Final answer:
A typical slow RHR is below 60 bpm, a normal RHR is between 60-100 bpm, and a fast RHR is above 100 bpm. Rates are influenced by factors like age and fitness level, and maximum heart rates decrease as one ages.
Step-by-step explanation:
Typical heart rate (HR) ranges vary based on the condition being described. A normal resting heart rate (RHR) for healthy adults is between 60 to 100 beats per minute (bpm). A slow resting heart rate, known as bradycardia, is when the resting rate drops below 60 bpm, while a fast resting heart rate, known as tachycardia, is when the resting rate is above 100 bpm. Trained athletes often have a resting heart rate below the normal range due to their high level of cardiovascular fitness.
It's important to note that resting heart rates can be influenced by a variety of factors, including age, fitness level, and even the presence of certain health conditions. For instance, newborns can have a resting HR of around 120 bpm, which decreases into young adulthood and then gradually increases with age.
Furthermore, maximum heart rates can typically range between 200-220 bpm, but this decreases with age. For example, a 40-year-old individual would have an estimated maximum heart rate of approximately 180 bpm.
