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 ...

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 ...

Note the gradual onset of the junctional mechanism as the sinus cycle length increases from 635-670 milliseconds while the ectopic rhythm usurps the sinus rhythm at a more rapid cycle length of ...

Samuel Bergman, graduate research assistant at The Johns Hopkins University, discusses his abstract about establishing a complete atrioventricular block in porcine models, which was the topic of his ...

Anterior nasal packing was unsuccessful in achieving haemostasis. After the exchange of devices and insertion of a posterior nasal pack, the patient developed a junctional rhythm and progressively ...

OBJECTIVE To examine the cycle length of the junctional tachycardia often seen during successful slow pathway ablation for atrioventricular (AV) node re-entrant tachycardia, to determine whether ...
