Bradycardia

Bradycardia: causes, symptoms and treatment

Bradycardia is a medical term that describes a slowing of the heart rate to less than 50 beats per minute. Sinus Bradycardia is the most common type of bradycardia and is often observed in healthy people, especially athletes. However, bradycardia can also be a symptom of a number of diseases and conditions.

Causes of bradycardia

Bradycardia can occur for many reasons, including:

1. Sinus bradycardia is a normal reaction of the body to physical activity, sleep or relaxation. It may also be a result of increased heart mass in athletes.

2. Arrhythmias are disturbances in heart rhythm that can cause bradycardia. For example, with heart block, the heart's impulses slow, which can lead to bradycardia.

3. Thyroid diseases – hypothyroidism can cause bradycardia.

4. Jaundice is a condition that can cause bradycardia, especially in newborns.

5. Hypothermia – a drop in body temperature below normal can cause a slow heart rate.

6. Vasovagal crisis is the body's response to stress and can cause bradycardia.

Symptoms of bradycardia

Bradycardia may occur without any symptoms, especially in athletes. However, when symptoms occur, they may include:

1. dizziness or feeling weak;

2. Feeling tired or fatigued;

3. Feeling of difficulty breathing;

4. Unusual heart rhythms (arrhythmias);

5. Loss of consciousness.

Treatment of bradycardia

Treatment for bradycardia depends on its cause and symptoms. If bradycardia does not cause symptoms or is not the result of a medical condition, treatment may not be needed. However, if bradycardia causes unusual symptoms or leads to loss of consciousness, treatment may include:

1. Increasing physical activity or changing lifestyle;

2. Medicines that stimulate the heart;

3. Installation of a pacemaker (a medical device that helps the heart beat regularly).

In conclusion, bradycardia is a serious condition that can result from various causes. If you have symptoms of bradycardia, consult a doctor. Your doctor may recommend treatments that will help improve your health and prevent possible complications. It is also important to monitor your lifestyle, engage in regular exercise and eat healthy foods to maintain a healthy heart and reduce the risk of developing bradycardia and other cardiovascular diseases.

**What is bradycardia Bradycardia or bradyarrhythmia** is a slow or irregular heartbeat. In general, a normal heart rate is considered to be between 60 and 90 beats per minute. Bradyarrhythmia is precisely a significant slowing of the pulse - less than 45 beats within one minute. In addition to slowing down the total number of pulse contractions of the cardiovascular system, bradycardia is also manifested by a number of other symptoms: - general weakness; - confusion of thoughts; - drowsiness; - dizziness;

Why does bradycardia occur? There are many reasons, we list the main ones: - reduced activity of the thyroid gland; - brain tumors; - pathological changes in the sinus node of the heart (the area responsible for the very beginning of contraction and determining the heart rate); - psycho-emotional stress; - overwork. - cardiovascular diseases Examples of such diseases are, for example

1. Bradyacardia in the presence of congenital changes. This includes the primary form of bradyarrhythmia with disruption of the normal functioning of the sinus node, post-inflammatory secondary form of bradykinesia, provoked by the formation of a myomastic scar on the sinus node complex, atrioventricular

Bradycardia is a slowdown in cardiac activity, a drop in stroke volume, which can occur as a result of various reasons: myocardial infarction, hypoglycemia, electrolyte imbalance, hypoxia, etc.

To determine the adequacy of cardiac function, it is necessary to examine heart rate and other parameters of the cardiovascular system. A reduced heart rate indicates mild bradycardia, and 30 or less indicates moderate to severe bradycardia. The normal heart rate for an adult is 60-100 per minute.

Bradycardia that occurs outside of medical manipulations, in turn, can be natural and pathological. Natural usually occurs at night and is associated with changes in the physical and mental state of the individual. Ptachological may be a manifestation of certain diseases.

In addition to slow heart contractions, bradycardia on the ECG is characterized by the presence of a sinus rhythm. On this basis, two types of the disease are distinguished: physiological bradycardia and pathological. The first of them is not symptomatic; moreover, it is present equally often in both men and women. Pathological bradycardia is more typical for women due to age (menopause), and is also considered as a sign of cardiovascular diseases, such as myocarditis, drug intoxication, cardiosclerosis and a number of other pathologies.

Treatment for bradycardia largely depends on the causes of the disease. However, in many cases, the therapy does not affect the number of heart beats. Treatment options range from intravenous drips to heart muscle transplants. In any case, the choice of treatment method should be made by a doctor. He also creates the most appropriate set of examinations in order to eliminate the problem and restore work as quickly as possible

**Bradycardia** is a condition characterized by a slow heart rate, in which the pulse is less than 60 beats per minute. This can be either a temporary condition or a permanent sign of serious pathology.

One of the most common types of bradycardia is sinus bradycardia. It occurs frequently in healthy young people and rarely has pathological significance. However, sinus bradycardia can be a symptom of a number of diseases. For example, a decreased heart rate may indicate hypothyroidism, which is a condition associated with a deficiency of thyroid hormones.

In addition, a slow heart rate may indicate the presence of heart failure, which can result from a variety of cardiac and non-cardiac causes. In this case, bradycardia cannot be considered as an independent condition and requires additional diagnostics.

It is important to note that lowering the heart rate to 30-40 beats per minute can lead to serious consequences such as poor performance
