Implantation of Pacemaker / Cardioverter Defibrillator
Pacemaker is a small battery operated computer that can be implanted inside the body to correct slow heart rate problems. The implantation procedure is usually done under local anesthesia and the device is generally implanted under the skin below the collarbone and is connected to the heart via one or more pacing leads.
An implantable cardioverter defibrillator is a device that can generate electrical shocks to correct fatal arrhythmias. It can also act as a pacemaker if slow heart rate is detected. In general, the device is implanted in a similar way as a pacemaker.
Electrophysiological Study / Radiofrequency Ablation
An electrophysiology study is a special catheterization test in which electrode catheters are put inside the heart, usually via the femoral veins in the groins, to study the cardiac electrical system. The procedure is carried out under local anesthesia to check out cardiac arrhythmias.
Radiofrequency ablation is a procedure that utilizes a special electrode catheter to deliver radiofrequency energy to cauterize culprit areas within the heart that are responsible for the arrhythmias. It is carried out in the same procedure, immediately after the baseline electrophysiology study.
