Cardiovascular devices help monitor irregular heartbeats in people with certain heart disorders and heart failure.
FREMONT, CA: Cardiac implantable electronic devices, such as pacemakers, implantable cardioverter-defibrillator (ICD), biventricular pacemakers, and cardiac loop recorders, are developed help manage or monitor irregular heartbeats in people with some heart rhythm disorders and heart failure. After the device is placed, it gathers information about the heart rhythm. This information is transmitted wirelessly to the cardiac device team, either automatically, through prescheduled transmissions, or manually, when one notices symptoms. Remote monitoring enables the review of the heart's electrical activity as required without a doctor's visit.
Implantable Cardioverter Defibrillators
People with heart diseases, heart failure, and particular genetic arrhythmias are often at risk of life-threatening, quick, irregular heartbeats called ventricular arrhythmias. These people may require an ICD, which offers an electric shock to restore a normal heart rhythm. An ICD is recommended for people with ventricular arrhythmias who have not responded to treatments like catheter ablation or medical therapy.
There are two kinds of pacemakers. The conventional model is placed under the skin and connects to the heart through electronic leads. A smaller pacemaker is placed inside the heart and does not need transvenous leads. Pacemakers are leveraged to handle bradycardia, a condition that causes the heart to beat too slowly—less than 60 beats per minute. The pacemaker generates electrical pulses that keep the heart beating at a normal rate.
A biventricular pacemaker performs like a conventional pacemaker. Still, it leverages the third wire to send electrical impulses to the heart to the heart's left lower chambers or ventricles' contractions. Also named a cardiac resynchronization device, a biventricular pacemaker is deployed when medications don't relieve heart failure symptoms. A resynchronization device manages the contractions of the left ventricle.
Implantable Cardiac Loop Recorders
The cardiac electrophysiologist may recommend implanting a wireless cardiac monitor called a loop recorder. This device continuously records data about the heart's rhythm for up to three years. Smaller than the size of a AA battery, the implantable cardiac loop recorder is inserted below the upper chest's skin to record information about the heart's electrical activity, much like an electrocardiogram or EKG. It is leveraged to diagnose or identify the source of an arrhythmia.
