What effects does the heartbeat have on the body if the heart beats too fast?

The human heart beats about 2.

The frequency and rhythm of the heartbeat reflect the health of the body, under normal circumstances, the heart is like a clock with rhythmic beating, once it exceeds the normal rhythm, it may affect lifespan

Life Times (search for "LT0385" within WeChat to follow) interviews experts to tell you what changes your heartbeat overdrive brings to your body and teaches you to steady your heartbeat

Experts interviewed

Shi Weibin, deputy chief physician of the Department of Cardiovascular Medicine of the Army Special Medical Center

Hou Xiaofeng, deputy chief physician of the Department of Cardiology, Shanghai Sixth People's Hospital

Heartbeat overdrive can affect lifespan

The beating of the heart is initiated by the sinus node, the supreme headquarters of the pacing and conduction system, called sinus rhythm

The level of the heart rate in the resting state can reflect the health of the heart to some extent, and 60 to 100 beats per minute is considered to be within the normal range

Greater than 100 beats / min, sinus tachycardia;

More than 150 beats/min may present with supraventricular tachycardia, atrial fibrillation, atrial flutter, etc.

What effects does the heartbeat have on the body if the heart beats too fast?

To live a long life, it is best to control the resting heart rate below 75 beats

If the heart is in a state of high-speed operation for a long time, it is necessary to complete contraction and relaxation in a short period of time, which will cause the oxygen supply of the myocardium to be reduced, resulting in insufficient blood supply to the heart and myocardial ischemia; It also increases myocardial oxygen consumption, leading to enlarged heart and heart failure

//

Although slow heart rate is generally considered to be beneficial to healthy longevity, this slowness is also limited, and if it is less than 60 beats per minute, it is considered

Severe beat of the heart (less than 45 times / min) is easy to cause blood flow slower, the blood supply to the organs of the whole body oxygen supply becomes poor, patients will have dizziness, fatigue, chest tightness, shortness of breath and other adverse reactions, serious will be life-threatening

In addition to the above, the heart rate may also occur irregular rhythm, that is, irregular heart rhythm, often accompanied by panic, shortness of breath, chest tightness, and unstable sleep at night

What is quietly affecting the heartbeat?

Heart rate is related to factors such as age, exercise, spirit, diet, mood, etc.

The causes of tachycardia can be divided into two types

Physiological factors

Changes in position, physical activity, anxiety, agitation, alcohol consumption, smoking can occur, usually without special treatment

Pathological factors

It includes systemic diseases such as fever, anemia, hypoxia, infection, hyperthyroidism, and cardiovascular diseases, such as heart failure, hypertension, myocarditis, acute myocardial infarction and other organic heart diseases

Tachycardia caused by physiological factors, if combined with organic cardiovascular diseases, such as coronary heart disease, hypertension, etc.
, may also cause serious events
such as angina, myocardial infarction, and cerebrovascular accident.

In addition, dehydration, insomnia and tiredness, long-term use of certain drugs (steroids, diet pills, and drugs containing caffeine, atropine, thyroid-stimulating hormones, heart anticoagulants, etc.
), may also have rapid heartbeat problems
.

Deceleration method for cardiologists

People with a rapid heartbeat should first know if they have heart disease, anemia, hyperthyroidism, or other chronic underlying disease
.

Excluding pathological factors, the heart rate does not exceed 100 beats per minute, generally does not require treatment, and the heartbeat can be slowed down
by exercise, lifestyle adjustment and other methods.

Stick to regular exercise

Regular exercise of appropriate intensity will make the heart function exercised
.
Studies have found that if you insist on exercising for at least 3 months, you can reduce your heart rate by 4 to 5 times per minute
.

It is recommended to exercise 3 to 5 times a week for 20 to 60 minutes each time, excluding warm-up and finishing exercise
after the end.
Recommended jogging, brisk walking, swimming, badminton, tai chi, etc
.

Pay attention to monitoring your heart rate when exercising, in general, it is more appropriate
to exercise your heart rate about 20 times faster than your resting heart rate.

Internationally accepted formula: exercise heart rate = 170 - age; For frail and older people, the exercise heart rate = (170-age) × 0.

Maintain the right weight

Obesity will increase the burden on the heart, and weight loss is one
of the effective means of lowering heart rate.

The Body Mass Index (BMI) is an important way
to assess obesity.
In our country, it is generally considered that BMI exceeding 24 is overweight and BMI exceeding 28 is obese
.

Avoid negative emotions

Anger, excessive stress and anxiety will cause the heart rate to accelerate, and the mentality in life should be kept as peaceful as possible, and calm can be gradually restored by listening to music, meditation and so on
.

Get rid of bad habits

Staying up late, smoking, drinking alcohol, lack of sleep, etc.
, can all speed up
the resting heart rate.
Drink less strong tea, especially not before bedtime; Regular bowel movements should also be made to keep bowel movements smooth
.

Consult a doctor before taking the drug

Certain medications can raise heart rate, such as cold medicines, asthma inhalants, and certain antidepressants
.
Be sure to consult a doctor before taking to avoid side effects
such as tachycardia.

If the heartbeat is still fast after correcting the above factors, and the patient has palpitation and other discomfort, it is necessary to see a specialist and take some drugs
to slow down the heart rate as directed by the doctor.
