“…Smaller endocardial pacing poles have been shown to create a smaller but more intense electrical field and this property is likely to apply to esophageal pacing poles as well. 10,17 The results of this study cannot be used to effectively discriminate between the individual importance of polar surface area and catheter shape. As such, further investigation is necessary in order to fully understand what effects polar surface and catheter shape may have on the efficacy of TAP.…”

“…10,11 Note that in order to obtain optimal results, each pacemaker manufacturer supplies PSAs with band-pass filters that match the filters used in their pacemaker systems. 1 PSA cable connections (Medtronic model 5833SL of 3.66 m length and St. Jude Medical model 4051 L of 3.7 m length, respectively) were used to display the EGM through the implanted RV lead in bipolar mode by using crocodile clips on the lead terminal pins. Sensing measurements were taken through PSA after helix extension of the active fixation RV lead.…”

“…(PSA) unit. 1 The PSA application displays real-time signals for surface electrocardiogram (ECG), generates sensing markers for local EGM, and outputs those signals to a recorder as well. Following implantation, the implanted pulse generator is expected to replicate the sensing data obtained during the PSA operation.…”

“…Sensing in pacemaker therapy means the ability of the device to recognize the heart’s intrinsic signal through the implanted lead by analyzing the local endocardial electrogram (EGM) with specific reference to the QRS on the surface electrocardiogram (ECG). 1 Knowledge of the time course of the propagation of right ventricular (RV) electrical activation during intrinsic conduction is of great value for the understanding of ventricular sensing. With endocardial electrode catheters, early studies have demonstrated significant differences in the time of ventricular activation at the different RV anatomical locations, including early septal excitation starting at the left ventricular side and spreading to the right, activation of the RV apex before the RV outflow tract, and delayed RV activation in the presence of complete right bundle branch block (RBBB).…”
