563 Possible Causes for Cardiogenic Syncope, Focal Atrophy of Choroid, Prolonged PR Interval

  • Sick Sinus Syndrome

    This occurs in 50% of people and this is a form of neuro-cardiogenic syncope. [1] [3] [5] fatigue and Weakness [1] Due to inadequate blood supply from the heart to meet the[explainmedicine.com] Pronounced PR interval prolongation. The effect of this PR interval prolongation on AV dyssynchrony is demonstrated in this ECG image.[emedicine.medscape.com] What is the overlap between sinus node dysfunction and neuro cardiogenic syncope ? SND can occur as an overlapping syndrome with neurocardiogenic syncope.[drsvenkatesan.com]

  • AV Block Mobitz II

    Commonly used terminology includes: First degree AV block – Delayed conduction from the atrium to the ventricle (defined as a prolonged PR interval of 200 milliseconds) without[uptodate.com] Every-other-P wave conducts – as determined by the presence of a fixed ( albeit prolonged ) PR interval preceding each QRS complex on the tracing.[ecg-interpretation.blogspot.com] In this variant of second degree heart block the PR interval is constant with occasional dropped beats as compared to the gradually prolonging PR interval in Mobitz type I[wikidoc.org]

  • Patent Ductus Arteriosus

    The hemodynamic effects of a patent ductus arteriosus (PDA) are well known including systemic hypoperfusion and volume overload on the left ventricle. This article aims to provide a review of the long-standing effect of a hemodynamically significant PDA on the pulmonary vasculature and the role of cardiac[…][ncbi.nlm.nih.gov]
