Question

What is the post-sinus node dysfunction or AV block treatment?

1) Implantation of a pacemaker
2) Administration of medication
3) Surgical intervention
4) Monitoring the condition
5) None of the above

Answer 1

The primary treatment for AV block or post-sinus node dysfunction is the implantation of a pacemaker to ensure effective cardiac rhythm and blood flow. Medications and careful condition monitoring are additional treatments, while surgical interventions are less common.

Step-by-step explanation:

The treatment for post-sinus node dysfunction or AV block can include a variety of approaches depending on the severity and type of block. Among these treatments, the implantation of a pacemaker is a common intervention when arrhythmias become chronic and the heart maintains a junctional rhythm. A pacemaker delivers electrical impulses to stimulate the heart muscle, ensuring effective contraction and blood circulation. Besides pacing, a pacemaker can provide defibrillation if built-in defibrillators are present. Medications may be administered to manage symptoms or to attempt to restore a normal heart rhythm, but they are more commonly used for arrhythmias causing a fast heart rate. In some cases, careful monitoring of the condition may be the chosen strategy to understand the progression and determine if further action is needed. Surgical interventions may be considered in certain complex or refractory cases.
