National Center for Cardiovascu- Gene assaying for inherited cardiac arrhythmia a Chinese consensus. lar Diseases Fuwai Hospital Beijing China Abstract In 2011 based on worldwide research progress and opinions experts of Chinese Society of Cardiology Chinese Medical Association and Editorial Board of Chinese Journal of Cardiology issued the 2011 China Expert Consensus Statement on Genetic Testing for Cardiac Channelopathies and Cardiomyopathies. The statement mostly delineated the impacts of genetic testing on the diagnosis prognosis treatment and prophylaxis of inherited cardiac arrhythmia and has offered instructions for genetic testing in China.
