Pulmonary Disease

• Chronic Obstructive Pulmonary Disease
• COPD disease of the lungs with airway
  obstruction, chronic bronchitis and emphysema
• Cigarette smoking results in PACs, 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 MIs

Hypothermia

• Core body temperature of lt 95 degrees
• Distinctive narrow positive wave the Osborn
  wave/J wave/J deflection/camels hump

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
