What this trial studies

This is a pre-market, non-pivotal study of a portable Smart ECG system composed of a 12-lead display, radiotransparent ECG cable, and automatic interval-measurement software used during pacing lead placement in the interventricular septum. The software automatically calculates Left Ventricular Activation Time (LVAT) and the V6–V1 interval and provides a visual shadow plot of the QRS to support decisions about capture. The device is Class IIa and non-implantable, and the study will compare the system's automatic measurements to usual electrophysiology monitoring during de novo implants, revisions, or upgrades including CRT and LOT-CRT. The goal is to determine whether the system reliably provides immediate ECG measurements that let physicians focus on accurate lead positioning.

Who should consider this trial

Good fit: Adults who need left bundle branch area pacing as part of a pacemaker or CRT-P/CRT-D implantation (including new implants, revisions, or upgrades) and who can give informed consent are ideal candidates.

Not a fit: Minors, incapacitated patients, those who cannot understand the study, non-menopausal women, and patients with other electrically active non-cardiac implanted devices are excluded and would not benefit from participation.

Why it matters

Potential benefit: If successful, the system could give immediate, automated ECG measurements during implantation that may speed decision-making and improve accuracy of lead placement.

How similar studies have performed: ECG criteria such as LVAT and V6–V1 interval are established in the literature for identifying left bundle branch capture, but this specific portable automatic-monitoring assistant is a novel, non-pivotal device-level evaluation.
