hjartslagshraða

Hjartslagshraða, also known as heart rate, is the number of heartbeats per minute. It is an essential vital sign that reflects the heart's ability to pump blood throughout the body. The normal resting heart rate for adults typically ranges from 60 to 100 beats per minute, although this can vary based on factors such as age, fitness level, and overall health.

Heart rate can be influenced by various factors, including physical activity, emotional state, and underlying medical conditions. During physical exertion, the heart rate increases to meet the body's demand for oxygen-rich blood. Conversely, during periods of rest or sleep, the heart rate tends to slow down. Emotional stress or excitement can also cause the heart rate to accelerate temporarily.

Monitoring heart rate is crucial for diagnosing and managing various cardiovascular conditions, such as arrhythmias, heart failure, and hypertension. In clinical settings, heart rate is often measured using an electrocardiogram (ECG) or a pulse oximeter. In everyday life, it can be estimated by feeling the pulse at the neck, wrist, or groin.

Abnormal heart rates, either too fast (tachycardia) or too slow (bradycardia), can indicate underlying health issues and may require medical attention. Regular monitoring and understanding of heart rate patterns can contribute to maintaining overall cardiovascular health and well-being.
