Single palpitation followed by sinking feeling then rapid heartrate.

[Magellan407]

Hi,

A couple nights ago, another scary thing happened with my heart. I was sitting down, not anxious or anything, when I had a single, sudden palpitation, followed by a sinking feeling for 3-4 seconds (I could not feel a heartbeat during this time) followed by a sudden, extremely fast heartrate (must have been 180 bpm.) I had shortness of breath during this. This heart rate lasted for probably 5 minutes and then over the course of an hour or so came back to normal. I had fleeting, short stabbing pain behind my heart every now and then, but it did not really bother me.

Of course, I went to the hospital the moment this happened. They didn't really say anything useful, but I noticed on my online results the following day, my EKG said this:

"Normal sinus rhythm
Normal ECG
When compared with ECG of xx-xxx-2015,
T wave inversion now evident in Anterior leads"

(I blanked out personal information)

What is the significant of a T wave inversion in the anterior leads? Also, I was wearing a holter monitor while all of this occurred, so THANKFULLY, whatever happened will show have shown up and I can get a clear answer as to what happened when that comes back. Until then, I am wondering if anyone has any expertise as to what might have happened?

Thanks everyone.

Not sure about the t wave inversion but it sounds a lot like some sort of svt is present with the sudden rapid pulse after an ectopic beat.  Great that you caught it on the monitor.  Let us know the results after you get them.

Interesting. Well, all I can say is praise the heavens that I caught this on the holter. I've had events like this before but nowhere near this magnitude. I was afraid I'd wear the holter and it'd just show my normal pvc's here and there. They'd see that and just turn me away for sure.

It COULD be a number of things.  Your physician would be a much better person to ask instead of me who will most likely scare you with what I know about inverted T wave.

First, it could be normal and there's not a thing wrong with you.  Now, a T wave is normally points upward.  Your is apparently pointing down or inverted. Now it could be nothing, or perhaps some degree of seriousness.  It could be Pericarditis or Myocarditis.  It could be something more serious, a form or ventricular cardiomyopathy called AVRC,a form of adult heart disease.  It could also indicate mitral valve prolapse.

Look, if the Holter caught it, your cardiologist will be able to make the call much better than I.  I hope it works out for you!
