The primary nursing concern for a patient with a pacemaker is monitoring device function and preventing complications such as infection, lead dislodgement, or pacemaker syndrome. Nursing interventions include: assessing for proper pacing (checking pulse, ECG); monitoring incision site for signs of infection (redness, swelling, drainage); educating about activity restrictions (avoiding heavy lifting, magnetic fields); and ensuring regular device checks (interrogation). Patients should report symptoms like dizziness, palpitations, or hiccoughs (may indicate lead perforation). Documentation includes pacemaker settings, patient symptoms, and education provided. Nurses also coordinate with cardiology for follow-up. Pacemaker batteries typically last 5-15 years and require replacement. Awareness of electromagnetic interference (e.g., MRI, security gates) is crucial. Effective management ensures optimal cardiac function and prevents device-related issues.
