On the air of the program “About the Most Important Thing” Alexander Myasnikov and invited to the studio expert, cardiovascular surgeon, Ph.D. Vladislav Goryachev They told us why the heart rate can slow down, why it is dangerous, and how this situation can be corrected.
When the heart slows down, they talk about bradyarrhythmia, that is, a rare pulse. “The heart can generate impulses independently in the sinus node and conduct them through the heart into the ventricles,” Goryachev noted.
Myasnikov added that the diagnosis of “sinus arrhythmia” or “sinus rhythm” should not frighten a person, since this is a description of the norm.
“The problem lies in the generation of the sinus node when it does not know how to reproduce the rhythm. Accordingly, everything that should happen is cut off and happens elsewhere. Or there will be a conduction disturbance, when the impulse has formed and passes to the ventricles, but is not carried out at the nodal point. The ventricles suffer, reducing the frequency of their contraction,” said the vascular surgeon.
Symptoms of such failures may include dizziness, loss of consciousness, and fainting.
“Fainting never occurs in a lying position. It’s always lightheaded, dizzy, and you realize that you’re going to fall. If you fell just like that, you were switched off, or it happened while lying down – the reason is always in the heart,” Myasnikov added.
Risk factors for the development of bradyarrhythmia are:
- alcohol;
- smoking;
- diseases such as coronary heart disease, thyroid disease. Hypertension.
All this leads to disruption of tissue trophism and problems in the structures of the heart. A rare rhythm is unsafe. Myasnikov emphasized that special attention should be paid to elderly relatives. Especially patients who have had a heart attack. And if necessary, it is worth installing a pacemaker. However, everything must be individual and according to indications.
