Why do readings for QRS Duration on my ECG flucuate?

Posted by robertt48 @robertt48, Mar 28 1:36am

I am wondering why the QRS Duration levels detected on my last three ECGs fluctuate?
2020: 121
2023: 115
2024: 127

I'm no expert, but there is such a metric as 'heart rate variability'. HRV. Some variability is associated with good heart health. Often, hearts with very little variability in their rate are in a spot of bother.


Unless you have some formal indication of an arrythmia or tachycardia, or even of bradycardia, you appear to be doing just fine. 😀
