ICD Placement: Before Your Procedure

An Implantable Cardioverter-Defibrillator (ICD) is a battery-powered device that acts as a lifeguard for your heart.

How it Works

The device constantly monitors your heart rhythm. If it detects a life-threatening change, it takes action in two steps:

  1. Pacing: It sends painless electrical pulses to try to correct the rhythm before a shock is needed.
  2. Shocking:If pacing does not stop the abnormal rhythm, the ICD delivers an electric shock to restore a normal heartbeat.
     ICD shocks are typically sudden and uncomfortable. Patients often describe them as a strong jolt or “kick in the chest.” Although the sensation can be startling, the shock lasts only a moment and is delivered to protect your life. 

The Procedure

Duration: 1 to 2 hours | Stay: Usually overnight.

  • Incision: Made just below the collarbone or on the side of the chest.
  • Lead Placement: Wires (leads) are threaded through a blood vessel into the heart OR placed under the skin (depending on the device type).
  • Comfort: You will receive medicine to relax you (sedation) and the area will be numbed.

Managing Anxiety

It is common to feel worried about having an ICD. To help ease your mind:

  • Make a plan for what to do if the ICD shocks you.
  • Focus on how the device will protect you.
  • Talk to your doctor about relaxation techniques.
