Postural Orthostatic Tachycardia Syndrome
A person with postural orthostatic tachycardia syndrome may experience an increased heart rate upon standing up. They may also experience dizziness and a drop in blood pressure.
POTS is a condition of the autonomic nervous system. It happens because this system does not properly regulate bodily functions such as blood pressure, heart rate, or breathing.
What Is Considered A Dangerously High Heart Rate
A normal heart rate in a healthy adult range from 60 to 80 beats per minute at rest, Infants and children has higher heart rates than adults in the normal state. The heart rate can rise during exercise, running, high fever, flu, excitement, consumption of nicotine or caffeine, surgical operations, and treatment procedures. When heart rate in adults exceeds 100 beats per minute at rest, then the condition is called tachycardia which has a pathological reason behind. It becomes extremely dangerous for the patient as it may cause heart failure, cardiac arrest, and even death.
What Things Affect Heart Rate
Other than exercise, things that can affect your heart rate include:
- Weather. Your pulse may go up a bit in higher temperatures and humidity levels.
- Standing up. It might spike for about 20 seconds after you first stand up from sitting.
- Emotions. Stress and anxiety can raise your heart rate. It may also go up when youâre very happy or sad.
- Body size. People who have severe obesity can have a slightly faster pulse.
- Medications. Beta-blockers slow your heart rate. Too much thyroid medicine can speed it up.
- Caffeine and nicotine. Coffee, tea, and soda raise your heart rate. So does tobacco.

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.3
In the age category closest to yours, read across to find your target heart rates. Target heart rate during moderate intensity activities is about 50-70% of maximum heart rate, while during vigorous physical activity its about 70-85% of maximum.
The figures are averages, so use them as a general guide.
How Many Beats Per Minute Before You Have A Heart Attack
Can your heart rate reveal your risk for a heart attack? A very high or very low heart rate may reveal your risk for heart attack. For most people, a heart rate thats consistently above 100 beats per minute or below 60 beats per minute for nonathletes should prompt a visit to a doctor for a heart health evaluation.

Causes Of High Heart Rate Variability
A high HRV is known to be a sign of a healthy heart. Most of the studies have found that a higher HRV is associated with lowered morbidity and mortality and enhanced psychological well-being and good quality of life.
Often, the most common cause of high heart rate variability is due to the continuous low-grade stressors. These stressors in the short term lead to a higher HRV as the body is continuously making an effort to recover from the situation.
Maximum And Target Heart Rate
Its important to know what your maximum heart rate should be to avoid causing harm to your heart or body. To calculate your maximum heart rate, subtract your age from 220. According to the American Heart Association , your target heart rate while doing moderately intense activities should be about 50% to 70% of your maximum heart rate. During vigorous exercise, it should be about 70% to 85% of your maximum heart rate.
If you exceed your maximum heart rate, you may experience sore joints, sore muscles, or musculoskeletal injuries. Heart rate monitors are great to wear while exercising because they tell you your heart rate in real-time.
What Is A Normal Exercising Heart Rate
To determine what a normal exercising heart rate is, you first need to determine your age-predicted maximal heart rate. Here is the generalized equation for predicting maximal heart rate in healthy adults:
HRmax = 208
For example, a 20-year-old person, the age-predicted maximal heart rate would be 194 beats per minute and for a 65-year-old person, the age-predicted maximal heart rate would be 163 beats per minute. A simplified age-predicted maximal heart rate equation is commonly used, but it overestimates maximal heart rate in young adults and increasingly underestimates the maximal heart rate in older adults.
How To Lower Your Heart Rate
Staying physically active by doing moderate to vigorous exercise regularly is one of the best ways to achieve a lower heart rate that leads to a healthy and long life.
Changes in your lifestyle that may lower your heart rate include:
- Reducing the intake of coffee and caffeine-containing products
- Avoiding binge drinking
- Intake of a healthy diet to keep weight under check
- Doing deep breathing to manage stress and anxiety
If your heart rate becomes too high suddenly, and you feel shortness of breath or chest pain, you need to consult your doctor immediately to get medications prescribed for you. This could be a sign of an impending heart attack or other life-threatening heart problems.

