As one that has been diagnosed with both PVC's and WPW (at different times by different Physicians), this all appears to be a "which came first - the chicken or the egg?"... I've had a cardiac ablassion, but yet the WPW has returned. I've been told not to worry too much about it, but anyone that has had WPW "episodes" knows that these can mimic heart attacks.. So it's a double edged sword.
I've been told everything from "it isn't serious unless it causes you problems", to "there's no cure for it"... falling off a cliff isn't a problem until you reach the bottom....
It would be nice to get a clear understanding of each, and how they may or may not be related, and if there's anything that could be done to correct it.
I don't have any answers, but I certainly have the same concerns...
Hi was wondering if ever got answers to the short PR and what caused it you don't have WPW. Any information would be appreciated.
I find that an interesting comment. I hesitate to disagree with doctors but from my understanding and my eps explanation ectopic beats like pvcs are not an indication that one has an svt. They may have been caused by and svt but others without an svt like wpw get ectopic beats so it is odd they would come to that conclusion though there may be some new medical research going on that I am not privy to. What I will say is ectopic beats can very well trigger an svt event as Tom said and the two conditions can feed off each other but one can have one without the other. The best way to decipher if you have an svt is to get it caught on a heart monitor however you would likely have noticed or had episodes of sudden rapid heart beat. It generally starts and stops in one beat. If you haven't noticed any of that and they doctors do not see the tell tale sign of wpw on your ekg I suspect it is more likely you don't have it though also as Tom said that doesn't mean you couldn't have another form of accessory pathway svt. But I do truly think you likely do not have svt or you would probably have had more clues.
As for causes of pvcs there are a number of really big triggers like acid reflux and stress so do your best to try and manage any of those issues as well try to stay away from carbs and caffeine/energy drinks. These will irritate the heart causing it to act up. In any event, try to not fret too much about the pvcs. Fretting will make them worse and in general they are harmless in a healthy heart. Take care and hope you continue to improve.
It is thought that PVCs are linked to various forms of SVT (AVNRT and AVRT of which WPW is in) by the fact that they may precipitate an SVT event. My electrophysiologist reported that my SVT was initiated by a single PVC occurring at precisely the right moment in the cycle of a beat. I personally never heard of it the other way around; SVT as a cause of PVC's.
Wolff-Parkinson-White is a particular form of AVRT (what I had) that has a distinct form of conduction. It is the rare direction of conduction that leads to a dangerous form of WPW. Many patients may have WPW, and never even know it.
For some reason, the term Wolff-Parkinson-White is often used by people who are experiencing some form of SVT just as Band-Aid is often used for an adhesive bandage. As you mentioned, WPW more often than not has a tell-tale delta wave on an EGK wave form. Now my cardiologist and electrop[hysiologist swore up and down that they could see a delta wave or "slur" in my EKG, but once they mapped my heart, it turned out to a be another form of accessory path (aka, AVRT) SVT known as Circus Motion Tachycardia. So the presence or not of a delta wave doesn't always indicate WPW, and there are a number of other sudden onset of rapid heartbeat beside Wolff-Parkinson-White.
