Sinus bradyarrhythmia, how serious is it?

Bradycardia is an important type of arrhythmia. Some patients usually have a slow basal heart rate, about 50-60 beats per minute, or even less than 50 beats per minute, and usually have symptoms of dizziness, fatigue, fatigue, and poor spirit. Some patients can usually have a normal heart rate, bradycardia can appear suddenly, drop to less than 40 beats per minute, dizziness, transient eye black, fatigue, palpitations, chest tightness, shortness of breath, sometimes a sensation of shock in the precordial area, and in severe cases, syncope may occur.

Other patients present with symptoms of dizziness, fatigue, or syncope, and may have prolonged intermittent cardiac arrest during examination.

Recommendation: Required**. In severe cases, the pacemaker should be installed.

No problem, it should be, the normal heart rate is 60 to 100, and some athletes' heart rate is slow, as long as the average heart rate is above 40, and there are no corresponding symptoms, don't worry about it.

Normal people can also have bradycardia, if there are no symptoms, you don't need to **, such as dizziness, chest tightness and other symptoms can go to the hospital for treatment**.

If you are not an athlete and have no bradycardia in the past, you should pay attention to arrhythmias, and regular follow-up and appropriate oral nutritional myocardial drugs are recommended. If there is a persistent slowdown and transmission to the block, it is important to pay attention to early intervention.

Systemic diseases: hypothyroidism, obstructive jaundice, increased intracranial pressure, certain infections such as leptospirosis, typhoid, epidemics, infectious mononucleosis, diphtheria recovery, hypopituitarism, hyperkalemia, alkalosis, esophageal diverticulum, depression, can cause sinus bradycardia.

4) Cardiovascular diseases: acute myocardial infarction, chronic ischemic heart disease, sinus node inflammation, myocarditis, endocarditis, pericarditis invasion and sinus node, thrombosis, dilation, inflammation of sinus node artery, some cardiomyopathy such as amyloidosis, tetralogy of Faroo's disease or large vessel dislocation, microbial involvement of the heart, bleeding into the sinus node, familial sinus bradycardia, central nervous system diseases involving the cardiosuppressive center or acceleration center, etc., can lead to the occurrence of bradycardia.

I have been sick for half a month, and in the hospital I was diagnosed with sinus bradyarrhythmia, with an average heart rate of 45 beats, sometimes chest tightness and chest pain. Dizzy. Panic, how can I ** thank you?

Whether it is congenital sinus bradyarrhythmia.

Hello, less than 60 is called bradycardia. There are several types of bradycardia, the most common being sinus bradycardia. Sinus bradycardia can be divided into pathological and physiological.

Physiological sinus bradycardia is a normal phenomenon, the general heart rate is 50 60 times, athletes may have a heart rate of 40 times, no **, common in normal people sleep, people with more physical activity.

In your case, where the heart rate is slow and frequent episodes of discomfort, consider seeing a doctor for a recent 24-hour Holter guide**. I hope you find my answer helpful and I wish you good health and happiness.

Sinus tachycardia can be seen in healthy people when smoking, drinking tea or coffee, drinking, physical activity and emotional agitation, and certain pathological conditions, such as fever, hyperthyroidism, anemia, shock, myocardial ischemia, congestive heart failure, and the use of drugs such as epinephrine and atropine, can also cause sinus tachycardia.

**。**Mainly for**, sedatives or blockers may be used if necessary.

1.Sinus tachycardia should be the primary cause of the disease, supplemented by symptomatic disease if necessary. Sinus tachycardia caused by congestive heart failure, digitalis preparations, diuretics and vasodilators, etc.

Correction of sinus tachycardia is often used as an indicator of control of left heart failure.

2.For sinus tachycardia not due to heart failure**, such as sinus tachycardia caused by hyperthyroidism, the heart rate cannot be slowed with digitalis. Note:

Excess digitalis can also cause sinus tachycardia. Patients with sinus tachycardia mainly caused by sympathetic nerve excitation and catecholamine elevation can choose receptor blockers, sedatives, etc.

3.In patients with acute myocardial infarction** In the absence of clear cardiac insufficiency, the sinus heart rate lasts for 110 minutes, in order to slow the heart rate, a low-dose receptor blocker (such as oral atenolol or a calcium antagonist (such as oral thiiazeprozone 15 30 mg) can be temporarily tried, and it can be taken once every 8 12 hours if needed. Sinus tachycardia secondary to left heart failure should be managed primarily for heart failure.

If it is sinus tachyarrhythmia caused by drinking strong tea, coffee, emotional stress, exercise or injection of adrenaline, it is a normal physiological reaction, but if it is due to anemia, myocarditis, hypotension, hyperthyroidism, fever and other diseases, arrhythmia is needed. The patient goes to the hospital for an examination** and then symptomatic treatment**.

Systemic diseases: hypothyroidism, obstructive jaundice, increased intracranial pressure, certain infections such as leptospirosis, typhoid, epidemics, infectious mononucleosis, diphtheria recovery, hypopituitarism, hyperkalemia, alkalosis, esophageal diverticulum, depression, can cause sinus bradycardia.

4) Cardiovascular diseases: acute myocardial infarction, chronic ischemic heart disease, sinus node inflammation, myocarditis, endocarditis, pericarditis invasion and sinus node, thrombosis, dilation, inflammation of sinus node artery, some cardiomyopathy such as amyloidosis, tetralogy of Faroo's disease or large vessel dislocation, microbial involvement of the heart, bleeding into the sinus node, familial sinus bradycardia, central nervous system diseases involving the cardiosuppressive center or acceleration center, etc., can lead to the occurrence of bradycardia.
