24 Setrox S Steroid-Eluting Leads Technical ManualThe notch at the side of the stylet guide permits connection of a surgicalcable alligator clip to the lead connector pin for measurement of thecapture threshold and the intracardiac signal. After this, the pacemakeris connected to the lead as described on page 27 and in the appropriatetechnical manual for pacemaker implantation.NOTE:Special care should be taken not to damage the sealing rings ofthe lead connector, particularly when making contact with the ringelectrode of a bipolar lead with an IS‐1 connector (letter designation“BP”) by means of an alligator clip.8.2 Measurement of the Capture Threshold andIntracardiac SignalsLow capture thresholds and adequate sensing of intracardiac signalamplitudes indicate appropriate lead placement. The BIOTRONIK ERA300 Pacing System Analyzer or a comparable device may be used toaccurately determine pacing capture thresholds, as well as intracardiacsignals, in accordance with implant characteristics of implantable pulsegenerators.
Setrox S Steroid-Eluting Leads Technical Manual 25WarningPrevention of Leakage Current ConductionPulse generators and testing equipment connected to thelead must be battery-powered. Proper grounding of linepowereddevices in the vicinity of the patient is essential toprevent leakage currents arising from such devices to beconducted via the lead’s terminal or any other non-insulatedpart.Previously Implanted LeadsIt is generally recommended that a chronically implantedendocardial lead not be explanted. If it becomes necessaryto abandon a lead, the connector pin should be capped toprevent the transmission of electrical signals to the heart.Generally, the electrode position is regarded acceptable if the values forcapture and sensing threshold meet the following industry-recommendedvalues:Measurement Atrial VentricularMaximum acute capture thresholdat pulse duration setting ≤ 0.5 ms1.5 V 1.0 VMinimum acute sensing amplitudes 2.0 mV 5.0 mVImpedance range (0.5 ms, 4.8 V) 500 to 2000 W8.3 Lead Connection to the Pulse Generator1. Withdraw the stylet and stylet guide before connecting the lead tothe pulse generator.2. Lubricate the sealing rings of the lead with the silicone oilcontained within the BIOTRONIK pulse generator package tofacilitate insertion of the lead’s connector into the receptacle ofthe pulse generator without bending the lead.3. Using the pulse generator torque wrench, retract the setscrew(s)counterclockwise far enough to ensure unimpeded insertion ofthe lead connector(s) into the port(s).
