Final Answer:
When to give a patient AICD vs biventricular pacing A) AICD is preferred in cases of heart failure with reduced ejection fraction (HFrEF).
Step-by-step explanation:
AICD (Automatic Implantable Cardioverter-Defibrillator) is preferred in cases of heart failure with reduced ejection fraction (HFrEF), as indicated by option A. AICD is specifically designed to monitor and treat life-threatening ventricular arrhythmias, making it a suitable choice for patients with HFrEF who are at an increased risk of sudden cardiac death due to arrhythmias. The device can deliver electrical shocks to restore normal heart rhythm and prevent fatal arrhythmias.
Patients with HFrEF often have a weakened heart muscle, leading to a reduced ability of the heart to pump blood effectively. This condition increases the risk of ventricular arrhythmias and sudden cardiac death. AICD serves as a preventive measure by detecting and treating these arrhythmias promptly. On the other hand, biventricular pacing, mentioned in option B, is commonly used in patients with heart failure and conduction delays to synchronize the contractions of the heart chambers, improving overall cardiac function.
Understanding the specific indications for AICD and biventricular pacing is crucial for healthcare providers involved in managing patients with heart failure. Tailoring the choice of device to the individual patient's condition and needs ensures optimal outcomes in the prevention and management of cardiac arrhythmias.
