Patient tissues are imaged using, e.g., a real-time fluoroscopic imaging system, along with a lead system being implanted. Parameters representative of lead placement efficacy—such as capture thresholds, phrenic nerve stimulation thresholds, impedance values or screw-in tip mechanical resistance values—are measured at candidate implant locations. Localization parameters identifying the candidate implant locations are also measured. In one example, a display is generated substantially in real-time showing: images of the tissues of the patient and the lead system being implanted; candidate locations of the electrodes; and parameters representative of lead placement efficacy at the candidate locations. In this manner, the implanting clinician can readily view capture thresholds and other helpful parameters at various candidate locations along with actual real-time images of the tissues of the patient and the lead system being implanted. Recorded images can also be displayed and, in some examples, multiple images can be superimposed over one another. |
