“…The history of clinical electrophysiology is long; however, the identification and treatment of cardiac arrhythmias first occurred in this century. 3 , 4 While ancient Chinese and Arabic cultures have long used pulse measurements as diagnostic tools, it was not until the 19th century that the field of physiology truly blossomed, propelled by a slew of innovative instruments that revolutionized research. 3 Willem Einthoven, embarked on this journey with the Lippamann capillary electrometer in 1895.…”

“…1 Since that time, it has been understood that the diagnosis and ablation of cardiac arrhythmias is facilitated by accurate and precise visualisation of those EGMs and the ability to assess the relative timing and direction of electrical propagation within the heart. 2 The information contained in intracardiac EGMs is highly dependent on the recording technique and equipment. Unipolar EGMs can provide valuable information regarding the local depolarisation sequence and the direction of electrical propagation that cannot be ascertained from individual bipolar recordings.…”

Aims: The interpretation of intracardiac electrograms recorded from conventional electrophysiology recording systems is frequently impacted by powerline (50/60 Hz) noise and distortion due to notch filtering. This study compares unipolar electrograms recorded simultaneously from a conventional electrophysiology recording system and one of two 3D mapping systems (control system) with those from a novel system (ECGenius, CathVision ApS) designed to reduce noise without the need for conventional filtering. Methods: Unipolar electrograms were recorded simultaneously from nine consecutive patients undergoing catheter ablation for AF (five patients), atrioventricular nodal re-entrant tachycardia (three patients), or ventricular tachycardia (one patient) over the course of 1 week in 2020. Results: The noise spectral power of the novel system (49–51 Hz) was 6.1 ± 6.2 times lower than that of the control system. Saturation artefact following pacing (duration 97 ± 85 ms) occurred in eight control recordings and no novel system recordings (p<0.001). High frequency, low amplitude signals and fractionated electrograms apparent on unfiltered novel system unipolar recordings were not present on control recordings. Control system notch filtering obscured His bundle electrograms observable without such filtering using the novel system and induced electrogram distortion that was not present on novel system recordings. Signal saturation occurred in five of seven control system recordings but none of the novel system recordings. Conclusion: In this study, novel system recordings exhibited less noise and fewer signal artefacts than the conventional control system and did not require notch filtering that distorted electrograms on control recordings. The novel recording system provided superior electrogram data not apparent with conventional systems.
