Or when the heart rate is in a dangerous range? Considering that the heart is one of the sensitive muscles in the center of the chest, this matter will be more important. Usually, athletes have a lower heart rate at rest than other people, and this issue will be different for children, infants and pregnant women. In this article, we provide you with very useful information regarding the causes and complications of dangerous heart rate and we recommend you to read it.

How to measure heart rate?

To measure the pulse using your finger, you can firmly press your two middle and index fingers on the part of your body that has a pulse. The inner part of the wrist is one of the most common places to take the pulse, and from other parts of the body to measure the heart rate with these two fingers, we can refer to the side of the neck, the cavity in front of the elbow, and the end of the toe. After you find your pulse, count the pulse for 60 seconds using a stopwatch or count the pulse for 15 seconds and multiply the result by 4.

If the method we mentioned is difficult or you cannot do it, you can try another solution. For this purpose, first place your two fingers next to the neck or trachea or ask someone else to measure your pulse. Of course, due to the progress of science and technology, you can use digital sphygmomanometers, smart wristbands, some sports devices such as treadmills, and even mobile applications to measure heart rate.

With an expert point of view, it can be said that heart rate measurement is done using the following methods:

1. through the main iliac artery
2. through the carotid artery
3. through the pedal pulse
4. through the artery of the arms
5. through the auxiliary pressure device

What causes heart rate to change?

It is normal for your heart rate to change throughout the day in response to exercise, anxiety, excitement and fear, but your resting heart rate should not be too fast or too slow. One of the most common abnormal heart rhythms can be mentioned in patients with atrial fibrillation, in which there is an irregular pattern of the normal heartbeat.

When your heart beats too fast, this is called tachycardia. Tachycardia has different types, and among the reasons for its occurrence, the following can be mentioned:

• anxiety or stress
• fatigue
• High consumption of caffeine
• High consumption of alcohol
• Body electrolyte imbalance (reason for high heart rate and body tremors)
• Fever and chills
• exercise or intense physical activity
• Side effects caused by drug use
• Smoking
• Use of certain drugs (such as cocaine)

The things mentioned above are often the causes of heart palpitations in young people, which arise due to the lifestyle of young people. Of course, according to the obtained statistics, women are more prone to tachycardia due to being emotional.

Also, if your heart rate is too slow, it is called bradycardia, which is very dangerous. Bradycardia often occurs when the heart rate drops below 60 beats per minute. Note that athletes and people who exercise regularly, heart rate less than 60 times per minute is normal for them, but this issue is considered a disorder for normal people.

Among the causes of heart rate changes in the experience of bradycardia, the following can be mentioned:

• Side effects of drugs
• Body electrolyte imbalance
• Obstructive sleep apnea (cause of high heart rate during sleep)

What is the sign of high heart rate?

High heart rate, which is known in English as high heart rate, is a state in which a person feels his heartbeat abnormally in the chest, neck and throat. When a person's heart palpitations are accompanied by faster beating and disturbance in the functioning of the human heart, it usually causes stress and anxiety in the person.

Some thyroid gland patients who also have low blood sugar levels will witness a high heart rate. In these patients, various symptoms such as dry skin, lack of sleep, hoarseness of voice, body tremors, shortness of breath, etc. are observed.

In some cases, people with anemia have palpitations and experience symptoms such as fatigue, paleness, and weakness. A high heart rate may also be due to serious heart problems and types of heart disease, although this is very rare. In such cases, the person may have symptoms such as chest pain, confusion, severe shortness of breath, and fainting.

If a person feels a high heart rate along with numbness and tingling in the limbs, it can be a sign of an anxiety attack or severe anxiety. In some cases, a disturbance in electrolytes causes such a reaction in a person, among which hyperkalemia, hypocalcemia, and hypomagnesemia can be mentioned.

Maximum heart rate

What do you think is a dangerous heart rate? Knowing your maximum heart rate helps you figure out the ideal heart rate during exercise. You can subtract your age from 220 to estimate your maximum heart rate and get it. For example, a 30-year-old person should have a maximum heart rate of 190.

220-30=190

This means that the maximum heart rate for a 30-year-old person is 190 beats per minute. Calculating this number will be very useful for people who exercise, and you can find out if you have enough energy to exercise or not.

What is a dangerous heartbeat?

According to a group of people Cardiologist in Isfahan in order to determine how dangerous the heart rate is, it is necessary to examine the heart rate of a person under different conditions. But a healthy adult has a heart rate between 60 and 100 beats per minute, and a heart rate outside this range is considered a dangerous heart rate range. In fact, a dangerous heartbeat is when a person's heart beats too slowly or too fast.

Range of normal heart rate at different ages

The range of normal heart rate is different in different ages and it can be said that the normal heart rate changes depending on the age and conditions of the person. We will examine this issue in the following.

• An adult resting has a normal heart rate of 60 to 100 beats per minute, which varies according to age group and gender. It is interesting to know that the normal heart rate of women is on average 2-7 BPM faster than that of men. Also, the heart rate of young athletes will be up to 40 BPM. It should be noted that the range of 57 to 61 beats per minute is considered an excellent range.
• The number of normal heartbeats for babies is 100 to 160 beats per minute, while this number will be 90 to 150 beats per minute for babies aged 0 to five months. Children aged 6 to 12 months have a normal heart rate of 80 to 140 beats per minute, and this number for children aged 1 to 3 years is 80 to 130 beats per minute.
• Normal heart rate in 3 to 5 year old children is 80 to 120 beats per minute and 60 to 10 year old children have a normal heart rate of 70 to 110 beats per minute. Meanwhile, the number of normal heart beats in children aged 11 to 14 is equal to 60 to 10 beats per minute.
• The normal heart rate for women is different from that of men, and at rest, they have a heart rate between 60 and 100 beats per minute. It should be noted that the normal heart rate of women during pregnancy is 10 to 20 beats per minute due to increased blood volume and hormonal changes, and in some cases this number may exceed 90 beats per minute.

Complications of high heart rate

A high heart rate is generally due to harmless things that ultimately increase the heart rate and make the heart pump harder. Of course, in all these cases, the person experiences extreme discomfort and fears death, but in fact, no danger threatens him. However, in rare cases, we have seen complications. In the following, after examining the question of how much is a dangerous heart rate, we will learn about the most common complications of a high heart rate.

If you do not take the treatment of high heart rate seriously, in some cases your heart may become weaker and this increases the risk of heart failure.

• Fainting

In some cases, wisdom may lose consciousness due to high heart rate, and this increases the risk of falling or other accidents.

• sudden death

This case is one of the rarest complications of high heart rate in patients, which usually occurs only with high ventricular heart rate or ventricular fibrillation.

Among other common side effects due to high heart rate, we can mention a decrease in blood flow to vital organs and a decrease in cardiac output and symptoms such as dizziness and weakness.

Conclusion

In this article, we examined why the heart rate increases and explained the signs of a dangerous heart rate. A heart rate above 120 may be dangerous for an adult, but this number is normal for some children.

You can use your two fingers to measure your heart rate at home, and if you find it difficult, you can get digital blood pressure monitors. Be careful that if your heart rate is continuously more than 100 or less than 60 beats per minute, it is better to see a doctor. پزشک در واقع ممکن است شما را به آنژیوگرافی در اصفهان ارجاع دهد ولی تا مشخص شدن نتیجه نهایی هیچ ترسی نداشته باشید.
