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

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

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

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
