I know you say your stress level is low, but, I feel that you still have anxiety due to worrying over those horrid PVC's. I have them, and they scare me, even just a few. The fact that you are worried about them can bring them on.
I would see your cardiologist again, and if he does not seem interested, see another one. Some are so used to the PVC's in patients, they just are not concerned, they don't mean to be that way, but, for them, it is an everyday occurrence.
I did not know about the hyperventilation myself, that is good to know.
Oh yes, have you had an echocardiogram and worn an even monitor, these can help determine what is going on too.
Good luck and please keep us posted as to how you are doing. We are here for you.
I have come across research that impicates hyperventilation or chronic hyperventilation as a possible cause for PVS-palpipations. The theory postulated is that Co2 levels in the body affect oxygen dissipation in the tissues including the heart. Please goole and read up on the work of Dr. Buteyko. Dr. Buteyko was associated with the Russian space program and conducted extensive research on the mechanics of respiration and the altered biochemical states due the imbalance of Co2 / O2 ratios. His team's basic premise is that some form of hyperventilation is the causative factor fora multitute of health conditions.
Sorry to hear that you are going through such a rough patch. I know how bad they suck, and the way you feel is something we all can relate to here. Mine come and go, and at my worst time I had them straight for about 6 months. I felt every single one.
It sounds like you have had all the tests such as stress,echo, bloodwork etc? Is that correct? If not, I would encourage that immediately.
Your symptoms are very similar to mine, and sometimes it is a true struggle for me to remain focused, calm and not to panic. They dont scare me much anymore, but they feel so terrible when they happen. Physically, I can get exhausted when I have a bad patch of them. I do find that Lorazapam tends to help me get through the really bad days, but I am very careful about not becoming to accustomed to that.
I do find that I HAVE to stay busy when I have these episodes. If I just sit still, they are much worse for me.As hard as it sounds, you have to keep living life. That means attending Pharmacy School! Don't let these things run/ruin your life...I can say that because they have done that to me before.It is a daily struggle to stay positive.
I hope that you feel better soon. Consider making another appointment with a cardiologist and try and get some resolution/treatment options that might make you more comfortable.
