Heart rate

Heart rate is the frequency of the heartbeat measured by the number of contractions of the heart per minute (beats per minute, or bpm). The heart rate varies according to the body's physical needs, including the need to absorb oxygen and excrete carbon dioxide. It is also modulated by numerous factors, including (but not limited to) genetics, physical fitness, stress or psychological status, diet, drugs, hormonal status, environment, and disease/illness, as well as the interaction between these factors. It is usually equal or close to the pulse rate measured at any peripheral point. The American Heart Association states the normal resting adult human heart rate is 60–100 bpm. An ultra-trained athlete would have a resting heart rate of 37–38 bpm. Tachycardia is a high heart rate, defined as above 100 bpm at rest. Bradycardia is a low heart rate, defined as below 60 bpm at rest. When a human sleeps, a heartbeat with rates around 40–50 bpm is common and considered normal. When the heart is not beating in a regular pattern, this is referred to as an arrhythmia. Abnormalities of heart rate sometimes indicate disease.

• What Your Resting Heart Rate Says About Heart Health - Cedars-Sinai

  According to the American Heart Association (AHA), a normal resting heart rate—the number of times the heart beats per minute when the body is at rest—is 60 to 100 beats per minute for most adults. Ebinger told Fortune cardiovascular exertion lowers a person’s resting heart rate.

• Target Heart Rates Chart | American Heart Association

  For most adults, a resting heart rate between 60 and 100 beats per minute is normal. However, the rate can be affected by factors such as stress, anxiety, hormones, medication and how physically active you are. An athlete or more active person may have a resting heart rate as low as 40 beats per minute. Now that’s chill! [...] Your resting heart rate is the number of times your heart beats per minute when you’re at rest. A good time to check it is in the morning after you’ve had a good night’s sleep, before you get out of bed or grab that first cup of coffee. ## Is resting heart rate different by age? [...] When it comes to resting heart rate, lower is better. It usually means your heart muscle is in better condition and doesn’t have to work as hard to keep a steady beat. Studies have found that a higher resting heart rate is linked with lower physical fitness, higher blood pressure and higher body weight. ## Know Your Numbers: Maximum and Target Heart Rate by Age This table shows target heart rate zones for different ages. Your maximum heart rate is about 220 minus your age.

• How to lower your resting heart rate - Harvard Health

  The usual range for resting heart rate is anywhere between 60 and 90 beats per minute. Above 90 is considered high. An increase in your resting heart rate over time may be a signal of heart trouble ahead. ## What influences your resting heart rate? [...] Compared to people whose resting heart rates were under 70 beats per minute at the study's start and its end, those whose resting heart rate rose from under 70 to more than 85 were 90% more likely to have died during the course of the study. The increase in risk was slightly less for those with resting heart rates of 70 to 85 at the study's start, and who had a greater than 85 at the study's end. [...] In another study of over 129,000 postmenopausal women, researchers examined the relationship between resting heart rate and heart attacks and strokes. The study found that women with the highest resting heart rates (more than 76 beats per minute) were 26% more likely to have a heart attack or die from one than those with the lowest resting heart rates (62 beats per minute or less). ## How to measure your resting heart rate

• Exercise intensity: How to measure it - Mayo Clinic

  Multiply your age by 0.7 and subtract the total from 208 to get your maximum heart rate. Calculate your resting heart rate by counting how many times your heart beats each minute when you are at rest, such as first thing in the morning. It's usually somewhere between 60 and 100 beats per minute for the average adult. Calculate your heart rate reserve (HRR) by subtracting your resting heart rate from your maximum heart rate. [...] Now multiply 96.5 by 0.85 (85%) to get 82, then add your resting heart rate of 80 to get 162.03. This is your target heart rate at 85% intensity. Your target heart rate zone for vigorous exercise is 148 to 162 beats per minute, rounded to whole numbers. [...] First, multiply 45 by 0.7 and subtract the total from 208 to get your maximum heart rate. The maximum heart rate is 176.5. Next, check your resting heart rate first thing in the morning. Say it's 80 beats per minute. Calculate your HRR by subtracting 80 from 176.5. Your HRR is 96.5. Multiply 96.5 by 0.7 (70%) to get 67.5, then add your resting heart rate of 80 to get 147.5. This is your target heart rate at 70% intensity.

• Want to check your heart rate? Here's how - Harvard Health

  A normal heart rate for adults is typically 60 to 100 beats per minute. A heart rate that is slower than 60 beats per minute is considered bradycardia ("slow heart") and a rate that is faster than 100 beats per minutes is termed tachycardia ("fast heart"). There are some experts who believe that an ideal resting heart rate is closer to 50 to 70 beats per minute. Regardless of what is considered normal, it's important to recognize that a healthy heart rate will vary depending on the situation. [...] Measuring your heart rate is any easy way to gauge your health, as it provides a real-time snapshot of your heart muscle function. For most adults, a normal resting heart rate — the number of heartbeats per minute while at rest — ranges from 60 to 100 beats per minute. A normal heart rate can vary from person to person. However, an unusually high or low resting heart rate can be a sign of trouble. ## What is a normal heart rate? [...] At the wrist, lightly press the index and middle fingers of one hand on the opposite wrist, just below the base of the thumb. At the neck, lightly press the side of the neck, just below your jawbone. Count the number of beats in 15 seconds, and multiply by four. That's your heart rate. To get the most accurate reading, you may want to repeat a few times and use the average of the three values. For a resting heart rate measurement, you should also follow these steps:
