A junctional rhythm occurs when the electrical activation of the heart originates near or within the atrioventricular node, rather than from the sinoatrial node. Because the normal ventricular ...

In the authors' experience, junctional rhythm and successful modification is achieved by approximately 90% during the first radiofrequency application at the point of the intersection. An example ...

His lungs are clear to auscultation. The rest of his exam is normal. A junctional rhythm occurs when the sinoatrial node (SA node) is not able to generate an action potential and the ...

In the NORMO group, one patient had a persistent accelerated junctional rhythm associated with prolonged hypotension. This arrhythmia was missed at the bedside, and it was only identified ...
