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.
A single chamber ICD with its right ventricular lead connected into the header; note, starting from the end of the lead, the tip and adjacent first ring, used to sense the cardiac electrical activity and stimulate the right ventricle, the coil and the two rings for atrial sensing. On average ICD batteries last about six to ten years. [2]
The Cox maze procedure, also known as maze procedure, is a type of heart surgery for atrial fibrillation. "Maze" refers to the series of incisions arranged in a maze -like pattern in the atria . Today, various methods of minimally invasive maze procedures, collectively named minimaze procedures , are used.
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]
Synchronized electrical cardioversion is used to treat hemodynamically unstable supraventricular (or narrow complex) tachycardias, including atrial fibrillation and atrial flutter. It is also used in the emergent treatment of wide complex tachycardias, including ventricular tachycardia, when a pulse is present.
The types of SVT associated with TIC include atrial fibrillation, atrial flutter, incessant atrial tachycardia, permanent junctional reciprocating tachycardia, atrioventricular reciprocating tachycardia, and atrioventricular nodal reentry tachycardia. [1] Atrial fibrillation is the most common and well-studied etiology of TIC. [1] [5]
A new study found that atrial fibrillation — an irregular heartbeat that's one of the most common causes of stroke — is more prevalent than previously thought. This heart condition is 3 times ...
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.
