Presentation Transcript

  1. Cardiovascular System Clinical Day

  2. Hemopoietic Growth Factors

  3. Red blood cells removed and stored Reinjected a few days before an athletic event Shown to improve endurance events (more oxygen to body) Dangerous practice as heart load increased (thicker blood) Induced Erythrocythemia "Blood Doping"

  4. Artherosclerosis

  5. One or more bypass grafts are implanted between the aorta and the coronary blood vessel Saphenous veins (from the leg) or arteries (like the IMA = internal mammary artery) are commonly used as grafts Coronary Bypass Surgery

  6. Valve Disorders

  7. Tetralogy of Fallot- four different heart defects: Ventricular septal defect (VSD)- hole between ventricles of the heart. Pulmonary Stenosis- narrowing at or just below the pulmonary valve Aorta positioned over the ventricular septal defect instead of in the left ventricle Right ventricle is more muscular than normal Blue Baby

  8. Former Student

  9. Ductus arteriosus- temporary vessel between aorta and pulmonary trunk Normally closes shortly after birth Remains open increasing pressure and overworks both ventricles Patent Ductus Arteriosus

  10. Interatrial- between atria Interventricular- between ventricles Septal Defect

  11. Pacemakers

  12. Heart block: beat “blocked”- different degrees Diminished blood flow Flutter- Rapid atrial contractions followed by AV block Tachycardia- rapid heart rate (over 100) Brachycardia- slow heart rate (under 60) Arrhythmias

  13. Fibrillation- asynchronous contraction of atrial (reduces effectiveness 20-30%) or ventricular muscle (very serious) Arrhythmias

  14. Varicose Veins
