The physIQ Heart Rhythm and Respiration Module (Version 2.0) is intended for use by a physician or other qualified medical professionals for the calculation of heart rate and heart rate variability, the detection of atrial fibrillation and determination of respiration rate using ambulatory ECG and triaxial accelerometer data. The physIQ Heart Rhythm and Respiration Module supports receiving and analyzing single-lead ECG signals recorded in a compatible format from FDA-cleared ECG biosensor devices using “wet” electrode technology and triaxial accelerometers when assessment of rhythm and respiration rate is desired. The physIQ Heart Rhythm and Respiration Module is for use in adult patients in subacute clinical and nonclinical settings for remote patient monitoring. The physIQ Heart Rhythm and Respiration Module is not for use in patients requiring life-supporting or life-sustaining systems or as ECG or respiration alarm devices.
Indications for use as stated in the FDA summary.
