Abstract
A heart electrode placement unit has a pair of displays, one for an intercardiac electrocardiogram and a second for an external sensed electrocardiogram. A pacing unit is releasably secured to the placement unit by a plug-in connector having a switch normally connecting a pulse source to electrode leads. The placement connector part is connected to a switch to connect the electrode directly to the input of the one display or reconnect the electrode leads to the pulse source. When the connector is open, the pacing switch automatically closes to reconnect the pulse source to the electrode leads.
