Cardiac optogenetics achieve defibrillation without the pain of electric shocks
The first evidence for a shockless treatment for atrial fibrillation (AF) will be presented today at Frontiers in CardioVascular Biology (FCVB) 2014 in Barcelona, Spain. The meeting is organised by the Council on Basic Cardiovascular Science of the European Society of Cardiology (ESC) in collaboration with 13 European cardiovascular science societies.http://spo.escardio.org/SessionDetails.aspx?eevtid=65&sessId=13104
Dr Brian O. Bingen, first author, said: “AF is the most common cardiac arrhythmia. Symptoms range from the feeling of fish flapping in the chest, to tiredness and exercise intolerance. AF can lead to tachycardia induced cardiomyopathy and thromboembolic events which increase the risk of morbidity and death.”
He added: “Preventing these symptoms and complications requires bringing the patient out of AF and back to the normal sinus rhythm. The quickest way to do that is to deliver an electric shock. The shock depolarises and synchronises the heart muscle and allows the sinus node to re-establish a normal rhythm.”
“This is the first evidence of a shockless defibrillation. Our method of using optogenetics to defibrillate by light is completely painless and looks promising but more research is needed before it can be applied in patients.”
