An Implantable Cardioverter Defibrillator (ICD) is a device used to treat arrhythmias, particularly ventricular fibrillation and ventricular tachycardia, which can be life-threatening if not corrected promptly. Here's an overview.
Arrhythmias may present with symptoms such as palpitations, dizziness, fainting, chest pain, or shortness of breath.
In severe cases, sudden cardiac arrest may occur, leading to loss of consciousness and death if not treated promptly.
If a patient is diagnosed with a high-risk arrhythmia, an ICD may be recommended by a cardiologist. The device is surgically implanted under the skin and connected to the heart to monitor and deliver electrical shocks to restore normal heart rhythm if dangerous arrhythmias occur.
Treatment plans may also include medications to control heart rhythm or reduce the risk of arrhythmias, lifestyle changes, and cardiac rehabilitation.
Diagnosis involves various tests, including an electrocardiogram (ECG/EKG) to detect abnormal heart rhythms, Holter monitoring for continuous ECG recording over 24-48 hours, or event monitors for longer-term monitoring.
Additional tests such as echocardiography, stress tests, or electrophysiology studies may be performed to assess heart function and identify the underlying cause of the arrhythmia.
