cardiac power meter
A monitoring device that estimates cardiac work and power output based on heart rate variability and other physiological parameters.
Full Definition
A cardiac power meter is an advanced wearable technology that provides real-time estimation of cardiac mechanical work and power output during exercise. These devices utilize algorithms incorporating heart rate variability, acceleration data, and sometimes additional sensors to estimate stroke volume and cardiac output. Unlike traditional heart rate monitors, cardiac power meters attempt to quantify the actual work performed by the heart muscle itself. In sports cardiology applications, these devices help optimize training loads, monitor cardiac stress, and potentially identify early signs of overreaching or cardiac dysfunction. The technology represents an emerging field in exercise physiology monitoring, though clinical validation remains ongoing.
Usage
Usage note: Distinguish clearly from cycling power meters; specify units when reporting values.
