Calculating Average Heart Rate

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.
