Most of us have hearts that work normally. They constantly pump blood through our bodies. But sometimes hearts don’t work like we expect. When they stop working suddenly, it can be fatal so we need ways to get the heart in working order when it falters. This is Implantable Defibrillators with Smartshock™ Technology- Explained- Let’s take a look at how your heart works. It is a muscle, just like the muscles that control the rest of your body, but you don’t have to think to make your heart muscles work. They just keep beating automatically They work because electricity is constantly running through them causing them to contract It’s this electricity that keeps your heart pumping in a regular rhythm and you, alive Unfortunately that electricity can become chaotic causing your heart to beat dangerously fast heart to be dangerously fast – – so fast that it stops pumping blood. This chaotic heart beat is called sudden cardiac arrest or SCA and it can be fatal. Thankfully we have ways to jump-start the heart and return it to a normal heart beat. You have probably seen scenes on TV where a doctor holds paddles onto someone’s chest , says “clear”, shocks the patient, and waits for the heart beat to come back Those paddles are part of what is called a Defibrillator, and the Defibrillator works by shocking the heart back to a normal rhythm difficult later The problem is that the Defibrillators are not always available. If you are at risk for SCA you need to find a way to get your heart beat back as fast as possible where ever you are. That is why Medtronic created a Defibrillator that can be with you all the time. That is called an Implantable Cardioverter Defibrillator or ICD. It is tiny, small enough to be implanted just under your skin, and connected directly to your heart. This way, if your heart suddenly stops beating, the ICD will be there to give it a jump-start. Think about that your heart can stop beating in the wilderness or on a boat and the ICD will be there to save your life. That’s like having an ambulance with you all the time. You should also know that patients may experience surgical complications. and or may not receive the benefit of device therapy as expected. With the device, there are surgical limitations and lifestyle limitations such as avoiding exposure to magnets, which may impact device performance. Here is how it works: the ICD is placed in your chest and has wires called leads that reach your heart through veins through veins, These leads detect your hearts rhythm and sends messages back to the ICD. If an irregular rhythm is detected, the ICD springs to action to correct it. Now you might wonder what it feels like for your heart to be jump started. You will feel it when the ICD corrects your rhythm and it may be startling. In the past ICDs sometimes detected more than just fatal rhythms, with some causing shocks at inappropriate times. Medtronic’s new ICD the Protecta with Smartshock™ Technology is specifically designed to recognize a fatal problem and only shock when it is needed. That may mean you may not even know your ICD is there until it really matters. Now you can have peace of mind that an ICD is there to protect you so you can go on with your life without the worry of unexpected shocks.
