Is Bradycardia Dangerous
For most young people, highly trained athletes, and people who exercise regularly, a below-60 heart rate is normal and healthy. It is very possible to have a slow heart rate and experience no symptoms.
However, if you have symptoms but ignore them, it can sometimes cause more serious problems.
Consult your doctor if you are experiencing some of these symptoms and you have an associated slow heart rate:
- Lack of energy.
- Confusion/memory problems.
- Heart palpitations or flutters.
If your heart rate drops into the 30s, you might not get enough oxygen to your brain, making fainting, lightheadedness, and shortness of breath possible. Blood can also pool in your heart chambers, causing congestive heart failure.
When To See A Doctor
A person should speak to a doctor if they notice their heart rate is slow.
When a baby has a low pulse, a parent or carer should take them to the emergency room.
Adults and children who have a low pulse and experience severe symptoms, such as chest pain or fainting, should also go to the hospital.
A person should see a doctor for bradycardia when:
- they experience an unexplained change in heart rate that lasts for several days
- they have bradycardia and other heart health risk factors, such as diabetes or smoking
- they have heart disease and bradycardia
- they experience bradycardia and other symptoms, such as fainting spells
- they experience episodes of bradycardia and tachycardia
Fast Heart Rate Causes
Fast heart rate, or tachycardia, is defined as a heart beating more than 100 times per minute. Sometimes a fast heartbeat is regular, but other times the beat is erratic, which is referred to as an . A fast heartbeat can occur briefly or can continue for a longer period of time. You may not even know you have a fast heart rate unless you are examined. You may or may not have other symptoms along with a fast heart rate.
Some issues that can cause a fast heart rate include:
- Sudden fright or shock
- Use of illegal stimulant drugs, such as cocaine
Sometimes, eating certain foods or overeating can bring on a fast heart rate. This is because eating causes blood to be redirected to your digestive system, which can raise both your heart rate and blood pressure.
Certain foods also contain substances that can trigger higher heart rate in some people. Examples include sugary or high-carb foods in people with low blood sugar high-salt foods in those with or eating spicy foods that cause , which can result in a pounding heart. Usually, a fast heart rate after eating is not a cause for concern, but you should mention its occurrence to your doctor, especially if this happens repeatedly.

What Happens If I Go Over My 90% Heart Rate Goal When I Exercise
One of the reasons that experts recommend that you see your doctor before you start any exercise program is so that you can determine just how much exercise you can do. It doesnt matter how out of shape you are you have to find exercises that are safe for you to participate in.
If your heart rate exceeds your 90% max, then you need to slow down. You dont necessarily have to stop unless slowing down doesnt help your heart rate to decrease. If you exceed your maximum heart rate, then you may need to seek medical attention, especially if you exceed it by large amounts.
As time goes on, you will find that as you get stronger it will take more work for you to get your heart rate to go up as high as you want it. That is the benefit of being a healthy person.
The good news is that, once you meet your weight loss or health goals, then you wont have to worry about getting your maximum 90%. Instead, you will simply want to work toward maintenance, which doesnt require such intense exercise.
Do yourself a favor and invest in a heart monitor that you wear on your wrist so that you can keep track of your heart rate. This will ensure that you meet your goals and dont exceed your maximum safe heart rate at the same time.
What Is Tachycardia And When A High Heart Rate Is Dangerous
- Tachycardia is when your heart rate is faster than normal.
- Sinus tachycardia is a normal increase in heart rate, like when you’re exercising, and it is not generally considered dangerous.
- Other types of tachycardia, like atrial fibrillation, cause a prolonged or recurring high resting heart rate these types are considered dangerous and doctors will recommend treatment.
- This article was reviewed by John Osborne, MD, PhD and the Director of Cardiology for Dallas-based State of the Heart Cardiology.
- This story is part of Insider’s guide to Heart Disease.
Tachycardia is a type of arrhythmia when your heart rate is faster than normal. A healthy resting heart rate for most adults is between 60 and 90 beats per minute , but adults with tachycardia usually have a resting heart rate greater than 100 bpm.
Here’s what you need to know about what causes the different types of tachycardia and when the condition is considered dangerous.

