  1. PotentiometricHeart Mapping10/26 – 11/09

  2. Continue to compile, sort and analyze the data that was acquired over the summer • Develop new experimental models and potential pursuits • Saline bath model • Rabbit heart model The past two weeks…

  3. Some instrumentation redesign and repair is needed to execute these two models. • The heart stim catheter needs to be redesigned to • increase usability • Increase reliability • More ergonomic • An ammeter with sufficient sensitivity will need to be designed to measure current. • Consider size restrictions • 1mV to 25mV supplied voltage • Ergonomic • Doesn’t necessarily have to be numerical but • sensitive enough to detect current variations • throughout a volume Design…

  4. Purchase or acquire any of the necessary materials in order to correctly build/rebuild the two devices • Design, test and redesign the cathode and ammeter for optimum usability • Execute the saline bath experiment to calibrate the equipment and determine if pursuing the live model is valid • Write a proposal for funding for live model experiment • With sufficient funding execute the live model experiment • Compile data and analyze The Next few Days…
