If the heartbeat is too fast, heart failure and shock may come to you! Reminder: If you exceed this number, you should be vigilant
Uncle Guo, 73, suffers from coronary heart disease and heart failure. Recently, I often felt flustered. Later, when I talked with the neighbors, I learned that Betaloc can treat heart failure and can help to slow down the heartbeat, so Uncle Guo tried to double the dose of Betaloc.
However, after taking Betaloc, Uncle Guo's palpitation symptoms did not relieve significantly, but instead he felt fatigued. One day on the way to the vegetable market, Uncle Guo's eyes turned black and he fell directly to the ground. The neighbors immediately sent him to the emergency room of a nearby hospital.
Uncle Guo suffered from acute left heart failure, and he was not rescued at the hospital in the end.
Every year in China, many people experience sudden cardiac death and arrhythmia. The normal heart contracts rhythmically, and sometimes some habits may induce abnormal heartbeats.
1. American study: alcohol may increase the frequency of atrial fibrillation
Atrial fibrillation is one of the more dangerous arrhythmias. Researchers from the University of California, San Francisco, USA, launched a randomized clinical trial called I-STOP-AFib in order to explore the individual triggers of atrial fibrillation.
The researchers took 466 patients with atrial fibrillation as study subjects and used mobile ECG devices and a mobile phone app to test the study subjects for potential atrial fibrillation triggers, such as caffeine, diet, sleep, alcohol consumption, exercise, etc.
The researchers controlled and tested the triggers of atrial fibrillation in the experimental group, and found that participants in the experimental group reported fewer atrial fibrillation than the control group.
Among the many triggers, alcohol intake is consistently associated with frequent arrhythmias , and patients with atrial fibrillation should avoid alcohol , the researchers concluded .
2. If your heartbeat exceeds this number, you should seek a doctor
Chen Qingyong, the attending physician of the Department of Cardiology, West China Hospital, Sichuan University, introduced: The normal heart rate of people has a range, generally 60-100 beats/min, which originates from the sinoatrial node. If a person's heart rate exceeds 100 beats per minute, it is called sinus tachycardia, and if it falls below 60 beats per minute, it is called sinus bradycardia. In addition, if the origin of the cardiac rhythm is non-sinus node, the condition is called ectopic rhythm.
If the atria do not beat according to the rhythm, then the heart is "beating", which is called atrial fibrillation. When atrial fibrillation occurs, the electrical signal from the atrium to the ventricle is disordered, and cardiac function is also affected due to insufficient blood supply to the ventricle.
During atrial fibrillation, the heart rate can reach 100-200 beats/min, and even more than 200 beats/min . A major clinical feature is arrhythmia. Patients will experience dizziness, rapid heartbeat, palpitation and shortness of breath. There will also be pain. You should seek medical attention as soon as possible.
For hypertensive patients, the increased sympathetic nerve excitability leads to the problem of increased heart rate. On the one hand, the increased heart rate will increase blood pressure. On the other hand, excessive sympathetic nerve excitation will shorten the diastolic time and reduce myocardial blood supply. disease due to injury.
Therefore, a heartbeat of 80 beats per minute is normal for normal people, but it is very dangerous for hypertensive patients, and the judgment criteria for hypertensive patients are as follows:
• In-office measurements >80 times/min
In cases where resting heart rate is measured in the clinic >80 beats/min, patients are advised to perform home resting heart rate measurement (to exclude white coat effect)
• Measurements at home >75 times/min
In the resting state, multiple home self-measured heart rates at different time points were all >75 beats/min, which can be regarded as an increased heart rate.
The heart rate of most hypertensive patients can be controlled at 60-80 beats/min. Here we should pay attention to the elderly with arteriosclerosis or patients with insufficient cerebral blood supply, the heart rate should not be controlled too low.
