CHAPTER 5 PRESENTATION

  1. 1. AngiographyDOPPLER ULTRASONOGRAPHY&STRESS TESTING<br />OLEVIER BRUNSON<br />
  2. 2. THE HUMAN HEART<br />
  3. 3. ANGIOGRAPHY<br />An angiogram is an X-ray test that uses a special dye and camera to take pictures of the blood flow in an artery or a vein. An angiogram can be used to look at the arteries or veins in the head, arms, legs, chest, back, or belly.<br /><ul><li>An angiogram can find a bulge in a blood vessel
  4. 4. It can also show narrowing or a blockage in a blood vessel that affects blood flow.
  5. 5. And an angiogram can show if coronary artery disease is present and how bad it is.</li></li></ul><li>ANGIOGRAPHY<br />This technique was first developed in 1927 by a Portuguese physician and neurologist Egas Moniz<br />Major complications are rare but may include:<br /><ul><li>Blood clots
  6. 6. Hypotension
  7. 7. Blood vessel damage on the route to the heart from the catheter </li></li></ul><li>DOPPLER ULTRASONOGRAPHY<br />Doppler ultrasonography is a non-invasive diagnostic procedure that changes sound waves into an image that can be viewed on a monitor<br />Doppler ultrasonography can detect the directionand speed of blood flow.<br />It is also used to detect problems with heart valves <br />Also for viewing the heart to monitor carotid artery diseases<br />Its also used to evaluate blood flow in the abdomen or legs<br />
  8. 8.
  9. 9. Doppler ultrasound of Artery<br />
  10. 10. STRESS TESTING<br />A stress test is a medical test that indirectly reflects arterial blood flow to the heart during physical exercise. When compared to blood flow during rest, the test reflects imbalances of blood flow to the heart's left ventricular muscle tissue – the part of the heart that performs the greatest amount of work pumping blood<br />
  11. 11. The first standardized cardiac stress test was developed in 1929 by Arthur Master, <br />The patient either walks on a treadmill or is given IV medication that simulates exercise while connected to an electrocardiogram machine. The level of exercise is increased every 3-minute. The patient's symptoms and blood pressure response are repeatedly checked. When using ECG and blood pressure monitoring alone the test is variously called a cardiac stress test, exercise stress test, exercise treadmill test, exercise tolerance test, stress test or exercise ECG test.<br />
  12. 12. Both the resting and stress images show uniform uptake through out the heart<br />
  13. 13. LIFE BEGINS AND ENDS WITH ONE BEAT OF THE HEART!!<br />
