Dr. Usman's Cardiology Notes

I always gets fascinated by the Use of this term accelerated junctional rhythm . I know it’s a very very favourite term of many of the Drs may be because it’s easy to use , easy to remember , but unfortunately not many times its use is not appropriate as per situation. To understand junctional or rhythms originating from junction one needs to understand the anatomy & physiology of the area which is called junction !!!!!!  And this will also help in understanding of terms like junction , junctional escape , accelerated junctional !!!   Generally The terms AV junctional, junctional, AV nodal, and nodal are, however, all essentially synonymous. Tawara(early 19th century) was the to published about AVN and AVJ & and So The thought that the AVJ having a pacemaking function is not at all new!  Definition of AVJ ! Are areas where the atrial myocardium inserts into, and is separated from, the base of the ventricular mass, apart from at the site of penetration of the...

  This ECG is showing typical example of WPW Pattern with Left sided Pathway Look at lead 1  and  V1 for   delta wave and R/S ratio  .After Identifying delta wave look for the polarity of delta wave .If there is iso-electric or negative delta it immediately fixes the pathway in left free wall . Similarly if V1 R >  S it also fixes in left free wall.

  Above video is an example of Ischemic MR. Imagine a vital valve in your heart, responsible for ensuring blood flows in the right direction, suddenly failing due to a lack of oxygen. This is the harsh reality of ischemic mitral regurgitation (IMR), a condition that can lead to catastrophic consequences, including the rupture of a papillary muscle head and prolapse of a leaflet. In this blog post, we'll delve into the world of IMR, exploring its causes, symptoms, and the devastating effects of papillary muscle head rupture and leaflet prolapse. What is Ischemic Mitral Regurgitation? IMR occurs when the mitral valve, located between the left atrium and left ventricle, fails to close properly due to a lack of oxygen (ischemia) in the surrounding heart muscle. This can happen when the coronary arteries, responsible for supplying oxygen-rich blood to the heart, become blocked or narrowed. As a result, the mitral valve leaflets don't close properly, allowing blood to flow backward i...
