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

How do rhythm devices work 🤔 Heart rhythm devices like implantable cardioverter-defibrillators (ICDs) and pacemakers are lifesaving technologies that help keep your heart beating in sync 💓. Whether they’re detecting irregular rhythms or giving your heart a gentle nudge to stay on track, these devices play a crucial role in preventing dangerous arrhythmias and even sudden cardiac arrest.
