Sinus bradycardia is a situation in which the heart begins to bark with a frequency of less than 50 barks per minute, at rest; in this type of arrhythmia, barking is slower, but the heart barks on a regular basis, maintaining the same frequency per minute.
Normally, sinus bradycardia does not produce symptoms, however, there is also a decrease in oxygen flow in the heart, people may feel tired, weak and have marine episodes, so it is recommended to consult a doctor, especially with a cardiologist so that he or she takes the corresponding samples and obtains a diagnosis.
- This type of arrhythmias is common in high-level athletes in all bodies and is conditioned by regular physical exertion.
- In childhood this may be the cause of natural heart aging.
- Treatment is guided by the cardiologist based on the symptoms.
- Causes and severity of the episode and may require pacemakers in the most severe cases.
- To avoid complications of bradycardia.
- Regular monitoring with your cardiologist is recommended.
- Learn more about how it works and how you should use a pacemaker.
Sinus bradycardia usually doesn’t cause symptoms, but an episode can start with a lot of withdrawals, usually discovered during your doctor’s office or by using digital pressure devices, which also alter your heart rate. In case of symptoms such as dizziness, fainting, weakness or where a lower heart rate has been detected, it should be evaluated by a cardiologist.
Performing an electrocardiogram (ECG) is used to study and define gravity and guide treatment, also recommending a post-exercise ECG test, also known as an ergometric test, as well as an echocardiogram to evaluate heart structure. 24-hour Holter, which is a test that evaluates whether bradycardia is controlled at any time and whether the individual has a type of heart block.
Your doctor may order certain lab tests to check if sinus bradycardia is related to infections, hypothyroidism, or changes in electrolyte levels (calcium or potassium) in your blood, for example.
Disinfection of the cortex of the heart can cause many people and people who exercise regularly, such as cyclists and athletes, for example, to be considered normal, it is also normal to produce plenty of food after a blood donation when a nasogastric tube is introduced.
However, bradycardia can be caused by certain cardiac or physiological conditions, even if the most common:
In less common situations, sinus bradycardia can occur due to viral or bacterial infections, such as diphtheria, acute rheumatoid arthritis, or myocarditis, which is inflammation of the heart muscle caused by a viral or bacterial infection.
Consequences of sinus bradycardia may include
In this way, to combat these diseases, the cardiologist must be assisted to perform the corresponding tests to initiate appropriate treatment. In some cases, bradycardia may develop a heart block, if a pacemaker is needed for the heart to form properly. It is considered serious in cases where the person has pain in his condition and has associated heart disease.
Treatment can be indicated by the cardiologist and is determined by the cause, symptoms and severity of the episode, that of an underlying disease, if it is the cause of bradycardia, the change in medication that the patient is taking. In more severe cases, the use of a pacemaker may be necessary, which is a device that is surgically placed to regulate the barking of the heart in the event of bradycardia.
To avoid the appearance of bradycardia and this leads to the appearance of symptoms and possible complications, it is recommended to carry out the periodic tests indicated by the cardiologist, and the use of certain medications that could lead to bradycardia should be evaluated.
