Implantable cardioverter defibrillators (ICDs) continuously monitor your heart to treat tachycardia (fast heart beats) and prevent sudden cardiac death. If a dangerously fast heart rate is detected, a small, painless electrical signal is sent to correct it. If the faster heart rate continues, the ICD is designed to deliver a life-saving shock and restore the heart to a more normal rate.
For Tachycardia (Fast Heartbeat)
If you have tachycardia, your heart may beat up to 400 times per minute. This can cause dizziness, lightheadedness, or a fluttering in the chest. An implantable cardioverter defibrillator continuously monitors your heart and delivers life-saving therapies to treat dangerously fast heart rhythms.
For Sudden Cardiac Arrest
Sudden cardiac arrest occurs when your heart beats so fast it quivers instead of pumping blood to the body and brain. Untreated, it can lead to death in minutes. If you are at risk, it's good to know that an implantable defibrillator can provide ongoing protection.
