What are the dangers of tachycardia? Do you understand this common sense?

We all know that the heart is an important organ in the body. The internal structure of the body is very complex and there are many organs, but the heart is one of the most important organs. Once there is a problem with the heart, it will cause great harm to the human body. Sinus tachycardia is a common disease among many people and is very harmful to the body. So what are the dangers of sinus tachycardia?

In adults, the rate of sinus node impulse formation exceeds 100 beats per minute, which is called sinus tachycardia, and the rate is usually between 101 and 160 beats per minute. When sinus tachycardia begins and ends, the heart rate gradually increases and slows down.

In addition, there are many dangers of tachycardia:

1. Arrhythmia can cause blood circulation disorders: When arrhythmia occurs, the contraction process of the atria and ventricles changes, which can cause cardiac output to drop by about 30%, causing the patient to experience symptoms such as guilty conscience, chest tightness, and weakness.

2. Severe sinus rhythm that is too fast can cause sinus arrest, sinoatrial block and bradycardia, resulting in tachycardia syndrome (also known as slow-fast syndrome).

3. Rapid sinus rhythm can lead to sudden death: The most common cause of sudden death is arrhythmia, among which ventricular tachycardia, ventricular fibrillation and conduction block have the highest incidence of sudden death.

4. Sinus tachycardia may be caused by: mental stress, insomnia, anxiety, drinking strong tea or coffee, smoking and drinking excessively, as well as cold and hunger. Other diseases, such as fever, physical weakness, taking anticholesterol drugs, etc. can also cause tachycardia. Of course, all kinds of organic diseases of the heart can cause tachycardia.

5. A fast heart rate can easily lead to atherosclerosis. A fast heart rate can harm health and shorten life expectancy, mainly by increasing the incidence and mortality of cardiovascular diseases. This is because heart rate is a window that reflects the excitability of the sympathetic nerves, and increased sympathetic nerve excitation is one of the important mechanisms for the occurrence and development of many cardiovascular diseases, including hypertension.
