A vertical or slanted bar in each column implies a conduction or depolarization has taken place there. It's a convenient diagram which allows us to see what happened in the conduction system, i.e. what's connected with what, what's not connected ( dissociated), what's blocked, etc. One can have more columns such as a column for SA node, divide AV column into upper and lower AV junction, a column for His bundle, etc. Many ECG text books use this diagram.<br />K.
