Put down the holiday drink and take care of the heart with new guidelines on Afib.
Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. [3] [12] It is a type of supraventricular tachycardia. [14] Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [15]
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.
The heightened level of acetaldehyde this syndrome causes can result in mitochondrial dysfunction, valvular disease, oxidative damage, cell death, lowered effects of cardioprotective molecules, and an altered calcium transport and protein synthesis system. [4] If left untreated, it can result in thrombosis, pneumonia, cirrhosis, and heart failure.
Niacin may raise heart disease risk, a study finds. Experts share what you need to know about vitamin B3 and its potential to trigger inflammation.
Those who have severe symptoms from an arrhythmia or are medically unstable may receive urgent treatment with a controlled electric shock in the form of cardioversion or defibrillation. [6] Arrhythmia affects millions of people. [4] In Europe and North America, as of 2014, atrial fibrillation affects about 2% to 3% of the population. [9]
All these ECG-based technologies also enable the distinction between AVNRT and other abnormal fast heart rhythms such as atrial fibrillation, atrial flutter, sinus tachycardia, ventricular tachycardia and tachyarrhythmias related to Wolff-Parkinson-White syndrome, all of which may have symptoms that are similar to AVNRT. [citation needed]
There are two major classes of cardiac fibrillation: atrial fibrillation and ventricular fibrillation. Atrial fibrillation is an irregular and uncoordinated contraction of the cardiac muscle of atria. It can be a chronic condition, usually treated with anticoagulation and sometimes with conversion to normal sinus rhythm.
