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]
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.
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.

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.
Over 99% of individuals in the general population will have at least one PAC in a 24-hour period. [6] Many PACs can indicate increased risk of atrial fibrillation and/or ischemic stroke . [ 6 ] The threshold for number of PACs which substantially raises the risk atrial fibrillation is debatable, but some estimates range between in excess of 500 ...
The most common cause of sudden death in the US is coronary artery disease specifically because of poor oxygenation of the heart muscle, that is myocardial ischemia or a heart attack [15] Approximately 180,000 to 250,000 people die suddenly of this cause every year in the US. SADS may occur from other causes.
