How does an implantable defibrillator work?
The ICD is a vigilant guardian of your heart:
- Implanted under the skin, usually beneath the collarbone
- Connected to the heart by one or more leads
- Continuously monitors your heart rhythm
- Acts automatically in case of a dangerous arrhythmia
When a rhythm disorder is detected, the ICD can act in two ways:
- Rapid pacing: a gentle and painless method used first
- An electrical shock: a stronger intervention, delivered only if necessary
In addition, most modern defibrillators also include a pacemaker function to prevent the heart from slowing down excessively.
