VitalRhythm

VitalRhythm is a cloud-based software designed for continuous, automatic analysis of cardiac arrhythmias in adults for non-urgent clinical decision-making. It processes ECG and RR-interval data from the VitalPatch biosensor, with its substantial equivalence affirmed through rigorous non-clinical testing demonstrating high performance in arrhythmia detection.

VitalConnect, Inc. has received clearance for its VitalRhythm software, a cloud-based application designed for the continuous and automatic analysis of cardiac arrhythmias. This system is intended for patients aged 18 and older, supporting outpatient cardiac telemetry and monitoring in non-critical healthcare environments for non-urgent clinical decision-making. VitalRhythm processes ECG and RR-interval data obtained from the VitalPatch biosensor, with its analysis results displayed in the VistaCenter web application for review and confirmation by qualified healthcare professionals or cardiac technicians. The system's output serves as advisory information and is not intended for use in life-supporting systems or as the sole basis for diagnosis. The determination of substantial equivalence was supported by extensive non-clinical testing involving a large, independent dataset of de-identified ECG and RR-interval data from over 3,300 patients across several U.S. clinical sites. The VitalRhythm algorithm demonstrated high performance in detecting various cardiac rhythms, including atrial fibrillation/flutter, AV block, and ventricular tachycardia. The testing results, which included sensitivity, specificity, positive predictive value, negative predictive value, and accuracy, met the predefined acceptance criteria of 95% or greater for non-sinus rhythms and 90% or greater for sinus rhythms. These performance data affirm that the device is as safe and effective as comparable products for arrhythmia detection.

• Q1. What specific types of "non-critical healthcare environments" and "non-urgent clinical decision-making" is VitalRhythm best suited for, and are there any environments where its use is contraindicated?; How does the VitalRhythm algorithm differentiate between various cardiac rhythms, and what are its limitations in detecting less common or complex arrhythmias?; Given that the system's output is advisory, what is the required level of human oversight and expertise for interpreting and acting upon the results displayed in VistaCenter?; Could the independent dataset used for non-clinical testing be further characterized to understand its diversity in patient demographics, comorbidity, and arrhythmia presentation, and how might this impact generalizability?; What is the long-term plan for post-market surveillance and continuous improvement of the VitalRhythm algorithm's performance, especially for rare or emergent cardiac events?
