Implantable Cardioverter Defibrillator Leicester
Implantable cardioverter defibrillator (ICD)
An ICD, or implantable cardioverter-defibrillator, is a compact apparatus designed to manage individuals experiencing perilously irregular heart rhythms.
This device administers controlled electrical impulses to stabilise abnormal heart rhythms, particularly those posing significant risks such as triggering a cardiac arrest.
The human heart operates through its intrinsic electrical system, orchestrating each heartbeat. This system generates electrical signals that traverse the heart, prompting its contractions to pump blood effectively. Any disruption in this process can lead to an irregular heart rhythm, known as arrhythmia, necessitating the installation of an ICD.
How does an ICD work?
An ICD is placed under the skin, usually in the space just below the collar bone (clavicle) to monitor your heart rate. Thin wires connect the ICD to the heart, where it's always checking your heart rate and rhythm. It monitors your heart rhythm through the electrodes.
If an ICD notices a dangerous heart rhythm it can deliver one or more of the following treatments:
-
Pacing – a series of low-voltage electrical impulses (paced beats) at a fast rate to try and correct the heart rhythm.
-
Cardioversion – one or more small electric shocks to try and restore the heart to a normal rhythm.
-
Defibrillation – one or more larger electric shocks to try and restore the heart to a normal rhythm.
How is an ICD fitted?
The ICD is surgically implanted just beneath the collarbone, resembling a pacemaker but slightly larger than a matchbox.
Comprising a pulse generator powered by a battery-operated electronic circuit and one or more electrode leads, the ICD is inserted into the heart through a vein.
An alternative variation, known as a subcutaneous (under the skin) ICD or SICD, is suitable for certain individuals. Functioning similarly to a standard ICD, the SICD is placed beneath the skin of the chest, outside the ribcage, without the need for leads into the heart. Your doctor will discuss this option with you if it is deemed appropriate for your situation.
