What is a dangerous heart rate

When rapid heart rate is accompanied by chest pain, shortness of breath, or fainting, seek medical attention immediately. Causes The heart regulates its rate in response to various situations in order to provide enough blood flow to the body. Certain factors can contribute to increased heart rate, including: Arrhythmias with a rapid heart rate can be caused by any of the following: • Structural heart problems • Congenital heart problems • Ischemia of the heart, as in a • Scar from a prior heart attack • • • Lung disease like • • Thyroid problems • Certain medications • Alcohol • Drugs like cocaine Types of Rapid Heart Rate The heart has a specialized electrical conduction system that starts in a group of cells called the sinus node. It is located in the right atrium, one of the heart's upper chambers. Atrial fibrillation is serious because it increases the risk of If you have ever experienced A-fib, you may be able to lower your risk of stroke by taking anticoagulation (blood-thinning) drugs. They may be recommended even if your heart rhythm returns to normal, since the risk of stroke remains. Atrial Flutter In a cardiac emergency, attempt the following steps: • If you see someone become unresponsive, feel for a pulse. • If there is no pulse, call for help immediately and start CPR. • Send someone to find an Don't be afraid to use an AED if needed—you could save someone's life. Summary Rapid heart rate is defined as a heart rate of more than 100 beats per minute. Other sym...

What Is Heart Rate? Your heart rate is the number of beats your heart completes each minute. Heart rate is also known as pulse and is what you feel when you press your wrist or neck to check your pulse. Your heart rate changes constantly based on what you are doing. It changes with physical activity and in response to an emotional stimulus such as excitement or anxiety. Resting Heart Rate Resting heart rate (RHR) is the number of beats per minute your heart completes when you are completely at rest. It is the lowest rate your heart usually beats since you are not being active. This rate should be measured when you are resting (sitting or lying down), without any emotional stimulus or illness influencing the rate. A Target Heart Rate Target heart rate is a goal of how fast you want your heart rate to be while exercising. It helps indicate the intensity you are working. Your estimate for your target heart rate is just a guess, but it gives you an idea of how hard you work during exercise. Your target heart rate will depend on your current fitness level and age, which means it will change as your cardiovascular endurance increases or as you get older. Some fitness trackers or smartwatches automatically measure your resting heart rate and then use that information to suggest and measure the target heart rate. An advantage of using these devices to find your target heart rate is that the manufacturer can easily update them to match the current research-backed zones. Age Low Int...

Typical heartbeat In a typical heart rhythm, a tiny cluster of cells at the sinus node sends out an electrical signal. The signal then travels through the atria to the atrioventricular (AV) node and into the ventricles, causing them to contract and pump blood. A heart arrhythmia (uh-RITH-me-uh) is an irregular heartbeat. Heart rhythm problems (heart arrhythmias) occur when the electrical signals that coordinate the heart's beats don't work properly. The faulty signaling causes the heart to beat too fast (tachycardia), too slow (bradycardia) or irregularly. Heart arrhythmias may feel like a fluttering or racing heart and may be harmless. However, some heart arrhythmias may cause bothersome — sometimes even life-threatening — signs and symptoms. However, sometimes it's normal for a person to have a fast or slow heart rate. For example, the heart rate may increase with exercise or slow down during sleep. Heart arrhythmia treatment may include medications, catheter procedures, implanted devices or surgery to control or eliminate fast, slow or irregular heartbeats. A heart-healthy lifestyle can help prevent heart damage that can trigger certain heart arrhythmias. Types In general, heart arrhythmias are grouped by the speed of the heart rate. For example: • Tachycardia (tak-ih-KAHR-dee-uh) is a fast heart. The resting heart rate is greater than 100 beats a minute. • Bradycardia (brad-e-KAHR-dee-uh) is a slow heartbeat. The resting heart rate is less than 60 beats a minute. Fast ...

Heart rate is the number of times your heart beats in 1 minute. A rate that is too high or too low can affect how blood and oxygen circulate in the body. A dangerous heart rate can lead to serious health effects. A high or low heart rate may indicate a serious underlying condition. Therefore, it is important to know the signs and symptoms of an irregular or unsafe heart rate. This article discusses heart rates, what is safe and dangerous, and the symptoms of dangerous heart rates. It explains when to seek medical help and answers frequently asked questions about heart rates. However, some factors can cause expected or benign variations in heart rate temporarily. For example: • Exercise naturally increases heart rate. • Deep sleep Trusted Source PubMed Central Highly respected database from the National Institutes of Health • • Older adults Trusted Source American Heart Association Highly respected national organization • Athletes Additionally, standard or expected heart rates can vary depending on individual factors. These factors include age, activity levels, and fitness. An older, Trusted Source PubMed Central Highly respected database from the National Institutes of Health Identifying your own typical resting heart rate helps you know when it has become too high or too low. To do this, measure your pulse Target and maximum heart rates Everyone has a maximum safe heart rate that they should try not to exceed. According to the AHA, to calculate your maximum heart rate, su...

What should your heart rate be when working out, and how can you keep track of it? Our simple chart will help keep you in the target training zone, whether you want to lose weight or just maximize your workout. Find out what normal resting and maximum heart rates are for your age and how exercise intensity and other factors affect heart rate. How do I get my heart rate in the target zone? When you work out, are you doing too much or not enough? There’s a simple way to know: Your target heart rate helps you hit the bullseye so you can get max benefit from every step, swing and squat. Even if you’re not a gym rat or elite athlete, knowing your heart rate (or pulse) can help you track your health and fitness level. What is a resting heart rate? 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 java! Is resting heart rate different by age? For most of us (adults), between 60 and 100 beats per minute (bpm) is normal. 1 The rate can be affected by factors like 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! 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 maintain a stea...
