Figure 26: AES/AT classification
Atrial sense events that occur within the AESW are classified as AES.
The AESW timing is triggered under the following conditions:
— The AESW starts at the end of the AARP until the requirement for
atrial prematurity is met.
— The requirement for atrial prematurity can be programmed
within the range of 5...(5)...50%.
— The atrial prematurity is the percentage of the last four PP
intervals.
An atrial prematurity of 25% means that an atrial sensed event
qualifies as an AES when the PP interval is at least 25% shorter than
the average of the last 4 PP intervals.
Determining Arrhythmia Ranges
The diagnostically relevant arrhythmia ranges are limited by rate
limits.