What Happens If You Exceed Your Maximum Heart Rate
It is possible to exceed the upper limit of your zone without any ill effects, as long as you do not have coronary artery disease or are at risk for a heart attack. What it may do, though, is leave you with a musculoskeletal injury. Exercising above 85% of your target heart rate could bring you sore joints and muscles.
Cyanotic And Acyanotic Congenital Heart Disease
Many doctors classify congenital heart disease as either cyanotic congenital heart disease or acyanotic congenital heart disease. In both types, the heart isnt pumping blood as efficiently as it should. The main difference is that cyanotic congenital heart disease causes low levels of oxygen in the blood, and acyanotic congenital heart disease doesnt. Babies with reduced oxygen levels may experience breathlessness and a bluish tint to their skin. Babies who have enough oxygen in their blood dont display these symptoms, but they may still develop complications later in life, such as high blood pressure.
Is A Heart Rate Of 210 Dangerous When Exercising
This is how you can calculate it: Subtracting your age from the number 220 will give you your maximum heart rate. Suppose your age is 35 years, your maximum heart rate is 185 beats per minute. If your heart rate exceeds 185 beats per minute during exercise, it is dangerous for you.
How To Check Your Heart Rate
According to certified personal trainer Marianna Johnson, MSW, a good time to check your heart rate is right after you wake up, while youre still in bed. Johnson, owner of Mind Body Health & Fitness in Falls Church, Virginia, says a midday reading is also fine if taken after a few minutes of rest.
To take your heart rate, place your index and middle finger on your wrist or the side of your neck to locate your pulse. Count the number of beats in a minute.

Atrial Or Supraventricular Tachycardia
Atrial or supraventricular tachycardia is a fast heart rate that starts in the upper chambers of the heart. Some forms of this particular tachycardia are paroxysmal atrial tachycardia or paroxysmal supraventricular tachycardia .
With atrial or supraventricular tachycardia, electrical signals in the hearts upper chambers fire abnormally. This interferes with electrical impulses coming from the sinoatrial node, the hearts natural pacemaker.
The disruption results in a faster than normal heart rate. This rapid heartbeat keeps the hearts chambers from filling completely between contractions, which compromises blood flow to the rest of the body.
A profile for atrial or SVT
In general, those most likely to have atrial or supraventricular tachycardia are:
- Women, to a greater degree than men
- Anxious young people
In extreme cases, those suffering with atrial or SVT may also experience:
Treatment for Atrial or SVT
If you have atrial or SVT, its possible that you wont need treatment.
But if the episodes are prolonged, or recur often, your doctor may recommend treatment, including:
- Some medicinal and street drugs
Other, less common causes may include:
Approach to treatment
How Are Arrhythmias Treated
Many arrhythmias don’t need treatment. For those that do, these options might be used:
- Medicines. Many types of prescription anti-arrhythmic medicines are available to treat arrhythmia. Sometimes, these can increase symptoms and cause side effects, so the patient will be closely watched by the doctor.
- Pacemakers. A pacemaker is a small battery-operated device implanted into the body through a surgical procedure. Connected to the heart by a wire, a pacemaker can detect if the heart rate is too slow and send electrical signals to speed up the heartbeat.
- Defibrillators. A small battery-operated implantable cardioverter defibrillator is surgically placed near the left collarbone. Wires run from the defibrillator to the heart. The ICD senses if the heart has a dangerously fast or irregular rhythm and sends an electrical signal to restore a normal heartbeat.
- Catheter ablation. A catheter is guided through a vein in the leg to the heart. Arrhythmias often are caused by microscopic defects in the heart muscle. Once the problem area of the heart is pinpointed, the catheter heats or freezes the defective muscle cells and destroys them.
- Surgery. Surgery is usually the treatment recommended only if all other options have failed. In this case, a person is put under anesthesia and a surgeon removes the tissue causing the arrhythmia.

Question: What Is Considered A Dangerously High Heart Rate
- Posted On:
Tachycardia refers to a high resting heart rate. In adults, the heart usually beats between 60 and 100 times per minute. Doctors usually consider a heart rate of over 100 beats per minute to be too fast, though this varies among individuals. Factors such as age and fitness levels can affect it.
What Are The Best Exercises To Do If My Heart Rate Is Continually Accelerated
Again, talking to your doctor is a good idea before you start any exercise program or workout plan, especially if you have an accelerated resting heart rate. If you are overweight and you simply have to lose weight for your health, then you may want to start with walking.
In addition, light weight lifting is an excellent way to get your muscles working again, which will aide in the fight to burn off fat faster. Dont lift weights that are too heavy, as this will cause your heart rate to spike. Start low and build up, slow and steady will win the race for you!
This process can be frustrating for many people because it is definitely not the fastest way to lose weight or get into shape. However, once your heart is healthier and your body is stronger, you can do more intense workouts that will accelerate your weight loss and healthy body program.

