An Implantable Cardioverter Defibrillator (ICD) can send two types of electrical impulses to keep the heart in rhythm. Low-energy pacing delivers small, painless electrical impulses to the heart like a pacemaker or series of impulses (over-drive pacing) to correct certain abnormal fast rhythms (pathological tachycardias). High-energy defibrillation (shock) delivers a strong, brief shock when the heart goes into a life-threatening rhythm such as ventricular fibrillation (VF) or ventricular tachyc

ICD: A Life-Saving Shield for the Heart ⚡❤️ An Implantable Cardioverter-Defibrillator (ICD) is a powerful tool in preventing sudden cardiac death (SCD)—but how do we decide who needs one? 🔹 For Heart Failure Patients: ✅ Primary Prevention: If your EF ≤35% despite optimal medical therapy, you may qualify for an ICD to prevent sudden cardiac arrest. ✅ Secondary Prevention: If you’ve already had a life-threatening arrhythmia or cardiac arrest, an ICD is essential to prevent another. 🔹 For Hypertr
