An implantable cardioverter defibrillator is a battery powered device which is placed under the skin in a surgery to keep track of a patient’s heart rate. Thin wires connect the ICD to the heart, which, if an abnormal heart rhythm is detected, deliver an electric current to restore a chaotically or fast beating heart to a normal rhythm. ICDs are useful in preventing sudden death in patients with known, sustained ventricular tachycardia (a type of arrhythmia) or fibrillation. Studies have shown ICDs to have a role in preventing cardiac arrest in high-risk patients who haven't had, but are at risk for, life-threatening ventricular arrhythmias. They are a common occurrence now, as cardiologists advise patients with risk of arrhythmic problems to have it implanted.

Who Needs An ICD?

As mentioned above, a cardiologist or heart specialist may recommend an ICD if a patient has a life-threatening arrhythmic problem, but also if:

• The patient has had a ventricular arrhythmia
• Has had a heart attack
• Has survived a sudden cardiac arrest
• Has Long QT syndrome
• Has Brugada syndrome
• Has a congenital heart disease or any other condition which can result in sudden cardiac arrest

There are a few precautions one must take after an ICD has been implanted in the body, like being aware of ones surroundings and staying clear of devices that may cause a disruption in ICD’s signalling. Particularly devices with strong magnetic fields.

One can find Top Heart Hospital in Patna, known to have the Best Heart Specialist and Cardiologist in Bihar. Patna has recently become one of the places to have the best cardiology treatment and leading cardiologists in India.