Why Does Heart Rate Increase When Exercising
Every part of our body needs oxygen and blood at every single second. This need increases when we induce in any kind of physical activity. At the time of exercising, our body needs a much greater amount of oxygenated blood. This is also because during this time our muscles need more energy to respond to the various calls that we make on them to move our body with increased vigor . This is when the heart has to pump more blood into the body parts especially the muscles. This is the why the heart rate experiences a potential increase and eventually the systolic blood pressure also increases. The systolic blood pressure is the blood pressure in the vessels at the time when the heart pumps in the blood into the blood vessels. Hence, this is also an indication that the heart is working harder to pump in a greater amount of blood into the blood vessels and that too at a faster rate.
How Do You Calm A Racing Heart
If you think youre having an attack, try these to get your heartbeat back to normal: Breathe deeply. It will help you relax until your palpitations pass. Splash your face with cold water. It stimulates a nerve that controls your heart rate. Dont panic. Stress and anxiety will make your palpitations worse.

Treatment Of Heart Block
Heart block normally only needs to be treated if it’s causing symptoms.
Depending on the cause of heart block and your symptoms, you may need to have a small device called a pacemaker fitted in your chest. A pacemaker is a small battery-operated device inserted under the skin of your chest. It sends frequent electrical pulses to keep your heart beating regularly.
Treatment for heart block usually works well. Most people live a normal active life with a pacemaker.
What Is Considered A Fast Heart Rate
The definition of a fast heart rate differs depending on the age of the person experiencing it. Typically, it is defined as have a resting heart rate faster than 100 beats per minute for adults.
A fast heart rate is one that is unexpected for a certain level of physical activity. Usually, most adults resting heart rate usually lies in the range of 60-80 beats per minute, with some heart rates approaching 100 beats per minute.

Low Blood Pressure When Blood Pressure Is Too Low. A pulse rate that is constantly above 80 needs to be discussed with a doctor. This is usually their resting pulse rate. A high pulse rate can indicate an increased risk of a heart attack. For adults, the normal pulse rate is considered to be around 60 beats per minute.
What Causes Congenital Heart Disease
Congenital heart disease occurs as a result of an early developmental problem in the hearts structure. The defect typically interferes with the normal flow of blood through the heart, which may affect breathing. Although researchers arent exactly sure why the heart fails to develop correctly, suspected causes include the following:
- The heart defect may run in families.
- Taking certain prescription drugs during pregnancy puts a child at a higher risk for a heart defect.
- Using alcohol or illegal drugs during pregnancy can increase a childs risk of having a heart defect.
- Mothers who had a viral infection during the first trimester of pregnancy are more likely to give birth to a child with a heart defect.
- Increased blood sugar levels, such as occurs with diabetes, may affect childhood development.

Types Of Fast Heart Rate
Fast heart rates can occur in different parts of your heart. Doctors identify different types of fast heart rate, related to the location in which they occur. These include:
- , often referred to as afib: a rapid, caused by irregular electrical impulses in the atria, which are the upper chambers of your heart. Afib is the most common type of tachycardia.
- Atrial flutter: A rapid, regular heartbeat, sometimes experienced by people who also suffer from atrial fibrillation
- Sinus tachycardia: This occurs when your body responds to stimuli such as exercise or emotional distress with a normal increase in heart rate.
- Supraventricular tachycardia : A fast heartbeat that starts above the lower chambers of the heart
- Ventricular tachycardia : A rapid rate caused by abnormal electrical signals in the lower chambers of the heart, called ventricles. Episodes of VT that last longer than a few seconds can be life-threatening.
- Ventricular fibrillation: A fast rate that occurs when rapid, irregular electrical impulses cause the lower chambers of your heart to quiver instead of pumping blood to your body. This type can be deadly and may require your heart to be restored to normal rhythm via electric shock to the heart.
Potential severe complications of fast heart rate depend on which type of tachycardia you have, how fast your heart is beating , how long your rapid heart rate lasts, and whether you have other . Some of the more serious consequences are:

What Causes Them
Your heart has its own electrical system that sends electrical signals around the heart, telling it when to contract and pump blood around the body. The electrical signals start in a group of cells, called the sinus node, located in the right atrium. The sinus node is the heart’s pacemaker and makes sure the heart beats at a normal and consistent rate. The sinus node normally increases your heart rate in response to exercise, emotions, and stress, and slows your heart rate during sleep.
But sometimes the electrical signals don’t “communicate” properly with the heart muscle, and the heart starts beating in an abnormal rhythm this is an arrhythmia .
Arrhythmias can be congenital or happen later, and they can be temporary or permanent.
Arrhythmias also can be due to chemical imbalances in the blood infections diseases that irritate the heart medicines injuries to the heart from chest trauma or heart surgery use of illegal drugs, alcohol, or tobacco caffeine and stress. Arrhythmias also can happen for no apparent reason.