What You Can Do
Additionally, you should plan to visit your doctor regularly for physicals. Not only is it good practice, but it can also help with early detection of things like 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.
Some additional preventative health tips to help keep your heart healthy and happy include:
- Find ways to reduce stress. Examples of ways to do this can include things like yoga or meditation.
- Limit your caffeine intake. Using too much caffeine can lead to increases in heart rate.
- Moderate your drinking. Women and men over 65 should only have one drink per day. Men under 65 should only have two drinks per day.
- Quit smoking. Smoking increases your heart rate and quitting can help bring it back down.
- Be aware of medication side effects. Some medications can affect your heart rate. Always be aware of possible side effects before taking a medication.
Your heart is a muscular organ that works to pump oxygen-rich blood and nutrients to the tissues of your body. The muscles of your heart contract and relax to push blood through your blood vessels.
How To Determine Your Ideal Resting Heart Rate
Well-trained athletes may have a resting heart rate between 30 and 40 bpm. But everyones heart rate is different. Theres no ideal resting heart rate, even though a lower resting heart rate may mean youre more fit.
You can measure your resting heart rate at home. Take your resting heart rate by checking your pulse first thing in the morning.
- gently press the tips of your index and middle finger over the lateral part of your wrist, just below the thumb side of your hand
- count the beats for a full minute

How Do You Stimulate The Vagus Nerve
The vagus nerve is also called the pneumogastric nerve or cranial nerve. The nerves are referred to as afferent, meaning that they transmit information to the brain through many of the internal organs.
The vagus nerve bundle travels all over the body . We have access to our vagus nerves at the carotid arteries and behind our eyes. Applying gentle pressure over the left carotid artery, or directly on the eyeballs, sends a stimulating impulse along the vagus nerve. The massaging tells the brain to slow the heart rate. The right vagus tends to increase heart rate. If you are ever uncertain about whether to massage the right or left, go ahead and do both. The overall effect is balancing and the heart will most likely return to a normal rhythm.
What Is Heart Rate Variability
Heart rate variability is the measurement of the autonomic nervous system that is largely believed to be one of the finest objective metrics for physical strength and determine the bodys readiness to perform any action.
HRV is literally the difference in time between the beats of the heart. So, if the heart rate is 60 beats per minute, it is not in reality beating once per second. Within that said minute there could be 0.9 seconds between 2 beats, for instance, and 1.15 seconds between 2 other beats. The higher this difference is, the more prepared the body is to act at a higher level.

How To Determine Your Ideal Exercising Heart Rate
Some athletes like to follow target-heart-rate training. This is based on your intensity level compared to your maximum heart rate.
Your maximum heart rate is considered the highest amount your heart can sustain during cardiovascular training. To calculate your maximum heart rate, subtract your age from 220.
Most athletes train at between 50 and 70 percent of their maximum heart rate. For example, if your maximum heart rate is 180 bpm, your target-training zone would be between 90 and 126 bpm. Use a heart rate monitor to keep track during exercise.
What Does A Blood Pressure Reading Of 200/100 Mean
Readings above 180 systolic pressure indicate a hypertensive crisis even if your diastolic pressure is below 110. This is because the worse reading is used when systolic and diastolic pressure fall into different ranges.
Extremely high blood pressure can cause headache, nausea, vision changes, mental confusion, chest pain and shortness of breath. It is considered a hypertensive emergency if you have a blood pressure reading over 185/110 combined with any of these symptoms. Call 911 and seek medical attention immediately.
Doctors may also diagnose you with hypertensive urgency when you dont have any symptoms but your blood pressure remains high. Whether a hypertensive emergency or hypertensive urgency, its important to bring your blood pressure down as soon as possible.
Uncontrolled high blood pressure can lead to chronic damage of arteries and organs. Untreated, this can result in enlargement of the heart, heart failure and kidney damage, which may require dialysis.
Unfortunately, many dont have any symptoms even with very high blood pressure. So it remains important to get your blood pressure checked on a regular basis.

