, who checked the defibrillator and couldn't find anything wrong either. To me it seems like the defibrillator is working fine it is just causing other problems in my vessels or something. They left the old wires from my old pacemaker in there because they said it would be took risky to take them out, could that be a problem? Another symptom I have is blood rushing to my head when ever I bend over; tying my shoes, brushing my teeth etc. My face immediately gets red and flushed and I feel like I have someones hand around my neck, restricting the blood flow.

Thanks for your input. It seems to me I might have a blood flow issue, I'm just having trouble getting anyone to address it. What kind of compensatory mechanisms are you talking about that change the diameter of veins and small blood vessels?
billh99 replied to BarbHawkins's response:
That specialist was most like a electrophysiologist.

You said your defib replaced a pacemaker. Those are two different functions. So I assume that you difib is a model that also had pacemaker functions.

My first thought was that the HR might be dropping because of non-working/misadjusted PM function. I don't know what kind of info the unit records. Ask your doctor if it record low HRs?

But after your lastest message I am thinking in a different area. Something that is affecting the system that automatically controls BP.

One cause might be a blocked or pinched vessel. Have your cardioid arteries (ones in the neck) been checked.

There are some syndromes where the automatic nervous system goes out of whack. Here is one, RDS.
