What is sinus 20 and what is sinus heartbeat

The electrocardiogram shows that sinus is normal Feeling tightness in the heart may be a mental factor It is recommended to do an electrocardiogram at the time of feeling this to see if it is normal.

Sinus heartbeat is also called sinus arrhythmia.

The judgment is based on the pulse or the heartbeat. 60 beats per minute is normal, and when it is between 50 and 60 per minute, it is generally considered sinus arrhythmia. However, there are some people who have a heart in the range of 50-60 because they exercise a lot, but they do not have a heart disease.

There are also many athletes, and their hearts usually beat at 40-50, which is also normal.

The best test for this is to bring an instrument in the hospital, which is very simple, observe for a day, do not delay you to work, and then go to the hospital the next day to take it out and take a look, observe at any time, or don't care about it at all, this is best to go to the hospital to listen to the doctor's opinion, because everyone's specific situation is different.

A person's normal heart pacemaker is in the sinus node, and the heart rate emitted is called sinus rhythm, which is normal.

The sinus node automatically and rhythmically generates an electric current that is transmitted to various parts of the heart in the sequence of conductive tissues, causing contraction and relaxation of cardiomyocytes. It is from here that the normal heartbeat of the human body is emitted, which is the "pacemaker". The heart beats once every impulse occurs in the sinus node, which is medically called "sinus rhythm".

A normal heart must have a normal sinus node, and a normal sinus node has strong automaticity. The frequency of the sinus node is 60,100 beats per minute, but the heart rate of 25% of young people is 50,60 beats, and it can exceed 100 beats for children before the age of 6 and 100,150 beats for newborn babies.

The irregularity of agitation from the sinus node and the significant uneven cardiac cycle are called sinus arrhythmias.

The sinus node is the highest "headquarters" of the human heartbeat, and the normal sinus node has strong automaticity. The heart rhythm formed by the agitation of the sinus node is collectively called sinus rhythm. The frequency of the sinus node is 60,100 beats per minute, but the heart rate of 25% of young people is 50,60 beats, and it can exceed 100 beats for children before the age of 6 and 100,150 beats for newborn babies.

Many people, especially young people, are often diagnosed with "sinus arrhythmia" during a physical examination of an electrocardiogram. Most people know that the heartbeat should be regular and regular, so when they hear about "irregular heartbeat", many people think that it is abnormal, but doctors often say, "There is no need to treat it."

In fact, "sinus arrhythmia" is a normal physiological phenomenon, not a disease. "Sinus arrhythmia" is most common in children and adolescents, and it is not uncommon in adults. In general, the heartbeat rhythm is regular and regular, and if the heart does not beat in an irregular rhythm, we call it an arrhythmia.

In this sense, "sinus arrhythmia" is the most common type of arrhythmia, which is caused by incomplete regularization of signals from the sinus node. Most of the "arrhythmias" belong to "respiratory sinus arrhythmia", which is a normal physiological phenomenon, which is characterized by changes with breathing, the heart rate can increase several beats when inhaling, and can slow down the number of beats when exhaling, and its fast and slow cycle is exactly equal to a breathing cycle, and the heart rhythm becomes regular when holding the breath.

Sinus rhythm is the normal heart rate, the heart is the organ that pumps blood outward with regular beats, and the sinus node is a piece of tissue located in the adventitia of the right atrium of the heart. Under normal circumstances, the sinus node is the pacemaker of the heart's activity, which can automatically and rhythmically generate current, and can also control the normal activity rhythm of the heart. The normal frequency of the sinus node is 60-100 beats, if it exceeds 100 beats, it is called sinus tachycardia; If the heart rate is less than 60 beats, it is called sinus bradycardia; If the origin of the sinus rhythm does not change, but the rhythm is irregular, it is called sinus arrhythmia.

Whether the above conditions are necessary, you should go to the hospital and ask a cardiologist to make a comprehensive judgment based on the patient's symptoms and other conditions.

This is normal, the sinus node is the pacemaker of the heart, and the ECG report is generally sinus rhythm, so you can consult a doctor if you don't understand.

It is the normal beating of the heart, which is sinus rhythm, because the heart beats through the sinus node. That's why it's called sinus rhythm.

Sinus rhythm. That is, the normal heart rhythm, which is the heart rhythm of the normal pacemaker. It represents the absence of arrhythmias.

SDNN: Standard deviation of all sinus heart rate RR interval (NN interval for short). The unit of mold leakage is ms.

SDANN: standard deviation of the mean of the RR interval. The divination position of a single book is ms.

Normal reference value.

RMSSD: The root mean square of the difference between adjacent RR intervals.

Normal reference value.

PNN50: The difference between adjacent NNs and the number of 50ms as a percentage of the total number of sinus beats.

Sinus rhythm is not spinal normal.

The normal human heart beats rhythmically all the time, and there is a command system that directs the heart to beat regularly, and the starting point of this command system is the sinus node, which transmits its excitatory impulses downwards (sinus node--- internodal bundle--- atrioventricular node --- left. The right bundle branch ---Purkinje's fibers) up to each muscle fiber, forming Sakurayama's heartbeat. Because the rhythm of excitatory impulses comes from the sinus node, it is called sinus rhythm.

Sinus arrhythmias can occur in the presence of disease. The law of the heart of the borderline is wise. Premature atrial contractions.

premature ventricular contractions, etc. So the doctor is right when he says "the heart is fine".

The pain you are talking about is not the heart aching, it may be the pain that occurs when the intercostal nerves are affected by inhalation.
