Real-time Heart Health Monitoring for Firefighters

The National Institute of Standards and Technology (NIST) is developing a model for real-time heart health monitoring in firefighters.

Why?

Firefighters work in strenuous environments, carrying heavy objects, climbing stairs and enduring extreme temperatures with a limited ability to cool off. These factors make firefighters a high risk for cardiac conditions and fatal cardiac events.

According to the National Fire Protection Association’s annual report:

  • Cardiac-related fatalities usually account for the largest share of on-duty firefighter deaths each year.
  • In 2022, about one-third of the 96 firefighters who died in the line of duty succumbed to a sudden cardiac event or a cardiac-related condition.

How?

NIST is using machine learning, a type of artificial intelligence, for their Heart Health Monitoring (H2M) model.

H2M was trained on actual electrocardiogram (EKG) data from 112 firefighters who were monitored throughout their entire 24-hour shift. When tested with approximately 6,000 abnormal EKG samples it had not previously seen, H2M identified them correctly with about 97% accuracy.

The goal

NIST hopes the monitoring technology will eventually be incorporated into a portable heart monitor that will accurately identify abnormal cardiac rhythms in firefighters so they can seek medical attention before it is too late.
