Implantable Cardioverter Defibrillator (ICD)
An implantable cardioverter defibrillator (ICD) can be a treatment for eligible congestive heart failure patients who experience arrhythmia.
An ICD is a small device that is surgically implanted in the chest of congestive heart failure patients. The battery-operated device closely monitors the heart for any disruptions in heart rhythm.
It works to shock the heart should it start to beat too slowly or too fast. An ICD resynchronizes an irregular heartbeat to normal or can work to restart the heart should it stop beating.
Today, most ICD technology also includes a pacemaker which triggers the left and right ventricles of the heart to work together properly to pump more blood through the heart and to the rest of the body.
An ICD can help reduce arrhythmia symptoms sometimes suffered by heart failure patients. It can also help improve a patient's blood pressure since it helps maintain proper heart rhythm and blood flow. It can also prevent cardiac arrest and death should a patient's heart stop beating suddenly due to a dangerous arrhythmia.
