12.3.1 Marker View
In Marker view, the Marker events are displayed as follows:
• Sensed events, below the baseline, are represented by colored line markers
which use the following color conventions:
o Magenta: Atrial sensed event
o Green: Ventricular sensed event
o Black: Local Sense event
These color references are displayed in the ECG window of the OMNI Smart
Programmer Software screen.
• CCM signal delivery is represented by a marker in the shape of a blue
rectangle above the baseline whose length represents the duration of the
CCM signal.
In addition, labels are shown indicating when the following conditions occur:
• PVC: two successive ventricular sensed events without an intervening
atrial sensed event
• AT: atrial rate above the atrial tachycardia rate limit
• VT: ventricular rate above the ventricular tachycardia rate limit
• A Noise: noise detected on the atrial sense channel
• V Noise: noise detected on the ventricular sense channel
• Long AV: sensed AV interval exceeds “Long AV” limit
• Short AV: sensed AV interval shorter than “Short AV” limit
Warning: The displayed ECG should not be used for clinical decision making. Medical
decisions should only be based on an independent ECG measurement device.
• CCM signal delivery state is indicated by labels as well as by the
background color of the ECG window as follows:
o Inactive: this label appears at the top left of the ECG window as long
as the CCM delivery is not Active. The background color of the ECG
window is white in this case.
o Active-On: this label appears at the top left of the ECG window as
long as the CCM delivery is Active and On. The background color of
the ECG window is green in this case.
o Active-Off: this label appears at the top left of the ECG window as
long as CCM delivery is Active but Off. The background color of the
ECG window is gray in this case.
