Implantable Cardioverter-Defibrillator

Implantable Cardioverter Defibrillators (ICDs) work much like permanent pacemakers, but have the ability to treat life threatening heart rhythms, from the ventricles, or bottom chambers of the heart. The rhythms can occur from inherited genetic abnormalities, such as Long QT or Brugada syndrome. If your heart is weak, you also have a higher risk of developing dangerous heart rhythms.

There is an additional ICD that can provide cardiac resynchronization for a weakened heart that has a conduction delay between the ventricles which causes the heart to beat with a rocking motion. If a certain criteria are met, the implanted device can, with medications, strengthen the heart over time.

ICDs placement is also minimally invasive and performed under conscious sedation with local anesthesia. The procedure takes less than an hour to complete. You will be discharged the same day with post-operative instructions. You will also have a prescheduled follow up appoint in our office for a wound check and further information regarding your device, as well as remote monitoring from home.

All IDCs have remote monitoring capabilities. The remote monitor for your home will be provided at implant, or will be ordered for you at your follow up visit. Remote monitoring is an important feature, as we will be able to monitor the battery life, leads and for any arrhythmias that may occur. Remote monitoring of ICDs, like monitoring of a pacemaker is recommended by Medicare and can assist us in better managing your care.

When you have your remote set up at home, or if you have any questions, we have a dedicated electrophysiology line at 602-867-3737.

Our staff will be available during regular business hours, to assist you with questions about your monitor.
