How to prevent arrhythmia in daily life? Will arrhythmia lead to myocardial infarction?

Arrhythmia means the heart beats too fast or too slow. It is normal to have mild arrhythmia, but if arrhythmia is left unchecked, it may develop into a thinner myocardium, coronary heart disease and other diseases. So first of all, we should start with daily prevention.

How to prevent arrhythmia in daily life

Arrhythmia is caused by coronary heart disease, rheumatic heart disease, myocarditis, cardiomyopathy, acute heart failure, acute myocardial infarction, etc. It is also related to endocrine disorders, drug effects, central nervous system diseases, etc.

The main measures to prevent arrhythmias are:

1. When the weather changes significantly, that is, when the temperature rises or drops suddenly, it is easy to induce or aggravate arrhythmia. Therefore, you should add or remove clothes in time, take good protection, and avoid sudden cold or heat stimulation.

2. Eat a high-protein, high-vitamin, low-salt, low-fat diet that is light and easy to digest. Do not overeat, eat less greasy food, fried food, barbecued food, pickled food (such as mustard tuber, pickled vegetables, bacon, bacon), etc. Do not drink strong tea or coffee, quit smoking and limit alcohol. Especially do not drink strong alcohol.

3. Pay attention to the combination of work and rest, do not stay up late, ensure adequate sleep, go to bed early and get up early, avoid overwork. Exercise moderately, such as Tai Chi, dancing, aerobics, brisk walking, etc., exercise for 30 minutes a day, 5 days a week.

4. Mood changes are closely related to the occurrence of arrhythmia. Keep a calm mind, avoid emotional ups and downs, avoid falling into anxiety and depression for a long time, and adjust tension, depression, anxiety and other emotions in time. You can often read, draw, listen to music, plant flowers and plants, go on outings, etc. to adjust your mood and cultivate your temperament.

5. If you are overweight or obese, you should lose weight and maintain a normal weight.

6. Eat more fresh vegetables and fruits to keep bowel movements smooth. Drink less strong tea, coffee and other beverages.

7. Have regular physical examinations to check blood lipids, blood sugar, blood pressure, electrocardiogram, etc.

Can arrhythmia cause myocardial infarction?

There are many causes of arrhythmia, and myocardial infarction is only one of them.

There are many types of arrhythmias that can be caused by myocardial infarction:

(1) Ventricular arrhythmia.

Including ventricular premature beats, paroxysmal ventricular tachycardia, ventricular flutter, ventricular fibrillation, etc. The cause is that the myocardial cells at the edge of the myocardial infarction site are damaged but not dead due to ischemia. The cell membrane structure of these damaged cells changes abnormally, resulting in changes in the ion concentration difference inside and outside the cell membrane. The excitability of the cell's electrical impulses increases, and electrical impulses are sent out from time to time to seize control of the heart.

(2) Intraventricular conduction block.

Including left and right bundle branch block, 1-3 atrioventricular block. This block can be permanent or temporary. If myocardial infarction causes necrosis of myocardial electrical conduction fiber bundles, then the conduction block is permanent. If the myocardial infarction site is not on the path of the myocardial conduction fiber bundle, the electrical conduction fiber bundle is not necrotic but is affected by the adjacent myocardial necrosis, and inflammatory edema and other lesions occur, the electrical conduction fiber bundle will have a temporary conduction block.

(3) Atrial arrhythmia.

Usually myocardial infarction occurs in the ventricles, but sometimes the atria can also be affected. Therefore, myocardial infarction may also cause arrhythmias such as atrial premature beats, atrial tachycardia, and atrial fibrillation, as well as intra-atrial conduction block and sinoatrial conduction block.

(4) Escape beats and escape rhythm.

There are atrial escape beats, junctional escape beats, and ventricular escape beats. Strictly speaking, they are not arrhythmias. They are beneficial because the lower-level pacemakers compensate to control the heartbeats when the higher-level pacemakers of the heart cannot pace normally or the conduction pathways are blocked to maintain life. For example, when atrioventricular block occurs, the electrical impulses from the sinoatrial node (the highest-level pacemaker of the heart) are unable to conduct and stimulate ventricular contraction. Long-term ventricular arrest can lead to cerebral ischemia, syncope, and even death. At this time, autonomous ventricular pacing (escape beats) can help save lives.

What are the effects of arrhythmia on the human body?

Different types of arrhythmias have different effects on the human body. Premature heart beats due to excessive work, alcohol, tobacco, coffee, etc. will not have a significant impact on the human body, but some serious arrhythmias have adverse effects on health, such as severe bradycardia causing cerebral ischemia, ventricular fibrillation, ventricular tachycardia and other malignant arrhythmias can also directly lead to sudden death.

In any case, slow arrhythmias are not necessarily pathological. For example, strictly speaking, bradycardia is also common in healthy people without heart disease, so there is no need to treat bradycardia. However, if it occurs, we have to go to the hospital for diagnosis.
