Notes:
●
Episodes that occur during a device session are not available to view in the episode
records until an interrogation is performed. The interrogation must be performed after
episode termination.
●
For most episode types, when the log capacity is reached, data from the most recent
episode will overwrite the oldest episode data in the log. For High Rate-NS episodes,
if the log capacity has been reached and an RV Lead Integrity Alert is triggered, no new
episodes will be added to the High Rate-NS log and no existing episodes will be
overwritten until the device is interrogated. This allows the episodes that triggered the
alert to be viewed. Overwriting of the oldest High Rate-NS episode data with new data
resumes after device interrogation.
6.8.3 Viewing episode records
An episode record displays detailed information about the episode currently selected in the
episode log. An episode record is initially displayed in the lower portion of the Data -
Arrhythmia Episodes screen and can be maximized for better viewing. For a particular
episode, you can display the following information:
●
an interval plot
●
a strip chart of the stored EGM (if available)
●
a text summary
●
a QRS display showing Wavelet template match scores (For more information, see
Section 8.4, “Discriminating VT/VF from SVT using Wavelet”, page 326.)
