hartslagmeters
Hartslagmeters, often called heart-rate monitors in English, are devices that measure heart rate in beats per minute (bpm). They are used to monitor cardiovascular activity during rest or physical exertion and can transmit data to watches, smartphones, or gym equipment. Most models provide real-time readouts and store historical data for analysis.
Most hartslagmeters operate using one of two methods. Chest-worn devices use electrodes to detect the heart's
Common uses include training optimization, where heart-rate zones guide effort, recovery assessment, and general health monitoring.
Accuracy and limitations vary by device and conditions. Motion artifacts, poor sensor contact, tattoos, skin tone,
