That is the number of heartbeats recorded in the monitoring period
123 Ventricular beats (1%)
12822 Supraventricular beats (12%)
The next two speak for themselves. 13% total I would think is a rather high percentage.
51 Minimum at 10:42
116 Maximum at 22:38
Needs no explanation.
1624 Beats in Tachycardia >=100 bpm 1% Total
This could be caused by any number of things from walking up steps, and other activity.
3876 Beats in bracdycardia ,=60 bpm 3% Total

This could have been while you were asleep
VENTRICULARS V F R I
0 Bigeminal Cycles
1 Runs totaling 3 Beats
3 Beats longest run 214 bpm 13:31
3 Beats fastest run 214 bpm 13:31
This are VTachs. You appear to have had 3 consecutive beats in a row. Interesting to note it was very close in time to the incident above.
SUPRAVENTRICULARS S J A
132 Bigeminal cycles
4 Runs totaling 12 beats
3 Beats longest run 122 bpm 15:51
3 Beats fastest run 122 bpm 15:51
These are SVT's, You had a bunch of isolated "one offs", plus a large number of couplets. You had four distinct episodes that totaled 12 beats. I don't believe this is too bad, all things considered.
The term "runs" are consecutive beats. For instance, since my cardiac ablation, I occasionally experience 8 to 12 beat "runs" of SVT before it drops out and back to NSR.
Of course, I have no idea what all this means for your health.
How long did you wear the monitor for?
