Need help reading remote report
A friend who originally got a pacemaker because of vaso-vagal syncope asked me for help interpreting the following:
Scheduled remote reviewed. Normal device function.
18 new VHR events logged 31 seconds to 12 minutes 25 seconds w/ rates 150's bpm; EGMs suggest SVT
AF burden <1%; longest 1 to 3 hours; V rate histogram shows ~90% binned >110 bpm; available EGM suggest SVT
Next remote 91 days. HB
Q. V rate histogram shows ~90% binned > 110bpm
What is "histogram"?
What is "binned"
Q. How serious is SVT at this frequency of occurance?
Q. What is EMG?
