Hospital develops ablation index to treat atrial fibrillation
EXPERTS from Shanghai General Hospital developed an index to guide doctors doing ablation for patients with atrial fibrillation to standardize the procedure. It is the first such index especially in line with Chinese patients and was named as Shanghai standard by international medical field.
Atrial fibrillation is an abnormal heart rhythm with rapid and irregular beatings. It can result in stroke and heart failure. There are 8 to 10 million patients in the nation and most are elderly people. It has a high fatality and a high rate of disability.
“The usual treatment is medication and ablation, in which doctors help restore patient’s normal heart rhythm by removing or terminating a faulty electrical pathway on the heart through electricity released by a catheter,” said Dr Liu Shaowen, director of Shanghai General Hospital’s cardiology department. “But the duration, force and intensity of ablation are based on doctor’s own feeling and experience. So we developed the index, which is made through computer by calculating all necessary data. Doctors can know when they should stop in according to the rise of the index to ensure treatment effects while avoiding complications.”
The index has been used on patients and received good results. It will be promoted to more domestic hospitals and give a unified standard for doctor training and clinical practice, experts said.
