Normal heart rate, Resting heart rate, 60 to 100 beats

Normal Heart rate

Heart rate per minute (BPM) is the rate of the heartbeat measured by the number of contractions (beats) of the heart. Heart rate can vary according to the physiological needs of the body, including the need to absorb oxygen and excrete carbon dioxide. It is usually equal to or close to a pulse measured at a peripheral point. Activities that provoke change may include physical exercise, sleep, anxiety, stress, illness, and ingestion of drugs.

The American Heart Association stated that normal resting adult human heart rates are 60–100 bpm. Tachycardia is a rapid heart rate, defined as a rest above 100 bpm. Bradycardia is a slow heart rate, defined as a rest below 60 bpm. During sleep, slow beats with a rate of 40–50 bpm are normal and are considered normal. When the heart does not beat in a regular pattern, it is called arrhythmia. Heart rate abnormalities sometimes indicate disease

Normal heart rates at rest:

  • Children (ages 6 – 15) 70 – 100 beats per minute
  • Adults (age 18 and over) 60 – 100 beats per minute

Low heart rate factor

Heart rate can be slowed by altered sodium and potassium levels, hypoxia, acidosis, alkali, and hypothermia. The relationship between electrolytes and HR is complex, but maintaining electrolyte balance is important for the normal wave of depolarization. Of the two ions, potassium is of greater clinical importance. Initially, both hyponatremia (low sodium levels) and hypernatremia (high sodium levels) can cause tachycardia. Severely high hypernatremia can lead to fibrillation, which can lead to discontinuation of CO. Severe hyponatremia leads to both bradycardia and other arrhythmias. Hypokalemia (low potassium levels) also leads to arrhythmia, while hyperkalemia (high potassium levels) makes the heart weak and flaky, and eventually fails.

Heart muscle relies exclusively on aerobic metabolism for energy. Severe hypoxia (insufficient supply of oxygen) leads to reduced HR because metabolic contractions inhibit heart contractions.

Acidosis is a condition in which more hydrogen ions are present, and the patient’s blood expresses a lower pH value. Alkalosis is a condition in which there are very few hydrogen ions, and the patient’s blood has an elevated pH. Normal blood pH is in the range of 7.35–7.45, so a lower number than this range represents acidosis and a higher number represents the base. Enzymes, being regulators or catalysts for almost all biochemical reactions – are sensitive to pH and will change size slightly with values outside their normal range. These variations in pH and with slight physical changes to the active site on the enzyme decrease the rate of formation of the enzyme-substrate complex, subsequently reducing the rate of many enzymatic reactions, which can have complex effects on HR. Severe changes in pH will cause denaturation of the enzyme.

The last variable is body temperature. Elevated body temperature is called hyperthermia, and suppressed body temperature is called hypothermia. There is little hyperthermia in increasing HR and contraction strength. Hypothermia slows down the rate and strength of the heart’s contractions. This different slowing of the heart is a component of the large diving reflex that gives blood to essential organs when submerged. If cooled sufficiently, the heart will stop beating, a technique that may be employed during open-heart surgery. In this case, the patient’s blood is normally transported to an artificial heart-lung machine to maintain the body’s blood supply and gas exchange until the surgery is complete, and the sinuses The rhythm of the can be restored. Excessive hyperthermia and hypothermia will both result in death, as enzymes drive body systems to stop normal function starting with the central nervous system.

Normal heart rate by age

Normal heart rates at rest:

  • Children (ages 6 – 15) 70 – 100 beats per minute
  • Adults (age 18 and over) 60 – 100 beats per minute

Normal pulse rates at rest, in beats per minute (BPM)

  1. (0–3 months old)infants 99-149
  2. (3 – 6 months)infants  89–119
  3. (6 – 12 months)children 89–119
  4. (1 – 10 years)children over 10 years 69–129
  5. & adults, including seniors well-trained 69–129
  6. adult athletes 39–59

