HFVI Monitor is intended for use in a medical environment and under the direct supervision of a licensed healthcare practitioner or by personnel specifically trained for its use. The system is intended for use on adult and pediatric patients, in a facility providing patient care by monitoring heart rate variability.The High Frequency Variability Index (HFVI) is a complex monitoring technology intended for use as an adjunct to clinical judgment. Clinical judgment should always be used when interpreting the HFVI in conjunction with other available clinical signs. As with any monitored parameter, artifacts and poor signal quality may lead to inappropriate HFVI values. Potential artifacts may be caused by muscle activity or rigidity, patient motion, improper sensor placement or electrical interference.
A device intended to be used by a healthcare professional in a clinical setting to acquire and process the electrical activity of the heart for digital display in the form of a graph, to assist a physician in assessing electrical cardiac physiology [electrocardiography (ECG)]. It is designed for recording the electrical signal from only one configuration of electrodes (ECG-leads) at a time (single-channel). It will either include an integrated display or be designed to transmit ECG data to an off-the-shelf device for display; ECG electrodes may be included. Data interpretation and/or data telemetry features might also be included.
