“…10 In this study, capture threshold was lowest with the lead located in the RV apex with a median threshold of 0.8 mA and the ECG had a consistent "qR" morphology in channel 3. This is similar to the target threshold of <1 mA in people, 5,43 and further supports the RV apex as the optimal placement location.…”

BackgroundThe ability to perform transvenous temporary cardiac pacing (TV‐TP) is critical to stabilize horses with symptomatic bradyarrhythmias. Reports of successful TV‐TP in horses are limited, and only briefly describe short‐term pacing.ObjectiveTo describe temporary, medium‐term (24 h) transvenous right ventricular pacing in awake horses using a bipolar torque‐directed pacing catheter.AnimalsSix healthy adult institutional teaching horses.MethodsProspective experimental study with 2 immediately successive TV‐TP lead placements in each horse with a target location of the RV apex. One placement was performed primarily with echocardiographic guidance and 1 primarily with fluoroscopic guidance. In all placements, corresponding images were obtained with both imaging modalities. Horses were then paced for 24 h, unrestricted in a stall with continuous telemetric ECG monitoring. Echocardiographically determined lead position, episodes of pacing failure in the preceding 6 h, and pacing thresholds were recorded every 6 h. Pacing failure was defined as a period of loss of capture longer than 20 s.ResultsPacing leads were placed with both guidance methods and maintained for 24 h with no complications. Two horses with leads angled caudally in the right ventricular apex had no pacing failure, the remaining 4 horses had varying degrees of loss of capture. Leads located in the right ventricular apex had longer time to pacing failure and lower capture thresholds P < 0.05.Conclusions and Clinical ImportanceMedium‐term TV‐TP is feasible and has potential for stabilization of horses with symptomatic bradyarrhythmias. Lead position in the right ventricular apex appears optimal. Continuous ECG monitoring is recommended to detect pacing failure.

“…The specificity of the surgical operation often entails a series of complications with TTCP, which can be categorized into two main groups: venous access-related complications or pacemaker catheter-related complications. Ultrasound-guided venous access has been shown to be safe, whereas pacemaker lead-related complications are frequently seen in clinical practice [ 6 ]. The standard TTCP lead has no fixed mechanism, which has a blunt, smooth, stiff tip that is electrically stimulated by direct contact with the myocardium through the negative pole of the lead.…”

Compared with traditional leads, carbon fiber composite leads have a series of advantages such as lightweight, soft texture, and high conductivity. In this experiment, we attempted to improve the existing carbon-fiber-based TTCP metal leads by using carbon-fiber-graphene-woven leads or conductive cloth, so as to solve a series of defects of TTCP metal leads commonly used in the clinical temporary cardiac pacemaker. We performed a series of measurements, including resistance comparisons and stability checks on the finished product characteristics. The results showed that the resistivity of the whole lead did not change significantly after modification, and the carbon fiber bundle was stable and easily deformed under lower stress to reduce the damage to the myocardium, which had excellent clinical application value.
