Calculating Average Heart Rate

Study Notes

Cardiovascular Tasks

Electrocardiograms (ECGs) and photoplethysmograms (PPGs) are used to understand the heart's functioning and detect heart beats.
Interbeat intervals (IBIs) can be computed from these waveforms.
Five cardiovascular tasks are involved:
- Computing average heart rate (HR) from instantaneous HR measurements.
- Calculating average heart rate from interbeat intervals.
- Classifying atrial fibrillation from IBIs.
- Classifying sinus bradycardia from IBIs.
- Classifying sinus tachycardia from IBIs.

Datasets

The MIT-BIH Atrial Fibrillation Database and the MIMIC-III dataset are used for cardiovascular tasks.
These datasets are collected from IRB-approved studies with informed consent from all research subjects.
25 samples of each class are used for training and 100 samples for testing.

Experiments

Results of 3, 10, and 25-shot experiments are shown for nine health tasks.
Prompts include IBI sequences (in milliseconds) and the model is asked to provide:
- Instantaneous heart rate (A).
- Average heart rate in beats per minute (B).
- Presence or absence of atrial fibrillation (D).
- Presence or absence of slowed heart rate/bradycardia (E).
- Presence or absence of elevated heart rate/tachycardia (F).

Metabolic Tasks

Assessing energy expenditure is essential for health and wellness monitoring.
Estimating calories burned based on physical activity is a complex calculation that requires multiple factors.

Description

Given a sequence of heart rates, calculate the average heart rate. This quiz assesses your understanding of instantaneous heart rate and average heart rate. Test your skills and knowledge in this topic.
