Description of intervention(s) / exposure
This is a proof-of-concept study of a wearable vital signs monitor and App. The primary objective of the trial is to test the hypothesis that the Saiiv Morphic sensors (singularly or in combination), at various anatomical locations, are able to accurately detect atrial fibrillation and measure blood pressure and vascular stiffness compared to standard measurement techniques.

Vital signs will be measured in 30 participants including 15 with atrial fibrillation and 15 with sinus rhythm. Once consented, all participants will be monitored over a 15 minute period. The study will occur in the hospital/ward setting and in ICU.

Participants will lay supine. For the duration of the study participants will be fitted with a 5 lead ECG, one morphic dot over the heart, one morphic dot on the lower sternum, a central blood pressure monitor on the finger (Finapres) and arterial line to measure blood pressure will be in situ as part of routine standard of care.

For 1 minute in a series the participant will have the following fitted to measure vital signs and sounds; a digital stethoscope, echocardiogram, Sphygmocor device (measuring arterial stiffness), morphic dot on writs, morphic dot and band on neck, morphic dot on suprasternal notch and morphic dot on temple.

Early Detection / Screening
Comparator / control treatment
Vital signs from the investigational product will be compared with gold standard vital sign monitoring equipment including radial artery cannulation (if participant is cannulated as part of routine medical management) or non-invasive continuous blood pressure monitoring, ECG, echocardiogram and digital stethoscope.

Statistical methods / analysis
As per the Clinical Trial Handbook [15] pre-market pilot studies including proof of concept studies typically recruits 10-30 participants. Consequently 30 participants will be recruited into this trial in order to obtain 15 samples of data in both AF and SR. All participants enrolled in the study will be evaluated. Statistics will be presented descriptively and using Lin's concordance correlation coefficient (CCC).

Summary
Brief summary
The purpose of this trial is to test the specificity and sensitivity of two types of sensors, used in the Saiiv device, in detecting AF when compared to ECG. Other vital signs including blood pressure (and related arterial stiffness) as well as mechanical performance of the heart will also be measured and compared with standard measurement techniques.
