The effect of flecainide on the ventricular myocardium causes decreased contractility of the muscle, which leads to a decrease in the ejection fraction. The effect of flecainide on the sodium channels of the heart increases as the heart rate increases; This is known as use-dependence and is why that flecainide is useful to break a tachyarrhythmia.
adenosine, calcium channel antagonists, beta blockers, flecainide AV-nodal reentrant tachycardia ( AVNRT ) is a type of abnormal fast heart rhythm . It is a type of supraventricular tachycardia (SVT), meaning that it originates from a location within the heart above the bundle of His .
WPW syndrome may be monitored or treated with either medications or an ablation (destroying the tissues) such as with radiofrequency catheter ablation. [4] It affects between 0.1 and 0.3% in the population. [1] The risk of death in those without symptoms is about 0.5% per year in children and 0.1% per year in adults. [5]
Now, thanks to a laser ablation, he's seizure free. Brian George worked in a hospital for more than 20 years wondering if a seizure would strike. Now, thanks to a laser ablation, he's seizure free
Catheter ablation is a procedure that uses radio-frequency energy or other sources to terminate or modify a faulty electrical pathway from sections of the heart of those who are prone to developing cardiac arrhythmias such as atrial fibrillation, atrial flutter and Wolff-Parkinson-White syndrome.
Surgical ablation has been used to treat Parkinson's disease. In the 1990s, the pallidum was a common surgical target. Unilateral pallidotomy improves tremor and dyskinesia on one side of the body (opposite the side of the brain surgery), but bilateral pallidotomy was found to cause irreversible deterioration in speech and cognition .
Radiofrequency ablation (RFA), also called fulguration, [1] is a medical procedure in which part of the electrical conduction system of the heart, tumor, sensory nerves or a dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).
There's something about the camera coming on — you come to life. Because right before that, you're not. It's like your dead, and you're revived and it's a "do-or-die" situation.
