Presentation Transcript

  1. Pulmonary Disease • Chronic Obstructive Pulmonary Disease • COPD disease of the lungs with airway obstruction, chronic bronchitis and emphysema • Cigarette smoking results in PAC’s, WAP, A-flutter, A-Fib • P Pulmonale • Acute Pulmonary Embolism • Blood Clot or other foreign matter lodges in a PA causing obstruction of blood flow to lungs • Originate from deep leg veins/pelvic veins • Chronic Cor Pulmonale • Enlargement of RV with RHF end stage results of Pulmonary Hypertension

  2. Early Repolarization • A term used to describe a form of Myocardial repolarization in which the ST segment is elevated or depressed 1-3 mm above or below the base line. • Seen in Acute MI’s

  3. Hypothermia • Core body temperature of < 95 degrees • Distinctive narrow positive wave the Osborn wave/J wave/J deflection/camel’s hump • Occurs at the junction of the QRS complex and ST segment

  4. Preexcitation Syndromes • Accessory AV pathways (bundle of Kent) • Wolff-Parkinson White conduction • AV pathway between the Atrial and Ventricle bypasses the AV junction • Delta Wave • Atrio-His fibers (James fibers) • Atria with the lowermost part of the AV node bypassing the slower conducting AV node. • Atrio-His preexcitation • Nodoventricular fibers (Mahaim fibers) • Lower part of the AV node to the ventricles • Ventricular preexcitation