A basal or resting heart rate (HRrest) is defined as the heart rate that occurs when a person is awake, in a neutrally temperate environment, and has not been subjected to any recent stress or surprise. A large body of evidence indicates that the normal range is 60–100 beats per minute. This resting heart rate is often correlated with mortality. For example, when the heart rate exceeds 90 beats per minute, the all-mortality rate increases by 1.22 (hazard ratio). Patients with myocardial infarction increased from 15% to 41%, with a heart rate higher than 90 beats per minute. The ECG of 46,129 individuals at low risk for heart disease revealed that 96% had a heart rate of 48–98 beats per minute. Finally, 98% of cardiologists in one study suggested that 50 to 90 beats per minute over 60 to 100 are appropriate, as is a desirable target range. The normal resting heart rate is based on the resting-rate of the heart’s atrial node. , Where rapid pacemaker cells drive responsible for self-generated rhythmic firing and autorhythmicity of the heart. For athletes enduring at elite levels, it is not uncommon to have a resting heart rate between 33 and 50 bpm.

Maximum and target heart rate

There is no definitive medical advice when the resting heart rate is too high, but most medical experts agree that a sustained heart rate in the upper levels can put a lot of stress on the heart and other organs. If a person has a low heartbeat rate and is experiencing other symptoms, the doctor may examine his heart.

Knowing your heart rate during workout sessions can tell whether you are doing too much or not. When people exercise in their “target heart area”, they get the most benefit and improve their heart health. When your heart rate is in the target area, you know “you’re pushing to strengthen the muscles,” Baumann said.

A person’s target heart rate zone is between 50 percent to 85 percent of his or her maximum heart rate according to the AHA.

Typically, the maximum heart rate is calculated by subtracting your age from 220. For a 30-year-old, for example: 220 – 30 = 190.

The target area of ​​a 30-year-old man will be between 50 and 85 percent of his maximum heart rate:

50 percent: 190 x 0.50 = 95 bpm

85 percent: 190 x 0.85 = 162 bpm

For a 60-year-old man, the target area would be between 80 and 136 bpm.

You can either manually calculate your heart rate during exercise or have heart rate monitors that wrap around the chest or are included in sports watches. [Related: Best Heart Rate Monitor Watches For Exercise]

However, it is not the case that there is no benefit to exercising without achieving a heart rate up to the target area, Booman said.

“Many people are just not doing any exercise that I worry about them reaching their target heart rate and worrying more about getting them out and moving their body,” Bowman said.

Lowering a rapid heart rate

  • The pulse rate may increase due to nervousness, tension, dehydration, and redundancy. Sitting down and taking slow deep breaths can usually reduce your heart rate. Exercising and getting fitter will usually reduce the heart rate.
  • According to AHA, cooling is important after a workout. Because your heart is beating fast, your body temperature is high and your blood vessels are thin, stopping too fast can make you feel sick or pass out.
  • The AHA recommends stretching and walking. Stretching helps reduce the build-up of lactic acid, causing cramps and stiff muscles. Follow these suggestions:
  • Walk for about 5 minutes, or until your heart rate falls below 120 beats per minute.
  • Stretch, and hold each stretch for 10 to 30 seconds. If you feel you need more, then stretch back to the other side and return for another set of stretches.
  • The stretch should be strong, but not painful.
  • Do not jump
  • Breathe while you are pulling. Exhale while stretching.

What is a dangerous heart rate?

If your heart rate is consistently above 100 beats per minute or 60 beats per minute (and you are not an athlete) then you should visit your doctor.

Apart from heart rate, you may have other symptoms like:

Shortness of breath

Syncope

Dizzy or dizzy

Feel your chest fluttering or beating

Pain or discomfort in your chest

Blood pressure vs. heart rate

Some people confuse high blood pressure with a high heart rate. Blood pressure is a measure of the force of blood against the walls of the arteries, while the pulse rate is as often as your heartbeat per minute.

There is no direct connection between the two, and high blood pressure, or hypertension, does not necessarily result in a high pulse rate, and vice versa. Heart activity increases during strenuous activity, but a vigorous workout can only raise blood pressure marginally.
