The summary describes proprietary algorithms for signal processing and display, but does not mention AI or ML. The validation focuses on the accuracy of the signal processing and the physician's ability to use the output for diagnosis, not on the performance of an AI/ML model.
No
The device is used to assist in diagnosis and compute and display electrical information for review by a physician; it does not directly treat or provide therapy.
Yes
The "Intended Use / Indications for Use" section explicitly states that "The Rhythm View Workstation is a computerized system that assists in the diagnosis of complex cardiac arrhythmias." Additionally, the "Device Description" notes that it "outputs a graphic display that assists in the diagnosis of cardiac arrhythmias" and "aids diagnosis by the physician."
No
The device description explicitly lists multiple hardware components including a Cart, Monitor/Display, Computer, RFID Reader/Writer, Keyboard, Mouse, Two Port USB Switch, and an optional Solid State Hard Drive, in addition to the software.
Based on the provided information, the Rhythm View Workstation is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Rhythm View's Function: The Rhythm View Workstation analyzes electrical signals collected directly from within the heart during an electrophysiological study. It does not analyze specimens taken from the body.
- Input: The input is electrogram and electrocardiogram signals, which are electrical measurements, not biological specimens.
- Purpose: Its purpose is to assist in the diagnosis of cardiac arrhythmias by analyzing these electrical signals and displaying them visually.
Therefore, the Rhythm View Workstation falls under the category of a medical device used for diagnosis, but it is not an IVD device as it does not perform testing on in vitro specimens.

Cart
Monitor/Display
Computer
Radio-Frequency Identification (RFID) Reader/Writer
Software
Keyboard
Mouse
Two Port USB Switch
Solid State Hard Drive (optional component)
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.

Dear Dennis Pozzo:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices. good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
