Intended Use

The RhythmView Workstation is a computerized system that assists in the diagnosis of complex cardiac arrhythmias. The RhythmView Workstation is used to analyze electrogram and electrocardiogram signals and display them in a visual format.

Device Story

RhythmView Workstation is a computerized diagnostic system used in electrophysiology labs by physicians to analyze cardiac arrhythmias. It accepts electrical signals from multi-polar electrophysiology catheters as input. Proprietary algorithms process these signals to compute spatial organization of electrical activity, identifying rotors or focal beat sources. The system outputs interactive, visual graphic displays—including activation maps, depol/repol contours, and rotational activity profiles—to assist in diagnosing heart rhythm disorders. New features include a 'Stability Map' for composite RAP profile display over an entire epoch and an 'epoch timeline' for segment selection. The workstation aids clinical decision-making by providing visual representations of complex electrical patterns, potentially improving diagnostic accuracy for arrhythmias like AF, VT, and VF.

Clinical Evidence

Bench testing only. Validation included software and user verification protocols. Key activities: validation of Stability Map and default Stability Filter using clinical data sets; verification of Stability Map compilation accuracy; physician validation confirming consistency of activation maps with/without RAP; and simulated user testing for UI updates.

Technological Characteristics

Workstation includes cart, monitor, keyboard, mouse, computer, two-port USB switch, and RFID reader/writer. Powered by 12V DC Lithium Iron Phosphate battery (40 Ah). Software written in C++. Complies with ISO 14971:2012, IEC 60601-1 (3rd Ed), and IEC 60601-1-2:2007. Features include signal processing, post-processing display, and proprietary RAP (Rotational Activity Profile) algorithms.

Indications for Use

Indicated for patients undergoing electrophysiological studies for the diagnosis of complex cardiac arrhythmias, including focal AT, AFL, other SVT, AF, VT, and VF.

Regulatory Classification

Identification

RhythmView takes electrical signals collected from multi-polar electrophysiology catheters and outputs a graphic display that assists in the diagnosis of cardiac arrhythmias.

The RhythmView computes and displays electrical rotors or focal beat sources that may sustain human heart rhythm disorders including focal AT, AFL, other SVT, AF, VT and VF in a given patient. The product takes as input electrical signals recorded during the heart rhythm disorder under consideration, typically from multiple specified locations within the heart during an electrophysiological study. The RhythmView then uses proprietary patented algorithms and methods to compute spatial organization during the heart rhythm disorder. These computed elements are displayed graphically in interactive form for review to aid diagnosis by the physician during an electrophysiology study.
