The Cardiac Device Clinic provides comprehensive evaluation and management of implanted cardiac devices, including pacemakers and implantable cardioverter-defibrillators (ICDs).

These devices regulate heart rhythm and, in some cases, deliver life-saving therapy for dangerous arrhythmias. Regular device monitoring ensures proper function, battery longevity, rhythm detection accuracy, and appropriate therapy delivery.

Our clinic provides structured in-office interrogation and long-term surveillance of implanted devices.

​

Implanted devices provide continuous rhythm surveillance and therapeutic protection. The Device Clinic integrates device data with consultation findings, imaging results, and rhythm monitoring to guide precise arrhythmia and heart failure management.

Ongoing device follow-up ensures both safety and optimization of long-term cardiovascular outcomes.

​​

Device follow-up is essential for patients with:

  • Permanent pacemakers

  • Implantable cardioverter-defibrillators (ICDs)

  • Cardiac resynchronization therapy devices (CRT-P / CRT-D)

  • Conduction system pacing systems

  • History of significant bradycardia

  • Prior ventricular arrhythmia

  • Heart failure requiring device therapy

Regular follow-up ensures:

  • Proper sensing and pacing thresholds

  • Battery status monitoring

  • Detection of atrial fibrillation or other arrhythmias

  • Confirmation of appropriate device therapy delivery

  • Optimization of programming settings

Device interrogation can identify:

  • Atrial fibrillation burden

  • Ventricular tachycardia or ventricular fibrillation episodes

  • Inappropriate shocks

  • Lead malfunction or impedance changes

  • Pacing dependency

  • Percentage of ventricular pacing

  • Battery longevity and elective replacement timing

  • Heart failure trends (in devices with physiologic monitoring features)

In many cases, devices provide continuous rhythm data that supplements mobile cardiac telemetry and in-office EKG findings.

Device interrogation is performed in-office using a manufacturer-specific programmer.

  • A telemetry wand or wireless communicator is placed over the device

  • Stored rhythm data is downloaded

  • Lead performance and battery status are evaluated

  • Programming adjustments are made if necessary

The visit typically takes 20–40 minutes.

No needles, sedation, or invasive procedures are required.

No special preparation is required.

Patients should:

  • Bring their device identification card

  • Inform the clinic of any recent shocks, symptoms, or hospitalizations

  • Continue medications unless otherwise directed

If remote monitoring is established, ensure your home monitor remains connected.

Device interrogation is non-invasive and safe.

Programming adjustments are performed under controlled conditions and tailored to the patient’s rhythm profile.

No electrical shocks are delivered during routine interrogation.

After the device is evaluated:

  • Findings are reviewed with you

  • Any arrhythmia events are discussed

  • Programming changes are explained

  • Battery longevity estimates are provided

  • Follow-up interval is scheduled

If significant arrhythmias are identified, medication adjustments or electrophysiology referral may be recommended.

For ICD patients, shock history and arrhythmia burden are carefully reviewed.
