A wearable cardioverter defibrillator (WCD) is a non-invasive, external device for patients at risk of sudden cardiac arrest (SCA). [1] It allows physicians time to assess their patient's arrhythmic risk and see if their ejection fraction improves before determining the next steps in patient care.
This is the story of the LifeVest®, the only FDA-approved wearable cardioverter defibrillator (WCD) indicated to reduce the risk of sudden cardiac death (SCD) in patients with reduced left ventricular ejection fraction (LVEF) who have suffered an acute myocardial infarction (AMI).
The recent emergence of the wearable cardioverter-defibrillator provides a new prophylactic strategy for patients who are at significant risk for VT/VF but are not immediate candidates for ICD implantation.
Since SCD risk may sometimes be transient, a wearable cardioverter defibrillator (WCD) has been developed and approved for clinical use in 2001 as a proposed solution for short-term risk mitigation in select populations at high risk of SCD.
A LifeVest is a wearable defibrillator that can stop an abnormal heart rhythm without anyone’s help. People at risk of sudden cardiac arrest wear it while waiting for a more permanent solution. They wear it under their clothes and remove it only for bathing.
The LifeVest ® wearable cardioverter defibrillator (WCD) is designed to protect patients at risk of sudden cardiac death (SCD), when a patient’s condition is changing and permanent SCD risk has not been established.
The LifeVest ® wearable cardioverter defibrillator (WCD) is worn by patients at risk of sudden cardiac death (SCD). A defibrillator is a device that is used to control dangerously fast heart rhythms by applying an electrical shock to the heart.
LifeVest is a wearable defibrillator that, unlike an implantable cardioverter defibrillator (ICD), is worn outside the body rather than implanted in the chest. The device is designed to alert a patient prior to delivering a treatment shock, and thus allows a conscious patient to delay the treatment.
What is a wearable cardioverter defibrillator (WCD)? A WCD is a vest with a small monitor. The vest contains electrodes, or pads, that can shock your heart if the monitor detects a life-threatening arrhythmia.
The implantable cardioverter-defibrillator (ICD) has been shown to improve survival from sudden cardiac arrest and to improve overall survival in several populations at high risk for sudden cardiac death (SCD).
