ST segment depression & T-wave inversion post climbing stairs - 79 year old male

December 8, 2018

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 79 year old male where ST segment depression & T-wave inversion post climbing stairs were observed is detailed below.

 

 

Heart Rate Plot during the session

 

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

 

 

Sitting

 

The heart rate is about 70 bpm.

 

Lying Down

 

The heart rate is about 60 bpm.

 

Walking

 

The heart rate is about 90 bpm.

 

Climbing up & down stairs

 

The heart rate is about 100 bpm.

 

Walking after climbing up & down stairs

 

The subject experienced exhaustion and hence stopped climbing up & down stairs and started walking thereafter. Heart rate is about about 110 bpm. Notice ST segment depression & T-wave inversion.

 

Sitting

 

The heart rate falls to about 70bpm after sitting and the ECG reverts back to the baseline without ST segment depression & T-wave inversion.
