24 hour Holter showing NSVT.

[Samazeuilh2]

I’ve received the result of my 24 hour 12-lead Holter, but not the interpretation-I will not see the consultant for about 7 weeks. The summary reads: “Indication: to quantify VE morphology and burden. Sinus rhythm with occasional supraventricular ectopics. One run of non-sustained ventricular tachycardia (15 beats at 118bpm). Reduced heart rate not specified ventricular or atrial (but mostly ventricular)profile with rare non-conducted SVEs. HR 38-73. Average: 53bpm. 227 polymorphic ventricular ectopics, including a run of non-sustained ventricular tachycardia (15 beats at 118bpm). 2851 Supraventricular ectopics including including five couplets one triplet and salvo.”

Much of this sounds reasonable but I was rather concerned about the tachycardia. After some googling I came across the following “Non-sustained ventricular tachycardia (NSVT). VT can be a potentially dangerous rhythm, especially in the setting of coronary artery disease (I had a bypass 20 months ago). Even though it’s non-sustained, VT indicates that the ventricles are electrically unstable at times. If this becomes sustained, it can lead to hemodynamic compromise or even sudden cardiac arrest. Non-sustained VT often requires further evaluation, especially given your heart disease history.

Does anyone have this condition or know anything about it? Have I got hold of the wrong end of the stick?

You need professional opinion here. VT very much depends on you and your heart. Non-sustained VT is likely more common than anyone knows. You had a very short run. I would guess the cardiologist will pooh-pooh it and say not to worry!

Dr Google is a very bad source of information about VT, I fe. Also, you might have a bundle block, as I have, and that can create an ECG that looks like VT but isn't. Again, your doctor will know.

I do have BBB. You are also right that NSVT is not easy to evaluate. I’ll just have to be patient and wait for the appointment- I hope you are right and it turns out not to be of concern.

I very much doubt that it would have been VT in that case. I went rushing to see my consultant when my ECG showed just this, too. He explained that it was an artefact of the LBBB and was all atrial and not ventricular.

He explained that LBBB prevents the ECG working properly such that only an expert eye can interpret it. The initial results of your ECG will have been done by computer AI which us easily fooled.

You can book next year’s holiday after all!

That’s very reassuring. Many thanks.
