The spike of an "atrial-demand pacemaker" appears just before the P wave. [16] Comparably, a Triggered Pacemaker is activated immediately after an electrical activity is commenced in the heart tissue by itself. A "ventricular triggered pacemaker" produces the impulse just after a pulse is created in the ventricular tissue and it appears as a ...
Rotation of the catheter to a "home view" of the left atrium through the mitral valve into the left ventricle. From there, a 180° rotation will face the posterior wall and posterior deflection will bring the left atrial appendage into view and can be used for deployment of a left atrial appendage occlusion device.
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.

Not only the pulmonary vein, but the left atrial appendage can be a source of atrial fibrillation and is also ablated for that reason. [17] As atrial fibrillation becomes more persistent, the junction between the pulmonary veins and the left atrium becomes less of an initiator and the left atrium becomes an independent source of arrhythmias. [18]
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.
An artificial cardiac pacemaker (or artificial pacemaker, so as not to be confused with the natural cardiac pacemaker) or just pacemaker is an implanted medical device that generates electrical impulses delivered by electrodes to the chambers of the heart either the upper atria, or lower ventricles to cause the targeted chambers to contract and ...