3. The heart rate is too fast and the crisis is heavy
When the heart rate is too fast, not only the electrical signals sent to the ventricle will be chaotic, but also the efficiency of blood supply to the ventricle will be reduced, which will affect the pumping function of the heart and cause more problems.
Thromboembolism may first occur，When the heart beats fast, the atrium beats irregularly, and the blood in the atrium cannot be fully pumped to the ventricle, which may cause the remaining blood to stay in the atrium and eventually form a thrombus.
If the thrombus flows to the whole body with the blood and falls off, it will enter the veins of the lower extremities and cause vascular embolism in the lower extremities. If the thrombus flows to the brain, it may cause cerebral embolism, and the fatality rate is as high as 63%.
The second is to increase the risk of heart failure. When atrial fibrillation occurs, the patient's heart rate is above 100 beats per minute. At this time, the systolic function of the atrium decreases, resulting in the inability of blood to be pumped out, resulting in a continuous decrease in peripheral blood volume, which may cause heart failure. It can cause symptoms of heart failure such as fatigue and organ failure in patients.
In the end , there may be shock , the blood in the heart cannot be pumped out, and the peripheral circulating blood volume continues to decrease. The patient may have hypotension (less than 90/60mmHg), hypoperfusion, and may even be accompanied by the performance of shock.
4. Is the heartbeat too slow? Below this number, be careful
The previous standard was that the heart rate <60 beats/min can be clearly defined as sinus bradycardia, but according to the newly released "Chinese Expert Consensus 2020 on the Evaluation and Management of Patients with Bradycardia and Conduction Abnormalities", sinus bradycardia is redefined. : Sinus bradycardia is defined as heart rate < 50 beats/min.
Bradycardia is also a disease, but whether it needs treatment depends on whether there are specific symptoms.
• Heart rate <50 beats/min, generally asymptomatic patients do not need treatment
In addition, patients should pay attention to exclude reversible factors such as drugs. If sinus bradycardia is still highly suspected, an electrocardiogram or imaging can be considered for evaluation, and if necessary, a dynamic electrocardiogram or intracardiac electrophysiological examination can be performed.
• Heart rate <50 beats/min, accompanied by fatigue, dizziness, chest tightness, chest pain, forgetfulness, inability to concentrate, easy to get angry, etc., you need to seek medical attention as soon as possible.
How can we stabilize our heartbeat in our daily life?
Reasonable diet: Control salt intake, eat less food with high oil, high salt and high calorie, and drink more water.
Regulate your mood: Be less angry every day, pay attention to a peaceful mind, don’t be impatient, nervous, anxious, you can calm down your mood by listening to music, meditating, etc.
Correct bad habits: pay attention to quit smoking and drinking, drink less strong tea, put an end to the habit of staying up late, ensure regular work and rest, and pay attention to regular bowel movements to ensure smooth bowel movements.
Weight control: Obesity not only affects the appearance, but also increases the burden on the heart. In life, you can maintain a normal weight by controlling your diet and exercising. Calculate the body mass index (BMI = weight (kg) / height (m) squared), generally considered over 24 is overweight, over 28 is obese.
Regular exercise: Regular physical exercise can enhance your cardiopulmonary function. When you first start exercising, it is recommended to perform transitional training, such as jogging, walking, aerobics and other low-intensity aerobic exercise.
Exercise for 30-40 minutes a day. After a period of time, you can increase the intensity and time of exercise according to your own situation.
The exercise heart rate should be basically controlled at 130~160 beats/min for the middle-aged, 120~130 beats/min for the elderly, and 130~140 beats/min for young people.
The heart is the center of our body's blood pumping. Under normal circumstances, the heart beats rhythmically, but once the heart beats too fast or too slow, it is likely to be a distress signal from the body, which needs to be observed, especially in cases of arrhythmia. On the basis, it is also accompanied by dizziness, fatigue, chest pain and chest tightness and other discomforts. It is necessary to seek medical treatment as soon as possible to investigate the cause and treat the symptoms.
