Why does sinus arrhythmia occur? What it is? What are the symptoms associated with? These questions interest many. Indeed, a similar problem is faced by people of different age categories, including children.
Sinus arrhythmia - what is it?
Sinus arrhythmia is a condition that is accompanied by a violation of the normal sinus rhythm: heart contractions either slow down or speed up. Even in a healthy person, from time to time, failures in the rhythm are observed - this is completely normal and natural. In children, this condition is diagnosed during the recovery period after a serious illness. But often attacks of arrhythmia indicate the presence of a serious pathology.
Most often in modern medical practice, respiratory sinus arrhythmia occurs. What it is? A similar condition develops against the background of irregular and uneven formation of nerve impulses, which happens, for example, with vagus nerve irritation . When you inhale, the heart rate doubles, and when you exhale, on the contrary, it decreases. Respiratory arrhythmia is usually found in young people.
Risk factors include hypothyroidism, hypoxia, hypertension, amyloidosis and other conditions that are accompanied by atrial infiltration.
There is no sinus arrhythmia associated with breathing. What it is? Such a violation is most often diagnosed in the elderly, it is associated with a violation of coronary circulation. Insufficient blood supply to the sinus-atrial node leads to heart rhythm malfunctions.
Sinus Arrhythmia: Symptoms
Signs of arrhythmia can have different intensities, depending on the condition of the patient. Quite often, people complain that from time to time they feel strong heart contractions. When the rhythm slows down, an instant appearance of weakness, dizziness, and sometimes fainting is observed.
Often, such attacks are accompanied by severe shortness of breath. Some patients experience a feeling of heaviness or even pain in the heart.
Constant malfunctions of heart contractions often lead to the development of chronic fatigue, decreased performance, constant drowsiness.
Should sinus arrhythmia be treated?
A rapid heartbeat or a sinking heart is an occasion to consult a doctor. In no case should you ignore these symptoms, as they may indicate more serious diseases. An electrocardiogram is the easiest and surest way to determine if sinus arrhythmia is occurring in the heart. Only a doctor can choose treatment .
Mild arrhythmia sometimes does not require any medical procedures. But a persistent violation of the heart rhythm is an alarming signal - the patient needs to undergo a full examination, which will make it possible to determine the cause of such a pathology. First of all, it is necessary to get rid of the primary disease. For example, with hypertension, drugs that dilate blood vessels and normalize blood pressure are used. Patients in serious condition require hospitalization and constant medical supervision.
