ATR exit count. Exercise care when programming the Exit Count to low values. For example, if the
Exit Count was programmed to 2, a few cycles of atrial undersensing could cause termination of mode
switching.
Proper programming without an atrial l e ad. If an atrial lead is not implanted (port is plugged instead),
or an atrial lead is abandoned but remains connected to the header, device programming should be
consistent with the number and type of leads actually in use.
Left ventricular lead conguration. Proper programming of the LV coronary venous Lead Conguration
is essential for proper LV lead function. Program the Lead Conguration in accordance with the number
of electrodes on the LV lead; otherwise, erratic LV sensing, loss of LV pacing, or ineffective LV pacing
might occur.
Left Ventricular Protection Period (LVPP). Use o f a long LVPP reduces the maximum LV pacing
rate and may inhibit CRT at higher pacing rates.
Sensing adjustment. Following any sensing range adjustment or any modication of the sensing lead,
always verify appropriate sensing. Programming Sensitivity to the highest value (lowest sensitivity) may
result in delayed detection or undersensing of cardiac activity. Likewise, programming to the lowest value
(highest sensitivity) may result in oversensing of non-cardiac signals.
Patients hear tones coming from their devices. Patients should be advised to contact their physician
immediately if they hear tones coming from their device.
Patient use of patient triggered monitor. Determine if the patient is capable of activating this feature
prior to being given the magnet and prior to enabling Patient Triggered Monitor. Remind the patient to
avoid strong magnetic elds so the feature is not inadvertently triggered.
Patient initiate stored EGM. Consider having the patient initiate a stored EGM at the time Patient
Triggered Monitor is enabled to assist with patient education and feature validation. Verify the activation
of the feature on the Arrhythmia Logbook screen.
