heart rate - the number of heartbeatsper unit time (typically per minute).It is believed that the heart rate - is the same as that of the pulse, but it is not.

What is the difference in heart rate by pulse

As already mentioned, the heart rate shows how much heart rate does, namely its lower divisions - the ventricles - per minute.

pulse or heart rate - the number of arteries extensions at the time of ejection of blood the heart per minute.Blood when passing through the vessels during the cardiac contraction creates a bulge in the arteries, as determined by touch.

magnitude of heart rate and heart rate, in fact, may be equal, but not always, but only in healthy people.

example, in violation of the heart rate is reduced randomly.If it is reduced twice, the left ventricle did not have time to be filled with blood.Thus, the s

econd reduction occurs when empty ventricle, and from the aorta and peripheral blood vessels are not ejected.Therefore, the pulse in the arteries will not be heard, while the heart beat occurred.In atrial fibrillation, and some other diseases of the heart rate does not match the frequency of the pulse.This phenomenon is called the pulse deficit.In such cases, it is impossible to determine the heart rate by measuring the heart rate.This can be done only by listening to heartbeats, for example, using stethoscope.

atrial fibrillation
At deficiency pulse heart rate is greater than a pulse.Usually it happens in atrial fibrillation and arrhythmia

Norma

The normal heart rate in adults is 60 to 80 beats per minute.If the frequency is less than 60 - a bradycardia if higher than 80 - tachycardia.

resting heart rate will vary depending on:

  • person's age;
  • his sex;
  • body size;
  • fitness.

In newborn infants, the rate is usually 120-140 beats per minute.If the baby is premature, the value will be higher - from 140 to 160. In children, it was reduced to 110-120, for five years - up to 100, to 10 - 90 to 13 - to 80.

HR

have trainedhuman heart rate below normal and the average is about 50, while leading a sedentary lifestyle, it can reach 100 beats alone.Women

heart rate is higher in men than about 6 strikes and further increases before a menstrual period.

a healthy elderly person a normal heart rate is 80 beats normally.If this figure had risen to 160, it indicates the presence of a serious illness.

When changes

different meanings at different times of the day.The indicator changes throughout the day depending on the following factors:

  • during physical activity;
  • in moments of anger, fear, anxiety and other emotions;
  • depending on the body position (lying, sitting, standing);
  • postprandial;
  • after taking certain medications.

heart rate increases after a meal, especially hot and protein.

With an increase in body temperature to 37 degrees increased by 20 strokes.

During sleep, reduced by five to seven units.

heart rate increases by approximately 10%, when the person is sitting, and by 20% when necessary.

heart rate increases:

  • while being in a stuffy, hot room;
  • in times of stress;
  • during exercise.

Causes of tachycardia and bradycardia

If the heart rate at rest is not correct, then it may be a sign of disease.Normally this there are other manifestations of the disease.

If tachycardia is accompanied by symptoms such as dizziness, shortness of breath, weakness, fainting, it is not excluded:

  • infectious disease;
  • heart disease;
  • the beginning of a stroke;
  • endocrine disorders;
  • diseases of the nervous system;
  • neoplastic processes;
  • anemia.

normal bradycardia may occur in the following cases:

Yet we advise to read: Cardiogram tachycardia What if palpitations
  • in athletes (40 strokes);
  • people engaged in heavy physical labor;
  • when taking certain medications.

It can be a sign of disease:

  • poisoning;
  • infarction;
  • stomach ulcers;
  • hypothyroidism;
  • myocardial inflammation.

How to measure

heart rate is measured at rest in a quiet and warm place.For the procedure you will need a stopwatch, and aide.About an hour before the measurement is necessary to eliminate the physical and emotional stress and smoking.Do not take drugs, drink alcohol.

A doctor examines a child
To measure heart rate, you need to attach the hand to the chest

man who will measure heart rate, can lie down or sit.After he takes the right position, you have to lie or sit for five minutes.

Assistant applies the clean dry palm to the chest below the left nipple in men and for breast cancer in women.

necessary to assess the impact of the rib cage in the apex of the heart, called the apical impulse.He tapped half of healthy people in the fifth intercostal space, if the person is standing.If it is impossible to determine, then it falls on the edge.

After that, you need to take a stopwatch and start counting the contraction of the heart in man for a minute.Improper rhythm is necessary to do it for three minutes, then the resulting number is divided into three.

Measure heart rate can be in other places, where the arteries come close to the surface.Well palpable ripple:

  • on the neck,
  • under the clavicle,
  • his temple,
  • shoulders,
  • on the thigh.

When measuring the pulse, to obtain more accurate results, you need to do it on both sides of the body.

The girl measures the pulse itself
athletes need to monitor the heart rate during exercise Maximum heart rate

This is the largest number of beats per minute, which can make heart.This indicator is used by athletes to know what the maximum load you can expose the heart.

It is best to determine the maximum heart rate of clinically, ie it has to do with the help of a cardiologist and ECG treadmill.

There is one easy way to find out the possibility of his heart, but the result is only an approximation.Maximum heart rate is determined by the formula:

  • for men - 220 minus age;
  • for women - 226 minus age.

Conclusion

heart rate refers to the important indicators of the heart.Like the heart rate, it is widely used in medicine for diagnostic purposes, as well as in sport, to follow the intensity of your workouts.
