IMPORTANT NOTICE: At Fortis Healthcare, we are fully supportive of the National priorities set out by the Hon’ble Prime Minister of India. Further to the directives of the Government provided in their press release dated 8th Nov 2016, payments at Government hospitals can be made through 500 and 1000 Rupee denomination notes. In view of the hardship being caused to the large number of patients at private hospitals, we have made an urgent representation to the Government that this exemption should apply equally, for payments, at private hospitals. We are following up with the authorities and hope the Government will step in quickly to resolve this anomaly. Meanwhile, at Fortis hospitals across the country, we continue to accept payments through credit card, debit card and electronic banking transfers. As 500 and 1000 Rupee denomination notes are no longer legal tender we are only accepting 100 Rs and lower currency notes. As per Government regulation, a PAN card and legitimate ID proof is however required for payments in cash exceeding Rs 50,000. Meanwhile we continue to ensure that emergency cases get immediate medical attention without delay whatsoever and have put in more administrative staff and help desks to assist patients.

Implantable cardioverter-defibrillators (ICDs)

An implantable cardioverter-defibrillator (ICD) — a pager-sized device that's implanted into your chest — may reduce your risk of dying if the lower chambers of your heart (ventricles) go into a dangerous rhythm and stop beating effectively (cardiac arrest). You may need an implantable cardioverter-defibrillator if you have a dangerously fast heartbeat (ventricular tachycardia) or a chaotic heartbeat that makes it so your heart can't supply enough blood to the rest of your body (ventricular fibrillation).

Implantable cardioverter-defibrillators work by detecting and stopping abnormal heartbeats (arrhythmias). An implantable cardioverter-defibrillator continuously monitors your heartbeat and delivers extra beats or electrical shocks to restore a normal heart rhythm when necessary. An ICD differs from a pacemaker — another implantable device sometimes used to treat less dangerous heart rhythms, such as those that occur in the upper chambers of your heart (atria).


Why it's done Risks How you prepare What you can expect Results

You may have seen TV shows in which a hospital worker or paramedic "shocks" an unconscious person out of cardiac arrest with a pair of electrified paddles. An implantable cardioverter-defibrillator (ICD) does the same thing, only internally and automatically when it detects that your heartbeat is abnormal.

An ICD is surgically placed under your skin, usually below your left collarbone. One or two flexible, insulated wires (leads) run from the ICD through your veins to the lower chambers of your heart.

Because the ICD constantly monitors for abnormal heart rhythms and instantly attempts to correct them, it helps treat cardiac arrest, even if you're hours away from the nearest hospital.

How an ICD works

When you experience a rapid heartbeat, the wires from your heart to the device transmit signals to the ICD to send electrical pulses to regulate your heartbeat. Depending on the problem with your heartbeat, your ICD could be programmed for these therapies:

  • Low-energy pacing therapy. You may feel either nothing or a painless fluttering in your chest when your ICD responds to mild disruptions in your heartbeat.
  • Cardioversion therapy. A higher energy shock is delivered to deal with a more serious heart rhythm problem. You might feel as if you're being thumped in the chest.
  • Defibrillation therapy. This is the strongest form of electrical therapy used to restore a normal heartbeat. During this therapy you may feel as if you're being kicked in the chest. It may knock you off your feet. The pain from this therapy typically lasts only a second. There should be no discomfort after the shock is over.

Usually, only one shock is needed to restore a normal heartbeat. Sometimes, however, you may have two or more such shocks during a 24-hour period. Frequent shocks in a short time period are known as ICD storms. If you experience ICD storms, you should seek emergency care to see if your ICD is working properly or if you have a problem that's making your heart beat more abnormally. If necessary, the ICD can be adjusted to reduce the number and frequency of shocks. You may need additional medications to make your heart beat regularly and decrease the chance of an ICD storm.

Who needs an ICD?

You're a prime candidate for an ICD if you've had sustained ventricular tachycardia, survived a cardiac arrest or have fainted from a ventricular arrhythmia. You may also benefit from an ICD if you have:

  • A history of coronary artery disease and heart attack that has weakened your heart.
  • A heart condition that involves abnormal heart muscle, such as enlarged (dilated cardiomyopathy) or thickened (hypertrophic cardiomyopathy) heart muscle.
  • An inherited heart defect that makes your heart beat abnormally. These include long QT syndrome, which can cause ventricular fibrillation and death even in young people with no signs or symptoms of heart problems. Having other rare conditions such as Brugada syndrome and arrhythmogenic right ventricular dysplasia also may mean you need an ICD.
