What is sinus tachycardia with arrhythmia

Many people have experienced abnormal heartbeats, such as suddenly feeling their heart beating very fast, accompanied by panic, weak legs, etc., and going to the hospital for examination gave the answer that they had sinus tachycardia with irregular heartbeat. In fact, sinus tachycardia with sinus arrhythmia is a normal physiological phenomenon, not a disease. This symptom is most common in children and adolescents, but is also not uncommon in adults.

Sinus tachycardia with sinus arrhythmia will not cause more serious arrhythmias, so no measures need to be taken. You can take Anshen Buxin Capsules and go to the hospital for treatment if necessary.

The difference between sinus tachycardia and arrhythmia

The main difference between the two is the pacemaker.

Sinus tachycardia is paced at the normal pacemaker, the sinoatrial node, but the rate is faster than 100 beats per minute. In children, it is even faster, reaching more than 120 beats per minute.

Supraventricular tachycardia includes atrial tachycardia and junctional tachycardia. The pacemakers of both are not in the sinoatrial node. Atrial tachycardia originates from any part of the atrium except the sinoatrial node, while the pacing of junctional tachycardia originates from the atrioventricular junction. On the electrocardiogram, atrial tachycardia: atrial rate 100~250 beats/minute, often around 150 beats/minute, with sudden arrest.

Strictly speaking, supraventricular tachycardia is not a disease. It can only be said to be a symptom caused by some kind of heart disease, so it is best to go to the hospital for a full check-up.

Causes and prevention of tachycardia

The most common cause of supraventricular tachycardia in Chinese is preexcitation syndrome, accounting for about 60%, double channel atrioventricular node accounts for 30%, and other heart diseases including coronary heart disease, primary cardiomyopathy, hyperthyroidism, digitalis poisoning, etc. account for about 10%. Ventricular paroxysmal tachycardia is often accompanied by various organic heart diseases, the most common of which is coronary heart disease, acute myocardial infarction, mitral valve prolapse, Ebstein anomaly, heart surgery and long QT interval syndrome. It can also be seen in idiopathic tachycardia of organic heart disease. Triggers include exercise, excessive fatigue, emotional excitement, pregnancy, excessive drinking or smoking, etc.

For patients with frequent attacks, oral medications that can control attacks can be chosen, such as isapride, quinidine, or amiodarone for maintenance periods. And the triggers of the attack should be avoided.
