Most people have experienced a racing or fast heart rate, possibly due to adrenaline, anxiety, or physical activity. But have you thought about a slow heart rate? Should you be concerned if your resting heart rate is below the normal level? Show
Slow Isn’t Always BadA slow resting heart rate is known as bradycardia, which occurs at 60 beats per minute (bpm) or less, even when active. In contrast, a normal resting heart rate will fall in a range between 60 – 100 bpm. A slow heartbeat isn't always a concern, though. A resting heart rate between 40 and 60 beats a minute during sleep is common for many people during sleep. It’s also common for trained athletes, healthy young adults, and those who work out regularly to have a low heart rate while exercising – this low heart rate associated with fitness is health and normal. Also, older adults frequently have slower heart rates as their normal rhythms tend to slow down over time. Yet, there are times when a slow heart rate can indicate an underlying health condition. If you have a slow resting heart rate along with the following symptoms it can be cause for concern:
Fortunately, bradycardia usually isn’t an emergency and typically gives doctors some time to choose the right treatment. Causes of Low Heart Rate ProblemsThe most common cause of a low heart rate is a malfunction in the heart’s sinus node, its natural pacemaker. This area sends our electrical signals telling the top and bottom heart chambers the timing of when to pump blood through the body. Other causes of low heart rate include an atrioventricular block, age, and certain conditions such as inflammation of the heart muscle, low thyroid function, electrolyte imbalance, obstructive sleep apnea, or heart attack due to coronary artery disease. Is Treatment Required?A low resting heart rate without symptoms isn’t usually a cause of concern, but it’s good to know what problems might occur if this does become a problem. A low resting heart rate in the 30s, for example, means the required oxygen isn’t getting to the brain. This can make shortness of breath, fainting, and lightheadedness a possibility. For those with symptoms, visit your physician to explore the situation more in-depth. Sometimes an EKG is used to measure the electrical signals in your heart. If needed, a pacemaker can be implanted to speed up your heart rate. How to Reduce Your Risk of Developing Heart DiseaseEven though bradycardia may not be prevented, you can reduce your risk of heart disease through regular exercise, eating heathy foods, keeping blood pressure and cholesterol in check, managing stress, and monitoring and treating existing heart disease. I cannot overemphasize the importance of having regular physical exams and notifying your doctor of symptoms you are experiencing. This may be the only way to catch a problem that usually does not have symptoms early on. A normal pulse rate for adults is between 60 and 100 beats per minute. While pulse rates, also known as heart rates, can vary, certain rates may signal a serious condition. Your heart rate is the number of times your heart beats in a minute. Your heart rate doesn’t always stay the same. In fact, you may be familiar that it can sometimes change in response to things like your activity level and emotional state. Heart rate is often measured when you’re at rest and relaxed. This is called your resting heart rate. For adults, a normal resting heart rate is between 60 and 100 beats per minute (bpm). The normal resting heart rate for children can be higher than that of adults, depending on their age. While heart rates can vary from person to person, certain heart rates can be considered dangerous. Read on to learn more. While age and activity level can affect your heart rate, as we mentioned above, there are a few “normal” parameters. Your resting heart rate is when your heart pumps the minimal amount of blood that your body needs because you’re at rest. Resting heart rates can vary by individual. Additionally, factors like age, activity level, and certain medications can also impact your resting heart rate. Normal resting heart rate for adultsAccording to the American Heart Association (AHA), a normal resting heart rate is between 60 and 100 bpm. But some people may have a resting heart rate that’s lower than 60 bpm and is still considered normal. For example, athletes may find their heart rates are lower, sometimes as low as 40 bpm. Additionally, people taking certain medications, like beta-blockers, may also have a lower resting heart rate. We’ll explore more factors that can influence resting heart rate later on. The table below shows the average normal resting heart rate for adults based on age. Normal resting heart rate for kidsAs children grow, their normal resting heart rate changes. The table below shows pediatric resting heart rates, both when children are awake and asleep, according to the Department of Health and Human Services. Factors that can affect resting heart rateIn addition to age, a few other factors can affect your resting heart rate.
