3-D Cardiac Mapping
Cardiac mapping is the process of collecting and displaying information gathered from cardiac electrograms. A grid was originally used to represent velocity and amplitude of surface ECG’s. By knowing how the grid was set up could derive a good deal of information from the lines of the electrocardiogram.
With the advent of computer technology, medical inventors have furthered the capabilities both the recording and display of cardiac electrograms. The systems of today have advanced these functions to the point where the entirety of electrical activation within a single chamber can be recorded and displayed in a single beat. This section of The EP Lab will look at how the cardiac mapping systems function.
