What is indicated by the abbreviation 'HR'?

The abbreviation 'HR' commonly stands for Heart Rate in medical terminology. Heart Rate is a critical vital sign that measures the number of heartbeats per minute and is vital for assessing a patient's cardiovascular health and overall physiological state. It provides insights into the heart's efficiency, how well it is functioning, and can indicate various health conditions. Understanding and monitoring heart rate is essential for medical professionals as it can help in diagnosing issues such as tachycardia (fast heart rate) or bradycardia (slow heart rate), both of which can have significant implications for patient care.
