" Min. beats count
“
For a Tachycardia or Bradycardia to be determined, the event must have at least the entered number
of heart beats.
According to the following criteria, Tachycardias with wide and narrow QRS complexes are
determined:
1)
"Tachycardia [bpm] “
If the determined heart frequency is bigger than the registered value, a tachycardia is recognized. One
must be careful that the criteria „Min heartbeat number” is fulfilled.
2)
"Min. beats count
“
A tachycardia is determined according to the criteria if the registered number in heartbeats reaches at
least the entered value.
3)
"Wide complex QRS min.
[ms]“
If the duration of the QRS complexes is bigger than the registered value, a tachycardia with wide QRS
complexes is recognised from the raw data channel.
4)
"Narrow complex QRS max.
[ms]“
If the duration of the QRS complexes is smaller than the registered value, a tachycardia with narrow
QRS complexes is recognised from the raw data channel.
Acceleration/Deceleration
4)
„Arrhythmia Variation [%]“
Is the beat-to-beat variation (distance of two succeeding R-waves) higher than this value, an
arrhythmia will be detected.
1)
„Min. duration [s]“
Minimum duration of a continuous increase or decrease of the heart rate.
2)
„Min. change [1/ min]“
Minimum size of the continuous increase/decrease of the heart rate for classifiying as an
acceleration/deceleration.
3)
„Max. duration [s]“
Maximum duration of a continuous increase or decrease of the heart rate.
6)
Limit tachycardie
In this field the limits for tachycardia at night or day can be choosen.
