1. A method for determining a heart rate, comprising:
- detecting, using at least a first sensor on a person, a heart rate of the person based on sensed electrical activity of the person;
detecting, using at least a second sensor on the person, a pulse rate of the person based on at least one sensed parameter other than the sensed electrical activity of the person;
transmitting, from the first sensor to the second sensor, the detected heart rate of the person;
comparing, at the second sensor, a frequency domain analysis of the determined heart rate and the determined pulse rate; and
generating, at the second sensor, an alert event based at least in part on a measure associated with the comparison being outside of a predetermined threshold.

Abstract
Methods, systems, and devices for determining pulseless electrical activity (PEA) are described. The method may include determining by using a first sensor on a person, a heart rate of the person based on sensed electrical activity of the person. A pulse rate of the person may be determined using a second sensor, the pulse rate of the person being based on at least one sensed parameter other than the sensed electrical activity. The method may then include determining a correlation of the determined heart rate and the determined pulse rate and then generating an alert event based at least in part on the correlation being outside of a predetermined threshold.
