contact with terminal 223 and that an electrical isolation of terminal 222 is provided at the same time since terminal 225 has been moved away from it such an arrangement would permit left ventricular pacing finally the abstract wiring diagram 303 of fig3 c demonstrates that when modes selection button 244 is depressed a simultaneous electrical connection between terminals 222 223 and 225 is provided resulting in a branched negative lead within the pacing cable as shown in wiring diagram 303 of fig3 c such an arrangement would permit biventricular pacing with regard to fig4 transthoracic placement of three cardiac pacing leads is shown two on the right ventricular epicardium and one on the left ventricular epicardium lead 401 is a positive pacing lead lead 402 is the negative pacing lead for the right ventricle and lead 404 is the negative pacing lead for the left ventricle pacing leads 401 402 and 403 are lead away from the heart and through the skin of the patient in order to provide the conductive path necessary for temporary cardiac pacing it has been observed that one positive pacing lead placed on the heart on either ventricle will provide an adequate return path for right ventricular left ventricular and biventricular pacing the features of another pacing cable in accordance with the present application will be shown with reference to fig5 a 6 b and 6 c some terminals mentioned below are not visible in fig5 because they are enclosed within the pacing cable 500 but all terminals are depicted either by solid or dashed lines in the pacing cable wiring diagrams 601 602 and 603 shown in fig6 a 6b and 6 c respectively the pacing leads 401 402 and 403 shown in fig4 are attached respectively to terminals 501.
