Szívritmusmérvel

Szívritmusmérvel, commonly translated as heart rate monitor, is a device used to measure and display a person's heart rate. These devices are utilized in various contexts, from sports and fitness to medical diagnostics. In sports, heart rate monitors help individuals optimize their training by keeping them within target heart rate zones, which can improve cardiovascular health and performance. They can also provide valuable feedback on exertion levels and recovery.

Medical applications of heart rate monitoring are extensive. Electrocardiograms (ECGs or EKGs) are sophisticated forms of heart rate measurement that record the electrical activity of the heart. Portable ECG devices can be used for continuous monitoring over extended periods, helping doctors detect arrhythmias or other cardiac irregularities. Hospital settings frequently employ cardiac monitors that display vital signs, including heart rate, in real-time for patients, especially those in critical care.

The technology behind heart rate monitors varies. Some use photoplethysmography (PPG), which detects changes in blood volume in the capillaries of the finger or wrist by shining light through the skin. Others utilize electrical sensors that pick up the electrical signals generated by the heart's contractions. The data collected by heart rate monitors can be displayed on a screen, transmitted wirelessly to a smartphone or computer, or recorded for later analysis. This information allows for better understanding of the body's response to physical activity, stress, and medical conditions.
