Mechanically induced Roemheld syndrome is characterized by pressure in the epigastric and left hypochondriac region. Often the pressure is in the fundus of the stomach, the esophagus or distention of the bowel.
Experimental studies observed that activating autoantibodies to the beta1/2-adrenergic and M2 muscarinic receptors are associated with atrial tachyarrhythmias in patients with hyperthyroidism. [15] Additional research into the prevalence of these biomarkers in Grave's disease (grave's hyperthyroidism) showed facilitated triggering of pulmonary ...
HAS-BLED is a scoring system developed to assess 1-year risk of major bleeding in people taking anticoagulants for atrial fibrillation (AF). It was developed in 2010 with data from 3,978 people in the Euro Heart Survey. [1] Major bleeding is defined as being intracranial bleedings, hospitalization, hemoglobin decrease > 2 g/dL, and/or transfusion.
Fibrillation can affect the atrium (atrial fibrillation) or the ventricle (ventricular fibrillation): ventricular fibrillation is imminently life-threatening. Atrial fibrillation affects the upper chambers of the heart, known as the atria. Atrial fibrillation may be due to serious underlying medical conditions and should be evaluated by a ...
Atrial fibrillation: Red dots show atrial fibrillation activity. Atrial fibrillation meets the definition of SVT when associated with a ventricular response greater than 100 beats per minute. It is characterized as an "irregularly, irregular rhythm" both in its atrial and ventricular depolarizations and is distinguished by its fibrillatory ...
risk of stroke (for non-rheumatic atrial fibrillation) The CHADS 2 score and its updated version, the CHA 2 DS 2 -VASc score , are clinical prediction rules for estimating the risk of stroke in people with non-rheumatic atrial fibrillation (AF), a common and serious heart arrhythmia associated with thromboembolic stroke.
Arrhythmias can also occur, most-commonly atrial fibrillation (incidence of 20–40%) that is treated with correcting electrolyte balance, and rate and rhythm control. [42] [38] However, arrhythmia such as ventricular tachycardia or fibrillation can be a sign of postoperative myocardial ischemia that is treated depending on the cause. [48]
The left atrial appendage is a pouch-like structure located in the upper part of the left atrium. [1] Left atrial appendage occlusion (LAAO) is an alternative therapy to oral anticoagulation in a certain subset of patients with atrial fibrillation. Atrial fibrillation is characterized by an irregular and uncoordinated pumping function of the atria.
