I also spoke to my mother last night about my recent episode and she explained in detail how she has suffered with them. She explained what they felt like to her and they seem exactly the same! She said hers was stress related.
I was over the moon to hear this is in the family, and someone could actually relate to how I feel.
Her response was "I lie on my stomach when they happen, it makes them feel less noticeable". Funny, because that's what I do ... although it doesn't always work.
Exercise and getting up and moving about stops them for me.
It's interesting that everyone has irregular beats--but most people simply don't feel them. We sensitive types do.
Perhaps you've read what actually happens during an ectopic beat? If not, here's a simplified rundown:
The 'Pacemaker' in the upper right atrium normally sets the heart rate, but it's important to know that every cardiac cell in the heart is naturally rhythmic and contractile. They all sort of agree to abide by the timing of the pacemaker, but every now and then, there's an independent or rebel heart cell, or a cluster of rebels somewhere. If you have been diagnosed with PVCs, your rebels are in one of your ventricles.
When you have a PVC, the rebel cells cause the ventricle to contract earlier than usual. Because of the way the heart fills, this means the ventricle has not had the opportunity to get as full as usual, and as a result, this particular contraction is weak, as in *really tiny.* People don't usually feel it at all.
However, there are rules about the next scheduled beat in a normal heart: It cannot contract until certain electrical things happen (called repolarization), so there's a delay. That's the pause you feel. Since the chambers of the heart are elastic, this delay gives the ventricle a chance to fill a bit fuller than normal. Now, the 'Law of the heart' is that it is obliged to try to pump out all the blood that enters it with each cycle, and to do that, the slightly fuller ventricle has to give a big push on this contraction. *THAT* big (but healthy) contaction is the big thump you (we) feel.
When you are at rest, the Pacemaker slows down the heartbeat, and if you have what I've been calling 'rebel' cells somewhere, that's the perfect opportunity for them to do a little firing on their own, which is why you get more PVCs at rest. When you're active, the Pacemaker speeds things up, giving the rebels less opportunity to act up. Jumping rope or doing pushups gets rid of your ectopics--until your heart slows down again at rest.
For some reason, PVC sufferers have a particularly irritable bunch of little cells in the ventricle. No one really knows why this happens, although there are bunches of theories. Anxiety per se is *not* the cause of these beats--but the flood of adrenaline that comes with hyperawareness and fear certainly CAN make them worse.
Still, if your heart has been checked out thoroughly, and if you can perform all your normal activities, then the biggest problem is dealing with the emotions associated with hyper-awareness of your erratic heartbeats. In my experience, the best way to go at this is with the help of a therapist, plus the anti-anxiety medication that is found to be right for you--and it is not a one-size-fits-all situation. Often, it requires a month-long trial of three or four to find the best one.
I agree with you in that I don't buy that anxiety argument either. To me anxiety by definition is caused by an external event that results in a "fight or flight" response due to Adrenaline increase in your system. But what if you have a "chronic" oversupply of Adrenaline that has nothing to do with such an event - at least that's what I think is taking place in my case and I have some proof of that. However, stating it that way doesn't help either you or me.
