Doctors at a British hospital have carried out the first heart rhythm operation using a remote -controlled robot and say its success means patients could be treated by doctors in other cities, or even other countries. Robotic surgery is becoming more common in wealthy nations and can be used on patients suffering from gynecological cancer, coronary artery disease, kidney cancer, and bladder cancer. The procedure carried out by Ng involved inserting thin wires called catheters into blood vessels at the top of the groin and then threading them up into the chambers of the heart.
Electrodes on the catheters record and stimulate different regions of the heart to help the doctor identify the cause of the heart rhythm problem, which usually involves an abnormality in the electrical wiring system of the heart.
Once the area is identified, one of the catheters is placed at the right location to ablate, or burn, the tissue to cure the problem. Catheter ablation has been developed and used over the past two decades effectively in many patients suffering palpitations due to heart rhythm disturbances. They say that remote operations may be carried out on patients in future all over the world.
