How to treat preexcitation syndrome

summary

Many people don't know about the disease of preexcitation syndrome. I believe many people will feel strange when they see the name. Everyone should be very clear in their hearts. Because they are unfamiliar, many people don't know what causes pre excitation syndrome and how to treat it. But it doesn't matter. Today I'll introduce it one by one. If you want to know, come and have a look.

How to treat preexcitation syndrome

First, disease factors (35%) are also found in some congenital heart diseases and acquired heart diseases, such as tricuspid valve depression, hypertrophic obstructive cardiomyopathy, etc. Patients with preexcitation can also have atrial fibrillation or atrial flutter attack. This attack is mostly caused by impulse reverse transmission, which reaches the atrium in the vulnerable period of atrium. When atrial flutter and atrial fibrillation occur, the concealed conduction of impulse in the junction tissue promotes most or all of the impulse to pass to the ventricle through the bypass. The ventricular rate is extremely fast. Atrial flutter or atrial fibrillation with abnormal QRS complex can sometimes develop into ventricular fibrillation.

Second, the cause of body factor (55%) pre excitation is the existence of congenital atrioventricular accessory pathway (bypass) outside the normal atrioventricular conduction system. Most of the patients had no organic heart disease.

Third: treatment of preexcitation syndrome 1. Preexcitation itself does not need special treatment, only in the case of supraventricular tachycardia, it needs to be treated. 2. When complicated with atrial fibrillation or atrial flutter, if the ventricular rate is fast and accompanied by circulatory disturbance, synchronous direct current cardioversion should be adopted as soon as possible. Lidocaine, procainamide, propafenone and amiodarone can slow down the conduction of bypass, slow down the ventricular rate or convert atrial fibrillation and atrial flutter to sinus rhythm.

matters needing attention

Digitalis can accelerate the bypass conduction, verapamil and propranolol can slow down the atrioventricular nodal conduction, which may significantly increase the ventricular rate and even develop into ventricular fibrillation, so it is not suitable for use. If the attack of supraventricular tachycardia or atrial fibrillation or atrial flutter is frequent, the above antiarrhythmic drugs should be taken orally for a long time to prevent the attack.
