Simulations of real systems make it possible to test “what if” questions, and compare the results with what did happen. For example, I am working on a study in which a stimulus pulse turns on and off while a spiral wave rotates about an obstacle. We can ask, “What happened to the spiral wave following [...]

We do a lot of really cool and scientifically interesting stuff in both our lab and the field as a whole. We have now developed our technology to the point where we can take an MRI scan of a heart and develop a complete model, with accurate fiber directions from diffusion tensor data, in a [...]

Nearly one year ago, I raised some questions about the safeguards present on ICDs and pacemakers, especially given the expansion of longer-range (”wandless”) telemetry.
Now a group of researchers has gotten access to a device without the normal accompanying computer hardware, normally called a “programmer”. They do note that it required expensive equipment at a [...]

Clinical Cases and Images has a nice post up with a set of links to and explanations of various ECG/EKG learning tools. They are introduced as follows:

To provide some background, I am a teaching attending at Cleveland Clinic and have multiple rotations during the year with our residents and medical students. We record all topics [...]

I recently discovered an interesting piece of open-source software, the CESE single-cell simulator. It’s based on Java and runs on a number of platforms.
The point of this simulator is strictly to run single-cell electrophysiological models. It comes with a few of the staples in the field (like the Luo-Rudy dynamic model), and you can [...]