Your maximum heart rate is a calculation that helps you figure out what your ideal target heart rate is during exercise. You can estimate your maximum age-related heart rate by subtracting your age from 220. For example, for a 35-year-old person, the estimated maximum age-related heart rate would be calculated as 220 – 35 years = 185 bpm. This maximum heart rate calculation helps you see if you’re exercising too hard or not putting in enough energy. Your target heart rate uses this calculation to reflect the ideal bpm you need for a great workout. What is a target heart rate?According to the AHA , your target heart rate during moderate-intensity activities is about 50 to 70 percent of your maximum heart rate. Vigorous physical activity should result in about 70 to 85 percent of your maximum. So for 35-year-olds, a goal target heart rate is between 93 and 157 bpm (50 to 85 percent of their maximum). The table below shows the target heart rate range and average maximum heart rate for different ages, based on information from the AHA. There may be times when you experience a heart rate that’s faster or slower than what’s normal for you. Not every single instance of this type of bpm imbalance is considered “dangerous,” especially when a doctor is monitoring it. High heart rateWhen your heart rate is too fast, it’s called tachycardia. For adults, a fast heart rate is defined as above 100 bpm. But what’s considered too fast may also depend on your age and overall health. There are several types of tachycardia, like:
Their classification is based on their cause and the part of the heart they affect. Experiencing tachycardia may be temporary. Some possible causes of tachycardia can include:
Slow heart rateWhen your heart rate is too slow, it’s referred to as bradycardia. Bradycardia is typically defined as a heart rate less than 60 bpm. For athletes and people that exercise regularly, a heart rate of under 60 beats per minute is normal and even healthy. Some possible causes of bradycardia include:
Borderline or occasional bradycardia may not need treatment. But prolonged bradycardia, or bradycardia that’s not treated, can become more serious. Certain underlying conditions are typically the true decider of what a “dangerous” heart rate is. If you’re already living with heart disease, heart failure, or a history of heart disease and notice a fluctuation in your heart rate, you should go to the doctor as soon as you can, as it could be a sign of a serious complication. When is it an emergency?Medical emergency While there are a wide variety of wearable devices that can help you check your own heart rate, you can also do it manually. The AHA has a simple method:
Note: Don’t rely on this method if you’re feeling like your heart is beating too fast or too slow and you’re uncomfortable. The best solution for this scenario is to get a doctor’s advice. Tachycardia, which is when your heart rate is faster than it should be, can be caused by underlying health conditions like:
Taking illegal drugs (like stimulants like cocaine or methamphetamines) or misusing prescription medications or non-prescription products (like diet supplements) may also cause your heart to beat too fast. Other, less serious reasons for a fast heart rate include:
You should visit your doctor if your heart rate is consistently above 100 beats per minute or below 60 beats per minute (and you’re not an athlete), or you’re also experiencing:
Your doctor may use a variety of diagnostic tools to help diagnose your condition, including:
Once a diagnosis is made, your doctor will work with you to develop a plan to treat and manage your condition. You should always aim to take good care of your heart. This includes exercising regularly, eating heart-healthy foods, minimizing alcohol, and maintaining a moderate weight. Additionally, you should visit your doctor regularly for physicals. Not only is it good practice, but it can also help with the early detection of high cholesterol or blood pressure abnormalities. If you already have heart disease, you should carefully monitor your condition and stick to your treatment plan. Take all medications as instructed by your doctor. Be sure to promptly report any new or worsening symptoms. Other heart health tips include:
Resting heart rate can vary from person to person and can be influenced by a variety of factors. A normal resting heart rate for an adult (who isn’t an athlete) is between 60 and 100 beats per minute. The normal heart rate for children changes as they age. Both tachycardia (fast heart rate) and bradycardia (low heart rate) are typically indicators of other health conditions. If left untreated, they can lead to potentially serious health complications. If you’re experiencing a heart rate that’s consistently too high or too low, you should make an appointment with a doctor, as there are a variety of reasons this could be occurring. While not all of these reasons are dangerous, some could be signs of heart trouble. Read this article in Spanish. What is a dangerously low heart rate?What is bradycardia? Bradycardia is a condition where your heart beats fewer than 60 times per minute, which is unusually slow. This condition may be dangerous if it keeps your heart from pumping enough blood to meet your body's needs.
What is the lowest pulse rate you can have?In general, for adults, a resting heart rate of fewer than 60 beats per minute (BPM) qualifies as bradycardia. But there are exceptions. 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.
When should I go to the ER for low heart rate?Adults and children who have a low pulse and experience symptoms such as chest pain, fainting, or exercise intolerance should also go to the hospital. A person should contact a doctor about bradycardia when they: experience an unexplained change in heart rate that lasts for several days.
What is the safest lowest pulse rate?While a heart rate is considered normal if the rate is between 60 and 100 beats per minute, most healthy relaxed adults have a resting heart rate below 90 beats per minute.
