What is sick sinus syndrome in children?

summary

Sick sinus syndrome in children is caused by the organic change of sinus node and its surrounding tissue, which makes the formation and efference of impulse disorder or failure. Clinically, there are a series of arrhythmia manifestations such as sinus bradycardia, sinus quiescence, sinus block, bradycardia and tachycardia alternation, and symptoms of different degrees of insufficient blood supply to brain, heart and kidney. What is sick sinus syndrome in children? Next, I'd like to share my views with you.

What is sick sinus syndrome in children?

Due to bradycardia or sinus static, can cause heart, brain, kidney, gastrointestinal and other organs of insufficient blood supply symptoms, mild fatigue, dizziness, chest tightness, palpitations, anorexia, memory loss, severe can occur - Stokes syndrome, and even sudden death.

Because of the rapid frequency of junctional escape rhythm in children, the symptoms are mild and difficult to be found. In a few cases, shock, congestive heart failure or embolism occurred due to the influence of rapid ectopic rhythm on cardiac function.

Surface electrocardiogram (including Holter electrocardiogram) showed obvious and persistent sinus bradycardia without other reasons. The heart rate was divided into 90 beats / min under 1 year old, 70 beats / min between 1-6 years old and 50 beats / min above 7 years old. ② Sinus bradycardia accompanied by sinus block, sinus arrest or escape. ③ Sinus bradycardia and ectopic tachycardia occur alternately, also known as fast slow syndrome. ④ Prolonged slow escape rhythm. ⑤ The P wave is low or bimodal, and the time is widened, which indicates the presence of atrial block.

matters needing attention

Active prevention of congenital heart disease; We should actively prevent and treat all kinds of myocarditis, cardiomyopathy and myocardial damage, actively improve the surgical methods, avoid damaging the sinus node and its surrounding tissues, and strengthen the postoperative treatment to prevent the occurrence of sick sinus syndrome.
