surface of the right ventricle rv near the tricuspid valve tv bend 207 may direct catheter 102 toward a catheter portion 208 that substantially conforms to the inner surface of the right ventricle rv along the inferior wall to the apex catheter portion 208 may terminate at a bend 209 located approximately at the apex which directs catheter 102 toward the pulmonary valve pv via a catheter portion 210 catheter portion 210 may substantially conform to the septal wall and extend toward a distal tip 211 of catheter 102 distal tip 211 of catheter 102 may terminate in or around the right ventricle outflow tract at the pulmonary valve pv or within the pulmonary artery this overall catheter configuration including the correspondence between various bends catheter positions and right ventricle geometry may provide stability to catheter 102 and to minimize movement they may also provide reference locations for clinicians so that locations of the various electrodes described below are standardized and facilitate data collection that is robust and comparable between different patients and different patient groups catheter 102 may include a plurality of electrodes for example three to ten or another suitable number of electrodes the electrodes may provide stimulation pulses to the heart tissue measure the tissue response and send the response along the catheter 102 back to a hardware device 104 each electrode may be a pair of electrodes and may be bipolar electrodes although other configurations such as e g monopolar electrodes are also contemplated in some embodiments electrodes may be irregularly spaced about catheter 102 although other configurations including regular spacing are also contemplated in one exemplary embodiment catheter 102 may include eight bipolar sets of electrodes.
