Non-sustained PSVT - 95 years old male

Updated: Sep 23, 2022

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 95 year old male where an episode of non-sustained PSVT was observed 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 non-sustained PSVT?

Premature supraventricular beats may occur singly or repetitively. A sudden run of three or more such consecutive nonsinus beats constitutes an episode of paroxysmal supraventricular tachycardia (PSVT).

Episodes of PSVT may be brief and non-sustained (i.e., lasting from a few beats up to 30 sec). Sustained episodes (greater than 30 sec) may last minutes, hours, or longer.

Heart Rate Plot during the session

Instantaneous Heart Rate versus Time plots were created for each subject where each activity was noted.

Heart Rate Plot

Lying down - A run of 7 beats of non -sustained PSVT

The heart rate is about 120 bpm during non-sustained PSVT.


Sitting Down

The heart rate is about 60 bpm. Notice presence of PVC with the associated compensatory pause..

Deep Breaths

Deep Breathing - A run of 5 beats of non -sustained PSVT

The heart rate is about 120 bpm during non-sustained PSVT.



The heart rate is about 75 bpm.


Climbing up & down stairs

The heart rate is about 90 bpm. There is some amount of baseline wander.
