Handling the lead without Connector Tool. For leads that require the use of a Connector Tool, use
caution handling the lead terminal when the Connector Tool is not present on the lead. Do not directly
contact the lead terminal with any surgical instruments or electrical connections such as PSA (alligator)
clips, ECG connections, forceps, hemostats, and clamps. This could damage the lead terminal, possibly
compromising the sealing integrity and result in loss of therapy or inappropriate therapy, such as a
short within the header.
Handling the terminal while tunneling. Do not contact any other portion of the DF4–LLHH or
DF4–LLHO lead terminal, other than the terminal pin, even w hen the lead cap is in place.
Programming and Device Operations
Atrial tracking modes. Do not use atrial tracking modes in patients with chronic refractory atrial
tachyarrhythmias. Tracking of atrial arrhythmias could result in ventricular tachyarrhythmias.
Post-Implant
Protected environments. Advise patients to seek m edical guidance before entering environments that
could adversely affect the operation of the active implantable medical device, including areas protected
by a warning notice that prevents entry by patients who have a pulse generator.
Magnetic Resonance Imaging (MRI) exposure. Do not expose a patient to MRI scanning. Strong
magnetic elds may damage the pulse generator and/or lead system, possibly resulting in injury to
or death of the patient.
•Diathermy.Do not subject a patient with an implanted pulse generator and/or lead to diathermy since
diathermy may cause brillation, burning of the myocardium, and irreversible damage to the pulse
generator because of induced currents.
Ensure PTM is enabled. If desired, ensure that Patient Triggered Monitor is enabled prior to sending
the patient home by conrming the Magnet Response is programmed to Store EGM. If the feature is
inadvertently left in the Inhibit Therapy setting, the patient could potentially disable tachyarrhythmia
detection and therapy.
