Products Description Lidocaine is a very good local anesthetic, generally taking effect one to three minutes after application and lasting one to three hours. Used to treat mouth ulcers. Its not used very often as a heart rhythm drug, due to concerns about its long-term side effects. Function Clinical studies have shown that the above-mentioned effects of lidocaine are only manifested in the ventricular myocardium and Pus fibers, but have no effect on the sinoatrial node, atrium and atrioventricular node. Therefore, lidocaine is only effective for ventricular arrhythmias, but not for atrial Arrhythmia is ineffective. In recent years, it has also been found that lidocaine has a certain prolongation effect on the refractory period of the atrioventricular bypass, so it also has a certain effect on the arrhythmia associated with WPW syndrome. Application It can inhibit the sodium channel on the cell membrane and has a membrane stabilizing effect. In the ischemic injury site, this effect is more obvious, which can reduce the conduction difference between normal tissue and ischemic tissue and the inconsistency of the refractory period, and can reduce the one-way block phenomenon of Puers fibers, and prevent the reentrant excitation. production. Lidocaine can also reduce myocardial automaticity and increase the ventricular fibrillation threshold, thereby reducing the occurrence of ventricular fibrillation. please contact me via whatsapp+8619831381159.
