Activity Description

The automated internal cardiac defibrillator or shock box is the common name given to the Implantable Cardioverter Defibrillator (ICD). ICD is a state-of-the-art device that treats arrhythmias specifically those of ventricular origin like ventricular tachycardia and fibrillation. It has become the first line of defense in patients who are at high risk for sudden cardiac death (SCD) and has shown consistent survival benefit in cardiac arrest survivors (SCA), in patients with Heart failure and severe systolic dysfunction (left ventricular ejection fraction-LVEF less than or equal to 35%) as well as in patients with hypertrophic cardiomyopathy (HCM). This activity reviews the indications for an AICD and highlights the role of the interprofessional team in the management of patients with ventricular arrhythmias.

Target Audience

This activity has been designed to meet the educational needs of physicians.

Learning Objectives

At the conclusion of this activity, the learner will be better able to:

  • Identify the indications for an AICD.
  • Describe the contraindications for an ACID.
  • Recall the clinical benefits of an AICD.
  • Discuss interprofessional team strategies for improving care coordination and communication to advance the insertion of an AICD and improve outcomes.

    his was a slipshold job to be sure. in your discussion of class 1 indications for icd, you made serious errors. specifically the "OR" occurring just before the phrase - 40 days post mi, shoudl ceraainly have been "AND" ,. how could this mistake be made, unless no one is proffreading, that actually knows the subject. You could just copy the indications from HRS and hey would be correct. This is serious. I would hope you could let me know when you have fixed this. I will be calling the head of the company if don't soon hear otherwise.
