upBeat® Biosensors are designed for continuous 24x7 monitoring of persons wherever they are at home, office, hospital, etc i.e. both inpatient and outpatient. upBeat® is undergoing rigorous pre-clinical testing to evaluate it's performance and improve it based on the feedback. This article details one such pre-clinical study for outpatient ambulatory monitoring. One case of a 71 year old female who had irregularly regular rhtyhm is detailed below.
Monitra's upBeat® Biosensors
upBeat® is a wearable medical grade biosensing skin patch that continuously 24x7 captures electrocardiogram (ECG) and tracks posture as well as activities in real-time. This physiological data is transmitted continuously to the phone and the information is relayed to our cloud platform, upBeat®.AI.
What is a irregularly irregular rhythm?
An irregularly irregular rhythm has no pattern at all. All of the intervals are haphazard and do not repeat, with an occasional, accidental exception. Only three supraventricular rhythms are irregularly irregular:
Sinus arrhythmia (one P wave morphology and stable PR interval)
Multifocal atrial rhythm (wandering atrial pacemaker) with a rate < 100, and multifocal atrial tachycardia (rate > 100) in which there are at least three different P wave morphologies and PR intervals without a dominant P wave morphology
Atrial fibrillation in which no organized P wave is identified
Heart Rate Plot during the session
Instantaneous Heart Rate versus Time plots were created for each subject where each activity was noted. You will notice that the instantaneous heart rate is scattered due to the irregularly regular rhythm.
Sitting
The heart rate is about 125 bpm during a run of 5 beats of non-sustained PSVT.
The heart rate is about 70 bpm.
Lying Down
The heart rate is about 60 bpm. Notice the constantly changing intervals between beats.
Deep Breathing
The heart rate is about 60 bpm. Notice the constantly changing intervals between beats.
The heart rate is about 70 bpm. Notice the constantly changing intervals between beats.
Walking
The heart rate is about 90 bpm. There is some amount of baseline wander. The intervals between beats change here too.
The heart rate is about 90 bpm. The intervals between beats change here too. The baseline is clean here.
Climbing up & down stairs
The heart rate is about 100 bpm. There is muscle tremor around a few beats. The intervals between beats change.
The heart rate is about 90 bpm. The intervals between beats change. The baseline is clean.
The heart rate is about 90 bpm. The intervals between beats change. The baseline is clean.
