Heart Rhythm Services - EPS, Ablation, Devices

Is conducted in a cardiac electrophysiology lab and looks at how well the “electrical circuitry” of the heart works and whether a fast heart rhythm (arrhythmia) can be started.

Is a procedure that uses Radiofrequency or Freezing energy to remove small areas of heart tissue that cause abnormally fast heart rhythm (arrhythmia). 

Procedures include ablation of Atrial Flutter, Arial Tachycardia, AVNRT, Accessory pathways, Atrial Fibrillation, Ventricular Tachycardia.

Over the years, Dr.Choudhury has experience of catheter ablation using Stereotaxis and Hansen technologies for his Complex ablation cases.

Is a small device that sends electrical impulses to the heart to keep the heart beating at a normal rate. There is a generator (battery) and lead(s) which sit under the skin on the left or right side of the chest.

Is a device that treats life-threatening abnormal fast heart rhythms by either pacing the fast heart rhythm away or if required delivering an electric shock. There is a generator (battery) and lead(s) which sit under the skin on the left or right side of the chest. It continuously monitors your heart beat.

Is a device that resynchronises a weak heart with abnormal conduction (left bundle branch block) and is associated with improved heart pump function. There is a generator (battery) and lead(s) which sit under the skin on the left or right side of the chest. It continuously monitors your heart beat.

We can perform routine checks on your device to ensure that it is working appropriately and that there is sufficient residual battery life.

Most ICD's and CRT's have remote monitoring features, that records any undesired cardiac conduction events and transmit to the device clinic over telephone and internet, which are then analysed and if needed the patient gets a call about the event, and further instructions are given regarding the management of the episodes. This technology gives us the ability to get to patients undergoing life threatening events at the earliest.

Is a small device which is the size of a USB stick. It sits underneath the skin on the left side of the chest. It continuously monitors your heartbeat. The ILR is a useful diagnostic tool when patients experience symptoms such as syncope (fainting), seizures, recurrent palpitations, lightheadedness, or dizziness regularly but not often enough to be captured by a 24-hour or 30-day external monitor. Because of the ILR's long battery life (up to 3 years), the heart can be monitored for an extended period.

For certain suspected conditions like Brugada Syndrome, CPVT, LQT, etc we sometimes perform cardiac electrophysiology study while administering certain drugs that might provoke certain arrhythmias if the patients have those conditions. It is done in controlled environment and can be terminated at any point if required.

These are procedures that are performed by cardiac electrophysiologists along with Cardiac surgeons who perform minimally invasive procedure without the need of an open chest.  Conditions such as Brugada Syndrome arrhythmias, persistent Atrial Fibrillation, Inappropriate Sinus Tachycardia, etc usually are candidates for this procedure.

At times an angiogram might be necessary during a procedure just before the ablation to make sure that we are maintaining a safe distance to the arterial system in the heart. The access is usually through the wrist (radial artery).
