[Indications for an implantable cardioverter/defibrillator]

Area of Science:

• Cardiology
• Electrophysiology
• Medical Devices

Context:

• Life-threatening ventricular tachyarrhythmias necessitate advanced therapeutic options.
• Implantable cardioverter-defibrillators (ICDs) are the sole effective treatment for these conditions, utilizing antitachycardia pacing or shock.
• Prospective, randomized ICD trials have reshaped the indications for primary and secondary prevention of sudden cardiac death.

Purpose:

• To outline the current indications for implantable cardioverter-defibrillator (ICD) implantation based on established guidelines.
• To provide physicians with essential diagnostic procedures and risk parameters for identifying patients who would benefit from ICD therapy.
• To facilitate adequate ICD therapy in clinical practice for patients at risk of sudden cardiac death.

Summary:

• Implantation of an ICD after identifying a patient at risk significantly reduces both cardiac and total mortality.
• A clear diagnostic pathway and precise risk parameter identification are crucial for optimal patient selection.
• Adherence to current guidelines ensures appropriate and effective ICD utilization.

Impact:

• Improved patient outcomes through significant reduction in mortality.
• Enhanced clinical decision-making for physicians managing patients with ventricular tachyarrhythmias.
• Wider and more appropriate application of life-saving ICD technology in primary and secondary prevention.
