Sinus arrhythmia

When it comes to heart disease, many people feel that only middle-aged and elderly people are prone to heart diseases. In fact, children are also susceptible to some heart diseases. For example, sinus arrhythmia is a heart disease that is more common in children. It is for this reason that I hope that parents and friends can have a better understanding of sinus arrhythmia.

The reason why sinus arrhythmia occurs is generally related to the influence of some drugs, such as morphine, digitalis, etc. If a child takes these drugs, it is easy to cause sinus arrhythmia. So, if there is sinus arrhythmia, what are the clinical manifestations?

Children's symptoms are milder than those of adults and they often lack complaints. Some older children may describe palpitations, chest tightness, and discomfort. Often detected by auscultation or electrocardiogram, sinus arrhythmia may be related to the respiratory cycle, which speeds up during inhalation and slows down during exhalation. Sinus arrhythmia was of no clinical significance.

ECG characteristics

(1) Respiratory sinus arrhythmia Sinus P wave; arrhythmia is related to breathing, slowing down during exhalation, speeding up during inhalation, and the heart rhythm becomes regular when holding the breath; on the same lead, the PP interval differs by more than 0.12 seconds;

(2) The symptoms of non-respiratory sinus arrhythmia are basically the same as those of respiratory sinus arrhythmia; the arrhythmia has nothing to do with the respiratory cycle.

treat

The treatment of sinus tachycardia is mainly to eliminate the inducement, such as pain relief, infection control, anemia correction, improvement of cardiac function, control of hyperthyroidism, etc. If necessary, appropriate beta-blocker treatment can be given. However, it should be noted that sinus tachycardia is mostly caused by physiological stress response, so beta-blockers should not be used in large quantities unless the inducement is eliminated to prevent excessive cardiac inhibition.

Sinus bradycardia can be observed if the heart rate is above 40 beats/minute. For patients with severe sinus bradycardia, if the treatment is ineffective or cannot be improved, a pacemaker needs to be installed to prevent heart failure.

This article provides a targeted introduction to the causes, symptoms and treatments of sinus arrhythmia. Although the disease is not very harmful to the human body, it does have a certain impact on the growth of children. Therefore, if you find that your child has symptoms of sinus arrhythmia, please take your child to the doctor for treatment in time.
