Transcript of "Fl Electrophysiologis Rpt"

  1. 1. Taser Device: A Cardiac Electrophysiologist’s Perspective Aurelio Duran MD Orlando Heart Center
  2. 2. <ul><li>Cardioloigist/Electrophysiologist </li></ul><ul><li>Cardiology Advisor Orange County EMS </li></ul><ul><li>Vice Chairman Cardiology ORMC </li></ul><ul><li>Teach house staff at ORMC and FSU Medical students </li></ul><ul><li>Help develop pacemakers and defibrillators </li></ul>
  3. 3. Electricity and our bodies <ul><li>Used by our bodies to perform many functions. </li></ul><ul><li>Rapid messenger-working in msec </li></ul><ul><li>Manipulating the electrical status of cells can have major impact as to how the body functions. Many uses in medicine. </li></ul>
  4. 4. How “electricity” is normally used
  5. 5. How “electricity” is normally used
  6. 6. How “electricity” is normally used
  7. 7. How “electricity” is normally used
  8. 8. How “electricity” is normally used
  9. 9. How “electricity” is normally used <ul><li>Specialized electrical cells act as wires </li></ul><ul><li>Nerves, heart, muscle </li></ul><ul><li>Very small amounts of current are needed to trigger conduction from cell to cell-dependant on voltage </li></ul>
  10. 10. Chemical Electrical Gates <ul><li>Work instantaneously- on/off like a light switch </li></ul><ul><li>Altering these systems are widely used in many medical and non medical situations </li></ul><ul><li>Medications-anesthetics, anti-arrhythmics, and anti-seizure drugs </li></ul>
  11. 11. Chemical Electrical Gates <ul><li>Pacemakers </li></ul><ul><li>Defibrillators </li></ul><ul><li>Skin stimulator to measure depth of anesthesia </li></ul><ul><li>Tens Units </li></ul><ul><li>“ Muscle building” devices home use </li></ul><ul><li>Taser </li></ul>
  12. 12. Chemical Electrical Gates <ul><li>Activation naturally or artificially does not damage these cells </li></ul><ul><li>Conduction with these methods is driven by voltage not current </li></ul><ul><li>Voltage changes are the natural method in which these cells “talk” to each other </li></ul><ul><li>High voltage activates these systems without damage to cells. High current is what could burn or “cook” tissue-electrocution </li></ul>
  13. 13. Taser <ul><li>High voltage low current system </li></ul><ul><li>Fixed current </li></ul><ul><li>Small electrodes which are superficial </li></ul><ul><li>The amount of energy delivered to the skin is very small 3.8 mA </li></ul><ul><li>Range of what is used directly on the heart in pacemakers </li></ul>
  14. 14. What would the “ideal” bad device look like <ul><li>High current </li></ul><ul><li>Large electrodes/deep/?gel-penetrate high resistance of skin/chest/lungs </li></ul><ul><li>Front and back electrodes-not on the same side of body </li></ul><ul><li>This “bad” device would need these features to be able to get the current to the heart which is insulated </li></ul>
  15. 15. Taser <ul><li>Does not appear to be able to do this </li></ul><ul><li>Observations-volunteers 50,000, animals, real use </li></ul><ul><li>If a device were to cause a bad rhythm (ventricular fibrillation or ventricular tachycardia) the individual would collapse and arrest immediately </li></ul><ul><li>Not seen </li></ul>
  16. 16. Taser <ul><li>Works by instantly interfering with the nervous systems ability to send messages </li></ul><ul><li>Not likely to be able to have electricity reach the heart </li></ul>
