Thanks alot Paul

Today i went to see the nurse and she gave me my holter results and everything is fine (yess!)
But just one thing i would like to know since i'm a total newbie at medical terms lol:
I'm not trying to find problems where there isn't so no i don't ask you guys this to try to find if maybe they missed something this ain't the case. I'm just trying to understand the medical language:
Basically on the 'overall' paper there's 3 category:
- Rate Dependent Events
- Ventricular Events
- Supraventricular Events
In rate dependent events it say that my lowest heart rate was 45 (when i was sleeping most likely) and highest 126
In the Ventricular events it say:
431 beats (.45% of all beats) with:
V Tach Runs: 4 (what is that?)
Couplets: 27 (what is that?)
Triplets: 1 (what is that?)
Bigeminy Runs: 1 (what is that?)
In the supraventricular event it say:
173 beats (.17% of all beats) with:
SV Tach Runs: 6 (what is that?)
Couplets: 51 (what is that?)
If anyone have any ideas what that mean (not the results itself but the words) please let me know!
Thanks
