Genetic vs developed

[sonny372]

Hi everyone. I was wondering how people view genetic born arrhythmias vs people who have developed them latter in life. I developed mine in my late 20's. Now I am from the camp that if you develop them then you have had damage done to your heart and that these types are more unstable and unpredictable in the future. I say that because mine have morphed into something else. Also I was wondering if with supraventricular tachy you are suppose to feel hard heavy beating. Because I get fast runs after a skipped beat that are not giving me a pounding sensation which makes me think I am getting something else. What are your thought. Have a great day!

Sorry, mess up a sentence in my previous post. The inability to edit is killing me as my thoughts often go faster than my fingers!

"I never realized it though because the resulting SVT kind of block it out. It was only after I recorded an event on my long term monitor did I it. "

-should be-

I never realized it though because the resulting SVT kind of blocked it out. It was only after I recorded an event on my long term monitor did I observed it. (the initiating PVC)

Not sure how to answer your question.  I can only pysically relate to my condition, WPW.  I was born with this condition, and it manifested itself at 6 years of age. This is believed to be genetic, but I no of no one in my family ie. mother, father, grandparents that had an "active" case of WPW with exception of me.  Interestingly, my cardiologist has told me that despite 54 years of SVTs, there doesn't APPEAR to be any damage to my heart, and a post ablation EKG show a perfectly normal wave form that's remarkable different than my pre-ablation waveform. Gone is the little delta wave or slur in the QRS complex and the shortened PR interval.  This was all good news!

Regarding your question regarding SVT.  SVT can encompass a whole bunch of tachycardias, but I think that when most people say SVT, they're speaking of the kind that has a sudden onset; literally 60 to 200 in one PVC. Yes, my WPW SVT had an agressive, hard feeling to it.  I could hit 200bpm under heavy physical exertion, and it wouldn't feel anything like it did when I was having an SVT episode of 200 bpm.  It's hard to explain, but it felt distinctly different.  The latter hard a hard, agressive beating, and my chest felt like a heavy weight was on it.

My EP told me that a lot of things have to come together perfectly at the right time in order to initiate SVT.  As you observed, they typically begin with a PVC.  I never realized it though because the resulting SVT kind of block it out. It was only after I recorded an event on my long term monitor did I it.  I could vave dozens of PVCs and nothing would come of them.  Then suddenly Bam!, it would take off without warning.  I hope that in explaining my observations, that it will help you in comparing it to yours.

I'm a bit confused by your post, how do you know what you have "morphed" into something else - what did you have and what do you think it morphed into and why?

I've had just about every arrhythmia caught on monitors, except Afib and I'm trying to understand what you're saying.  Genetic ones would be things like WPW?  I'm not sure of others that would be genetic, can you explain more?

I'm really interested in this; I've had arrhythmia's since I was young along with fainting and been told everything was fine normal, nothing was wrong until 2009 at age 42 - my my pvc's seemingly "morphed" into malignant arrhythmia's - which can't be explained - and is very confusing' I haven't read or heard they change - I've read whatever you have is what you have.
