What should I do if the electrocardiogram detects sinus arrhythmia? Cardiovascular doctor tells you

Hello, I am Dr. Zhixinlan.

Nowadays, many people go to the hospital for physical examination, and electrocardiogram examination is almost a must-do examination. "Sinus arrhythmia" is often reported. What's the problem? what to do? Then let’s find out.

1. What is sinus rhythm?

The reason why we can beat continuously now depends on the electrical conduction in the heart, which is commonly known as bioelectricity. There are some special cardiomyocytes in the heart, which are used to conduct cardiac electricity. These structures include the sinoatrial node, atrioventricular node, His bundle, left bundle branch, right bundle branch, Purkinje fibers, etc. Among them, the sinoatrial node is the highest command center, which means that the conduction signal of the heartbeat is transmitted by the sinoatrial node. The knot comes out. This electrical rhythm is called sinus rhythm. Therefore, sinus rhythm is normal.

2. Let’s talk about “uneven”

“Uneven” literally means uneven. A completely normal heartbeat is very regular. For example, if a person's heartbeat is 50 beats/minute, then the interval between each heartbeat is 60 seconds, 50=1.2 seconds. On the basis of sinus rhythm, if the interval between two heartbeats exceeds this value or is lower than this value, and the difference exceeds 0.12 seconds, that is to say, it is greater than 1.2 0.12=1.32, or less than 1.2-0.12=1.08, then An electrocardiogram can diagnose sinus arrhythmia.

3. What causes sinus arrhythmia?

(1) There are many types of heart diseases, such as heart valve disease, myocarditis, cardiomyopathy, pericardial disease, coronary heart disease, etc. These disease states may cause sinus arrhythmia. When you have these diseases, there are usually some symptoms, such as chest tightness, chest pain, palpitation, shortness of breath, cough, sputum, hemoptysis, edema and other symptoms. Doctors can find clues such as heart murmur through physical examination. Of course, You can also use auxiliary inspection to clarify.

(2) What is more common is that many young people and children do not have any symptoms. Doctors have found no abnormalities in physical examinations, and there are no problems in color ultrasound and other examinations. It was only during the physical examination that I did an electrocardiogram and found sinus anomaly. This situation may be related to breathing, especially deep breathing. The heartbeat speeds up when inhaling and when exhaling. The electrocardiogram shows sinus arrhythmia.

4. How to treat?

Sinus arrhythmia is generally asymptomatic and does not itself affect health. Therefore, simple sinus arrhythmia does not require any treatment and is a physiological phenomenon. If it is caused by other reasons, then it is a different matter. How to judge whether it is physiological or pathological? You only need to go to a cardiologist to see it. It is not difficult to identify.
