5.3.6. Therapies Brady Therapies

The 24 Hour Heart Rate Curve
The trend of the ventricular heart rate detected in the 24 hours preceding the transmission shows the paced rhythm in blue and the spontaneous rhythm in green
Cardiac Cycles
In DDD, DDD-R, DDD/DDIR, SafeR and SafeR-R modes, the distribution graph provides information about:
  • atrial ventricular association during paced and sensed rhythm
  • information about cycles during atrial arrhythmia and PVCs
  • The percentage of rate responsive paced cycle is displayed in red
  • First 4 bars show the percentage of Ap-Vp, Ap-Vs, As-Vp and As-Vs cycles with respect to the total number of cardiac cycles
  • Last 4 bars show the percentage of PAC-Vs, Vp, Vs events during Atrial Arrhythmia and the percentage of PVC, computed with respect to the total number of cardiac cycles
In VVI and VVIR, the distribution graph displays Vp, Vs, Vs acc.
In DDI and DDIR, the distribution graph displays Ap-Vp, Ap-Vs, As-Vs, Vp, Vs, Vs acc. SafeR

This section presents:

  • The percentage of time spent in AAI
  • The number of switches from AAI to DDD on 3rd degree AV block
  • The number of switches from AAI to DDD on 2nd degree AV block
  • The number of switches from AAI to DDD on 1st degree AV block Arrhythmia History

Provides a list of arrhythmic episodes that have been automatically detected and recorded by the device since the last transmission.

The list displays:

  • Only recorded episodes, not all detected
    • The total number of episodes recorded by the device cannot be higher than 16, including ventricular and atrial ones
    • If more than 16, the device automatically prioritizes ventricular when selecting the ones to be kept
    • Listed in chronological order descending from the most recent episode
  • Each row corresponds to a different episode recorded
    • Multiple episodes detected in the same day are grouped by a grey background color. Episode date is not repeated if more episodes happen in the same day.

The total number of ventricular events detected is provided in the Tachy Therapies and Episodes section.

For each episode the following information is provided:

  • Type of rhythm detected
  • Duration
  • Date
  • Time
  • A separate EGM Report provides the episodes recorded by the implantable device since the last transmission to analyze the corresponding EGM and tachogram

If the list is empty, a message shall be displayed to indicate that there is no new detected episode since the last follow-up

5.3.7. Alert Parameters

Shows the list of all alert conditions that can trigger alert transmissions according to their alert activation status the programmed values for programmable parameters.
  • Alert conditions can be turned ON or OFF in order to trigger Alert transmissions
  • Parameters are set in the programmer during a clinic follow up
  • Regardless of the ON/OFF setting, detected alerts will be displayed in the Warnings section of the report.

5.3.8. Leads Implanted

Provides the list of implanted leads as they are entered on the programmer's patient screen.

The following information is captured for each lead:

  • Manufacturer
  • Model
  • Serial Number
  • Implant on: date
