What is a bradycardia?

Bradycardia is a kind of arrhythmia, in which the frequency of heartbeats is less than sixty beats per second. In trained athletes, such a heartbeat can be a variant of the norm, but, as a rule, this is a deviation indicating various cardiac pathologies. Pronounced bradycardia (less than forty beats per minute) may manifest as weakness, short-term loss of consciousness, fainting, pain in the heart, cold sweat, unstable blood pressure, dizziness. It often requires surgery to implant the pacemaker.

What is a bradycardia?

The causes can be very different, but at the heart of this disease is always a violation of the ability of the sinus node to generate electrical impulses, the frequency of which would be above sixty per minute. Either this can be a violation of their spread along the conducing paths. What is bradycardia, you already know, you should also know that with a rare heart rhythm, there may be a lack of blood supply, and as a result - oxygen starvation of tissues and organs that disrupts the full functioning of the body. At high physical exertion (especially in men) bradycardia can be considered the norm, and at night the heart rate can be reduced by thirty percent. But often the cause is any pathology.

What is the danger of a bradycardia?

Any deviation from the norm is not good. Especially when it is associated with the heart. What is bradycardia - understandable, but how can it be dangerous? It is not difficult to guess: oxygen starvation clearly can not lead to anything good. Sooner or later it will still make itself felt. Remember that a pronounced form can not be tolerated. The lack of oxygen in the brain can lead to Morgagni-Adams-Stokes attacks, which are a manifestation of a dangerous syndrome characterized by frequent loss of consciousness. The attack can lead to even more unpleasant consequences: violation of the heart rhythm, chaotic contractions of individual cells of the myocardium, and this eventually threatens the depletion of the heart muscle. Possible fibrillation of the ventricles is dangerous by a heart attack.

Symptomatics

What is bradycardia in practice? With a moderately severe form of circulatory disorders, there is practically no. The clinical picture of the symptoms manifests itself only with a pronounced bradycardia. The patient exhibits rapid fatigue, weakness, a tendency to fainting, impaired concentration, short-term vision disorders. The usual manifestation of this ailment is a violation of hemodynamics.

Can it be prevented?

Timely detection of bradycardia can help prevent many problems. Diagnosis and treatment is determined by a cardiologist after a thorough examination, which may take some time. Keep in mind that a bradycardia can be hereditary: if your relatives have this disease, you should undergo a test that will reveal it at an early stage.
