Put down the holiday drink and take care of the heart with new guidelines on Afib.
Atrial fibrillation (AF, AFib or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by rapid and irregular beating of the atrial chambers of the heart. [11] [12] It often begins as short periods of abnormal beating, which become longer or continuous over time. [4]
The underlying anatomical causes of PSVT, specifically atrioventricular nodal reentry, involve the presence of two functionally distinct conduction pathways within the AV node and the formation of a reentrant circuit that sustains the tachycardia. [8] These pathways within the AV node are known as the fast pathway and the slow pathway. [9]
Atrial fibrillation and atrial flutter resulted in 112,000 deaths in 2013, up from 29,000 in 1990. [10] However, in most recent cases concerning the SARS-CoV‑2 pandemic, cardiac arrhythmias are commonly developed and associated with high morbidity and mortality among patients hospitalized with the COVID-19 infection, due to the infection's ...
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 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.
Recovery from a reflex syncope episode happens without specific treatment. [2] Prevention of episodes involves avoiding a person's triggers. [2] Drinking sufficient fluids, salt, and exercise may also be useful. [2] [4] If this is insufficient for treating vasovagal syncope, medications such as midodrine or fludrocortisone may be tried. [4]
NPPA variants affect plasma ANP concentrations, blood pressure levels, and cardiovascular diseases such as atrial fibrillation (AF). [11] ANP-deficient mice were found to have a large increase in heart and left ventricular weight in response to volume overload, which is normally prevented by proper regulation of blood pressure.
