In pacing terminology, what does ICD stand for?

In pacing terminology, ICD stands for Implantable Cardioverter-Defibrillator. This device plays a critical role in the management of patients at risk for life-threatening arrhythmias. The ICD continuously monitors the heart's rhythm and can deliver electrical shocks when it detects a dangerous and potentially fatal heart rhythm, such as ventricular fibrillation or tachycardia.

ICDs are particularly important for patients who have a history of these arrhythmias or certain types of heart diseases that increase their risk of sudden cardiac arrest. By being implanted inside the body, the ICD can intervene quickly, often saving lives by restoring a normal heart rhythm. The ability of the device to not only pace the heart but also to sense and treat arrhythmias distinguishes it from other types of cardiac devices, emphasizing its crucial role in cardiac care.
