another arrhythmia question
by LynnSB, Jul 03, 2002 12:00AM
Thank you for answering my previous question.I saw my cardiologist less than 2 months ago;again, he assured me I don't have life threatening arrhytmias -runs of pvcs,pacs,some brief supraventricular tach & inappropriate sinus tach noted on several ekgs,a stress test(last 8 yrs ago),holters and event monitor(last for 2 weeks in dec.).However,I keep having this near fainting/dizzy feeling. Keep hoping it's related to recent ear/tooth problem not heart. but I have these weak feelings associated with palps and, sometimes, not. Example:this a.m. in car at traffic light, looked left..felt heart beat not quickly but irregular beats..felt weak.. this continued only for seconds but long enough for me to think where i could move the car, get my cell phone and have it ready to call 911. by the time i got my phone opened, palps and most of weak feeling gone.IS THIS SOMETHING you hear from people who just have aggravating, nondangerous palps? at a meeting Mon., sitting for an hr, didn't notice palps at all but suddenly felt weak, dizzy (no graying out or anything). I'm so totallyconfused and scared.I always am told my heart is fine. I don't want to ignore something bad,though yet know my doc has reassured me ad infinitum. Is it unlikely some bad arrrhythmia would develop suddenly?And could having postural orthostatic hypotension contribute to above symptoms -even when seated? And why do i get more palps with bending, turning head, often after eating? Is this vagally mediated? Is that a bad sign?

LynnSB,
Sorry to read of your frightening symptoms. I frequently see young, healthy-appearing individuals with symptoms such as you are describing: weakness, dizziness, palpitations, irregular beats, faintness. The bad news for them is that the symptoms often persist. The good news is that they don't die from them. Attempting to determine the cause of these symptoms can be very frustrating for both physician and patient. In many cases, the best we can do is to exclude life-threatening causes.
Some of my patients describe relief from their fears of dying or debilitation with consultation alone. Other patients require more testing for reassurance. You have already begun somewhat extensive testing with the stress test, holter monitor, and event monitor.
If you experienced your symptoms with the event monitor, and you were able to hit the record function, then you should have reassurance that your symptoms were not from an arrhythmia. If you did not have symptoms while wearing the event monitor, you might consider a longer-term recorder, such as the Reveal recorder (details at www.medtronic.com/reveal/revealplus.html).
The other issue you raise in addition to the palpitations is the possibility of autonomic dysfunction -- lowering of blood pressure after standing, sitting, or eating. The presence of autonomic dysfunction can frequently be detected by a tilt table test. Most large medical centers will have a syncope (passing out) clinic or someone who specializes in syncope.
I've included some references regarding autonomic dysfunction below if you are interested.
Hope that helps.

For years I have had the same problem as you describe of weak spells after experiencing a PAC or PVC. What I believe happens with me is that I have a mimi panic attack in response to an adrenaline surge that I produce myself because I am so fearful of the extrasystoles and what they might portend. As I have come to understand the nature of benign extrasystoles I have become much less fearful of them and as a result I rarely experience the weak spells associated with them. Also as I have come to accept them and not be fearful of them they occur less and less as my nervous system calms down. I think that when one becomes fearful of benign PVCs and PACs over time a general anxiety disorder ensues, specifically obsessive compulsive disorder with overtones of hypochondriasis. A vicious cycle begins and it then becomes increasingly difficult to get rid of the benign extrasystoles as they become a kind of conditioned reflex, initiated originally by fear, that has become habitiuated. Eventually the symptom doesn't need a trigger anymore but occurs on its own. The conditioned reflex is difficult to stop but I think it can be done over time with some mental effort. Many things may help to break this symptom habit including psychoanalysis, medication, hypnosis, cognitive behavioral therapy and biofeedback among others.
Thanks,

I'm not on any meds. I go through periods where the palps are horrible, like today.. i can go for days where i hardly notice any. I feel awful. I don't know what to do any more. this is not panic.. this is real worry about something that comes out of the blue. and yes, i've caught symptoms on a monitor but i have all sorts of palps and feelings.. and it is always in the back of my mind that I DIDnT catch some major bad arrhythmia. i'm so scared
thanks
I too have skipped heartbeat from 15 to 20 times a day, some with lightheadness. I take a topol xl but in small dose, the larger dose make my heart beat too slow and I feeling like I am not there, breathing is too shallow. The beta blocker is suppose to lessing your skipped heartbeat but I still feel them the same. My family doctor has done ECK, hoitor, stress test and they are tested benign. He told me I have extra beat, and to take this medicine if situtation becomes worst then we will seek other opinion. This does not make me feel any better because I am deaf and have to use a special phone to call 911 for help. Needless to say, I can't use a cell phone for tyy equipment I have and I live alone with 9 year old child. It scary at time. I try to relax and not worry so much about it. So doctor tell us is it normal to have up to 15 wo 20 skipped heartbeat within 24 hrs?
You asked me what medications I have tried to help with (PVC/PAC) attacks. Well, I have tried Toprol XL which is a long-acting cardiospecific beta blocker. For me, Toprol XL made be feel puffy, that is, my breathing seemed funny like I couldn't get a deep enough breath. I also felt dragged out on Toprol XL. Perhaps I should have reduced the dosage but I just stopped it. I have also tried Tenormin (Atenolol) which is also a cardiospecific beta blocker. It was OK but my preference is the general beta blocker Propranolol (Inderal). I started out taking it 4 times a day for a total daily dose of 40 mg. I also took Xanax at the same time and Prozac.
