A Holter monitor is a small, wearable device that keeps track of the heart rhythm. It shows the size and structure of the heart and how blood flows through the heart. This imaging test uses sound waves to create moving pictures of the heart. An ECG can show if the heart is beating too fast or too slowly. Wires connect the electrodes to a computer, which displays or prints the test results. Sticky patches called electrodes are placed on the chest and sometimes the arms and legs. An ECG is a quick and painless test that checks the heartbeat. This complication, called cardiac perforation, is rare.īefore you get an ICD, several tests are done to check your heart health. Movement of the device or leads, which could lead to a rip or cut in the heart muscle.Blood leaking through the heart valve where the ICD lead is placed.Bleeding around the heart, which can be life-threatening.Possible risks of implantable cardiac defibrillators (ICDs) or ICD surgery may include: A genetic heart condition that increases the risk of dangerously fast heart rhythms, such as some types of long QT syndrome.A history of coronary artery disease and a heart attack that has weakened the heart.Fainting is one of the symptoms.Īn ICD also may be recommended if you survived cardiac arrest or if you have: Your heart doctor may recommend an ICD if you have symptoms of an irregular heart rhythm called sustained ventricular tachycardia. An ICD lowers the risk of sudden death from cardiac arrest more than medicine alone. The devices are increasingly used in people at high risk of sudden cardiac arrest. It helps when there is a sudden loss of all heart activity, a condition called cardiac arrest.Īn ICD is the main treatment for anyone who has survived cardiac arrest. The device connects to a sensor, called an electrode, which runs along the breastbone.Īn ICD constantly checks for irregular heartbeats and instantly tries to correct them. A doctor places the S-ICD device under the skin at the side of the chest below the armpit. Subcutaneous implantable cardioverter-defibrillator (S-ICD)Ī subcutaneous implantable cardioverter-defibrillator (S-ICD) is a less invasive alternative to a traditional ICD.