Heart Rate Variability Range
The studies on Heart Rate Variability of late have taken a leap due to the fact that HRV has evolved as the most interesting & trustable marker for research studies related to resilience and behavioral flexibility. Although many think Heart Rate and HRV are one and the same they arent so. To be more precise, HRV is something like an advanced version of HR which is a more systematic, scientific and reliable method to know your strength to perform an act. The standard heart rate variability range is something anywhere from below 20 to over 200 milliseconds.
Elevated Heart Rate Most Likely Caused By Medical Condition
May 6, 2011
What is sinus tachycardia? What causes it? How is it treated?
Sinus tachycardia is the term used to describe a faster-than-normal heartbeat a rate of more than 100 beats per minute versus the typical normal of 60 to 70 beats per minute. Well over 99 percent of the time, sinus tachycardia is perfectly normal. The increased heart rate doesn’t harm the heart and doesn’t require medical treatment.
The term sinus tachycardia has nothing to do with sinuses around the nose and cheeks. Rather, it comes from the sinus node, a thumbnail-sized structure in the upper right chamber of the heart. This structure controls the heart rate and is called the heart’s natural pacemaker.
The sinus node signals the heart to speed up during exercise or in situations that are stressful, frightening or exciting. For example, a 10- to 15-minute brisk walk typically elevates the heart rate to 110 to 120 beats per minute. Also, the sinus node increases the heart rate when the body is stressed because of illness. In all of these circumstances, the heart rate increase is a normal response.
Likewise, the sinus node signals the heart to slow down during rest or relaxation.
For some patients, the elevated heart rate is the only symptom. Some have a lifelong history of sinus tachycardia in the 110 beats per minute range, and they lead a normal, healthy life. And often the inappropriate sinus tachycardia will improve in time without treatment.

What Heart Rate Is Too High
Generally, for adults, a heart rate of more than 100 beats per minute is considered as high.
Your heart rate usually rises when you walk fast, run, or do any strenuous physical activities.
Maximum heart rate and Target Heart Rate
Before doing any vigorous exercise, you should know your maximum heart rate and target heart rate, both of which vary by age.
Going beyond your maximum heart rate is not healthy for you. Your maximum heart rate depends on your age. 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.
- Your target heart rate zone is the range of heart rate that you should aim for if you want to become physically fit. It is calculated as 60 to 80 percent of your maximum heart rate.
- Your target heart rate helps you to know if you are exercising at the right intensity.
- It is always better to consult your doctor before starting any vigorous exercise. This is especially important if you have diabetes, heart disease, or you are a smoker. Your doctor might advise you to lower your target heart rate by 50 percent or more.
Given below are the table showing the target heart rate zone and maximum heart rate as per age.
How Can I Quickly Lower My Heart Rate
Close your mouth and nose and raise the pressure in your chest, like youre stifling a sneeze. Breathe in for 5-8 seconds, hold that breath for 3-5 seconds, then exhale slowly. Repeat several times. Raising your aortic pressure in this way will lower your heart rate.

What Is A Dangerous Heart Rate
A number of conditions can impact your heart rate. An arrhythmia causes the heart to beat too quick, too slow or with an irregular rhythm.
Tachycardia is normally considered to be a resting heart rate of over 100 beats per minute, according to the National Institutes of Health, and generally triggered when electrical signals in the hearts upper chambers fire unusually. If the heart rate is closer to 150 bpm or higher, it is a condition known as supraventricular tachycardia . In SVT, your hearts electrical system, which controls the heart rate, runs out whack. This usually requires medical attention.
Bradycardia is a condition where the heart rate is too low, generally less than 60 bpm. This can be the result of issues with the sinoatrial node, which functions as the pacemaker, or damage to the heart as an outcome of a heart attack or heart disease.
What Is A Normal Heart Rate
A normal resting heart rate is usually between 60 and 100 beats per minute. Your number may vary. Children tend to have higher resting heart rates than adults.
The best time to measure your resting heart rate is just after you wake up in the morning, before you start moving around or have any caffeine.

What Is A Normal Or Resting Heart Rate
There are three general ways to classify heart rate, 1) normal, 2) fast and 3) slow.
- A resting heart rate is normal between 60-100 beats per minute.
- A resting heart rate is fast at greater than 100 beats per minute.
- A resting heart rate is slow at less than 60 beats per minute.
A resting heart rate predicts longevity and cardiovascular disease, and current evidence suggests that it is also an important marker of outcome in cardiovascular disease, including heart failure. A normal heart rate is generally stated to be between 60-100 beats per minute at rest . However, recent studies have suggested that an ideal resting heart rate is between 50-70 beats per minute. It is well-known that the average resting heart rate for well-trained athletes is between 40-60 beats per minute! A heart rate can change dramatically while sleeping or with daily activity and exercise. Usually, a heart rate will be slower during sleep, faster during daily activities or with exercise, and recover quickly back to a resting rate after exercise. This means your heart has appropriate heart rate variability and recovery, which is associated with good heart health. Your resting heart rate can also be used to estimate how much energy your body uses, or your basal metabolic rate.
