pulssimittausta

Pulssimittaus, often referred to as heart rate monitoring, is the process of measuring the number of times the heart beats per minute. This vital sign provides crucial information about an individual's cardiovascular health and overall physiological state. The pulse is typically felt at various points in the body where arteries are close to the skin, such as the wrist (radial artery) or neck (carotid artery). Manually, this is done by placing the index and middle fingers on the artery and counting the beats for a set period, usually 60 seconds, or for 30 seconds and multiplying by two.

Modern technology offers several methods for more continuous or precise pulssimittaus. Electronic devices like heart rate monitors, commonly found in fitness trackers, smartwatches, and chest straps, utilize sensors to detect changes in blood flow or electrical activity of the heart. Photoplethysmography (PPG) is a common optical technique used in wearables, where light is shone onto the skin, and the absorption or reflection of this light by blood is measured. Electrocardiograms (ECG or EKG) provide a more detailed electrical picture of the heart's rhythm and can also be used to determine heart rate.

Normal resting heart rate for adults typically ranges from 60 to 100 beats per minute. Athletes often have lower resting heart rates due to improved cardiovascular efficiency. Deviations from this range, such as a consistently high rate (tachycardia) or a low rate (bradycardia), can indicate underlying medical conditions and warrant further investigation by a healthcare professional. Pulssimittaus is a fundamental tool in medical diagnostics, sports performance monitoring, and general wellness tracking.
