Cardioneuroablation
A frequent type of syncope, termed vasovagal syncope is originated by intense cardioinhibition, mediated by a sudden vagal reflex, that causes transitory cardiac arrest by asystole and/or transient total atrioventricular block. It is known as “Vaso-vagal Syncope”, “Neurocardiogenic Syncope” or “Neurally-mediated Reflex Syncope”. Although many different therapies have been tried in this condition, severe and refractory cases have been treated with pacemaker implantation despite great controversies about its benefit. The “Cardioneuroablation” is a technique created in the nineties and patented in United States, USA, aiming to eliminate the cardiac branch of vagal reflex in order to treat the neurocardiogenic syncope without pacemaker implantation. It is performed without surgery, by using radiofrequency catheter ablation with one-day hospital. The results up to 100 months follow-up are showing better outcome than clinical measures or pacemaker implantation with chang ...

Vasovagal Syncope
Reflex syncope is a brief loss of consciousness due to a nervous system, neurologically induced drop in blood pressure and/or a decrease in heart rate. Before an affected person passes out, there may be sweating, a decreased ability to see, or tinnitus, ringing in the ears. Occasionally, the person may twitch while unconscious. Complications of reflex syncope include injury due to a fall. Reflex syncope is divided into three types: vasovagal, situational, and carotid sinus. Vasovagal syncope is typically triggered by seeing blood, pain, emotional stress, or prolonged standing. Situational syncope is often triggered by urination, swallowing, or coughing. Carotid sinus syncope is due to pressure on the carotid sinus in the neck. The underlying mechanism involves the nervous system slowing the heart rate and dilating blood vessels, resulting in low blood pressure and thus not enough blood flow to the brain. Diagnosis is based on the symptoms after ruling out other possible c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
