Fast NIR Probes for Optical Electrophysiology Current problem Optical imaging of myocardial tissue is traditionally done by using either branch electrodes, or high voltage sensitive dye. Both of these mapping procedures have significant drawbacks. Using branch electrodes to map the myocardial tissue is problematic because several needles have to be inserted into the heart, causing damage...
