Permanent pacemaker — definitive therapy for irreversible block
Right ventricular pacing — standard
Conduction system pacing — emerging preferred option
Avoids pacing-induced cardiomyopathy from RV apical pacing

Patient Discharge Instructions
copy discharge instructions
Diagnosis and basic explanation
Third-degree heart block diagnosis
Complete block of electrical signals between heart chambers
Heart depends on a slow backup rhythm
Treatment depends on whether the cause is reversible
Pacemaker post-implant instructions
Activity restrictions
Avoid raising the arm on the pacemaker side above shoulder level for 4-6 weeks
No heavy lifting > 10 pounds for 4-6 weeks
Driving restriction until cleared by cardiologist — typically 1 week
Wound care
Keep incision dry for 5-7 days
No submersion in water until healed
Wound check appointment in 1-2 weeks
Electromagnetic interference
Avoid strong magnets and MRI unless device is MRI-conditional
Inform medical staff of pacemaker before any procedures
Airport security — inform screeners and carry device ID card
Device follow-up
First device check at 2-12 weeks post-implant
Every 6-12 months thereafter or per remote monitoring schedule
Return to emergency department immediately
Cardiac warning signs
Syncope or loss of consciousness
Near-fainting or severe dizziness
Chest pain or pressure
Palpitations or very slow heart rate
Sudden shortness of breath
Pacemaker warning signs
Hiccups at regular intervals — possible lead perforation
Pacemaker site swelling, redness, or discharge
Feeling pacemaker is not working
Medications and follow-up
Complete prescribed antibiotic course if Lyme carditis
Doxycycline or amoxicillin as prescribed
Full 14-21 day course required
Avoid reinitiation of AV nodal blocking drugs if drug-induced
Discuss medication changes with cardiologist
Cardiology follow-up within 1 week
