What is the term for the number of heartbeats per minute?

• A. Cardiac Output
• B. Pulse
• C. Heart Rate
• D. Blood Flow

Answer: (B)

The correct term for the number of heartbeats per minute is heart rate. Heart rate is a vital sign that indicates how many times the heart beats within a minute, reflecting the heart's rhythm and efficiency in pumping blood throughout the body. It is commonly measured while at rest and can vary based on factors such as age, physical condition, and activity level. While pulse is often associated with heart rate, it specifically refers to the tangible beat felt in the arteries as blood is pumped through them. Although pulse can provide an indication of heart rate, the two terms are not interchangeable; pulse can be affected by other factors like vascular health and circulation efficiency. Cardiac output refers to the total volume of blood the heart pumps in one minute and is a product of heart rate and stroke volume, which is the amount of blood ejected with each heartbeat. Blood flow, on the other hand, generally describes the movement of blood within the circulatory system but does not directly indicate the number of heartbeats. Understanding the distinction between these terms helps in accurately assessing and discussing cardiovascular health and function.
