Document Summary
These sequences are qrs signals that are not generated by the nodes, but are caused by the ventricular muscles. This is a signal of a clot in the heart, forcing blood into a ventricle. Defibrillation uses a high current to force the heart to start working again, since this forces all heart cells to recalibrate itself, to become in sync again. Mapping of the cardiac electrical activity: directly attach electrodes onto a heart, on the epicardial surface. The computer would then map of how the heart muscles activate by their order. Or using endocardial balloon inside of a heart to measure it. Circus movement re-entry is when an anatomical obstacle inside of the heart blocks the action potential from cycling through the heart. The cmr was discovered by mines, who died in 1914 at the age of 27. Spiral-wave re-entry is when no obstacle is present, and the re-entry continues on in a spiral.
