lidiya [134]

Implantable cardioverter-defibrillator (ICD)

The nurse should implement the treatment of implantable cardioverter- defibrillator treatment to prevent an SCD recurrence at home.

  • The most popular method for preventing SCD recurrence is an ICD.
  • When a patient lives at home on a daily basis, an external pacemaker may be utilized in the hospital but not there.
  • To determine whether a recurrence is likely and to identify the best medication to treat it, an EPS may be performed.
  • Although they are utilized, medications to treat dysrhythmias do not offer the best protection against SCD.

<h3>What is the mechanism of an implantable cardioverter defibrillator?</h3>
  • The electrical system of the heart is reset by a brief burst of electrical current delivered by an implantable cardioverter defibrillator (ICD) if the heart rhythm suddenly becomes dangerously rapid and possibly life-threatening (which can result in a cardiac arrest).

AfilCa [17]

Answer:

Option (D).
