Sounds like you had:
123,384 heart beats, or an average rate of 85 beats per minute. If you look at the representation of a heart beat on a monitor, there are different phases, among others, I'm sure, are the P, QRS, and T phases.
Ectopics are premature beats, such as Premature Ventricular Contractions (PVCs), which originate on the Ventricles (lower part of the heart), of which you had 231 (of over 123,000 beats), and 123 Supra-Ventricular Tachycardia beats (of over 123,000 beats). Supra means above, Supra Ventricular means above the ventricles.
Your minimum heart rate was 50 beats per minute, maximum 140, and average 89, close to my original calculation.
Not sure if the rate above 120 is the length of time it was above or the time.
You had no pauses.
Ventricular beats included:
Isolated events are single PVCs, of which you had 171 out of 231.
Bigeminal (the heart beats normally, then PVC, then normal, then PVC, etc) some people get these for hours, you appear to have had 3 bigeminal beats, very brief.
27 couplets (two PVCs together)
And a short run of three beats. Similar to the couplet, just one more.
3 Isolated, 3 Couplets, and some SupraVentricular Tachycardia runs of 100 beats (people have been in SVT for hours or longer).
Please consult your doctor for diagnosis issues. What did he/she say about your results? Hope this helps.
