Teaching electrocardiogram interpretation

摘要: The subject addressed here permits me to acknowledge my teachers and mentors in electrophysiology electrocardiography. first of these is Robert Grant, known only through his magisterial book on spatial vectorelectrocardiography. Electrocardiograms (ECGs) could be displayed as 3-dimensional arrows, which are quite difficult draw. His technique sprung out contemplation the standard 12-lead tracing. But simultaneously, vectorcardiography photographed from an oscilloscope a 3-plane interrupted vector loop was being hatched into limited clinical practice. There were opposing advocacies for cube, tetrahedron, Frank system—the latter remaining victorious. In some degree, oscilloscopic approach concepts blunted Grant’s influence. A later reason neglect approach: echocardiography. It seemed promise localization lesions or infarcts heart. real marriage partner vector-electrocardiography should come with fruition cardiac magnetic resonance imaging. My personal mentor David Littmann Boston, whose forte ST segment T wave. Next came Hans Hecht, who made cellular potentials subjects discussion opposed remote bench inquiry. He I became deeply involved redefinition AV junction. year Gordon Moe Carlos Mendez brought life such notions electrotonic effect, cumulative effect frequency, functional block, electrical occlusion conducting pathway, supernormality, various types refractory period. acquired enormous respect Mexican contributions both electrocardiography research techniques (such double-dog preparation Jesus Alanis). Alfred Pick Richard Langendorf 9 taught rhythm analysis concealed conduction. spent splendid sabbatical Paris Phillipe Coumel, studying atrial vulnerability Patrick Attuel.
