what happens if your heart rate goes below 50?

Bradycardia is a medical term for a slow heart rate. Most adult hearts beat between 50 and 100 times per minute at rest. If you have bradycardia, your resting heart rate is slower than usual—beating fewer than 50 times per minute. Bradycardia can be harmless, but in some cases it can be life-threatening.

It's good to remember that everyone's max heart rate does drop as they age—but again, that doesn't mean you're losing fitness. Regular training and good nutrition will affect performance more than the fact that your max heart rate is now slightly lower than it was three years ago.

If you have bradycardia, you'll have a sustained heart rate below 60 even when you're awake and active. A normal range is from 60 to 100 beats-per-minute while awake. The heart rate can also slow down normally while we are asleep to 40 to 60 beats a minute.

Your heart rate may fall below 60 BPM during deep sleep. And physically active adults (and athletes) often have a resting heart rate slower than 60 BPM.

The normal resting heart rate for adults over the age of 10 years, including older adults, is between 60 and 100 beats per minute (bpm). Highly trained athletes may have a resting heart rate below 60 bpm, sometimes reaching 40 bpm. The resting heart rate can vary within this normal range.

While it's true that some areas of cardiac muscle will start to die during a heart attack because of a lack of blood, a person's pulse may become slower (bradycardic) or faster (tachycardic), depending on the type of heart attack they're experiencing (a normal heart rate is between 60 and 100 beats per minute).

Heart rate is a good measure of how far a person is pushing themselves during exercise. A low heart rate during exercise may mean that a person could increase the intensity of that activity, while a heart rate that is too high can be dangerous.

Your heart rate drops most sharply in the first minute after you stop exercising; it should then fall about 20 beats a minute—a drop of less than 12 beats a minute is considered abnormal.

Normally, your heart beats between 60 and 100 times a minute. Eating specific foods or drinking certain beverages can raise your heart rate to above 100, creating a feeling that your heart is fluttering, racing or skipping a beat. If it happens occasionally, it's likely nothing to worry about.

Your resting heart rate will become lower as your fitness level increases. Vigorous aerobic exercise, such as running or cycling, has the most effect on lowering your resting heart rate. Moderate-intensity exercise such as brisk walking has less effect.

The normal resting heart rate for adults over the age of 10 years, including older adults, is between 60 and 100 beats per minute (bpm). Highly trained athletes may have a resting heart rate below 60 bpm, sometimes reaching 40 bpm.

Target heart rate is generally expressed as a percentage (usually between 50 percent and 85 percent) of your maximum safe heart rate. The maximum rate is based on your age, as subtracted from 220. So for a 50-year-old, maximum heart rate is 220 minus 50, or 170 beats per minute.

At a 50 percent exertion level, your target would be 50 percent of that maximum, or 85 beats per minute. At an 85 percent level of exertion, your target would be 145 beats per minute. Therefore, the target heart rate that a 50-year-old would want to aim for during exercise is 85 to 145 beats per minute.

When Your Heart Rate Slows But for others, it could be a sign that your brain and other organs aren't getting enough oxygen to function like they should. If that's the case, you may feel faint, dizzy, weak, or short of breath. You might also have chest pains, memory problems, or tire easily.

For children ages 6 to 15, the normal resting heart rate is between 70 and 100 bpm, according to the AHA. But a heart rate lower than 60 doesn't necessarily mean you have a medical problem. Active people often have lower heart rates because their heart muscles don't need to work as hard to maintain a steady beat.

Too many signals lead to a rapid heart rate. It most often ranges between 100 to 130 beats per minute or more in adults. The rapid heart rate causes the heart to work too hard and not move blood efficiently. If the heartbeat is very fast, there is less time for the heart chamber to fill with blood between beats.

Take your heart rate 1–3 minutes following an intense effort. The healthy and fit heart sees a faster decline in beats per minute. A decrease between 15–25 heart beats per minute is the normal range.
