A LifeVest works by continuously monitoring your heart rhythm and delivering a treatment shock if a life-threatening rapid heartbeat is detected. Here's a more detailed explanation:
How a LifeVest Detects and Responds to Arrhythmias
The LifeVest is designed to be worn externally and continuously monitors a patient's heart. Here's a breakdown of its function:
- Detection: The LifeVest constantly analyzes your heart rhythm. When it detects an abnormal and dangerous heart rhythm, specifically a life-threatening rapid heartbeat, it triggers the next stage.
- Treatment: Once a life-threatening rhythm is detected, the LifeVest automatically delivers an electrical shock to the heart. This shock is designed to restore your heart to its normal, healthy rhythm.
The Treatment Process
The entire process, from the initial detection to the delivery of a shock, happens very quickly. According to the information provided, this whole process typically occurs in about one minute.
Here’s a simple way to visualize it:
| Step | Description | Timeline |
|---|---|---|
| Monitoring | LifeVest continuously monitors heart rhythms. | Constant |
| Detection | Detects a life-threatening rapid heartbeat. | Immediate |
| Treatment Shock | Delivers a therapeutic electrical shock to restore the heart rhythm. | Approximately 1 minute after detection |
Key Features
- Automatic Operation: The LifeVest operates automatically, requiring no intervention from the wearer or bystanders. This automatic function is crucial during a medical emergency.
- External Use: Unlike implanted devices, the LifeVest is worn externally, making it a non-invasive option. This means it does not require surgery to be used.
- Rapid Response: The fast response time is critical, ensuring that the heart receives treatment as quickly as possible during a life-threatening event.
Summary
In essence, the LifeVest acts as an external defibrillator, continually watching your heart for dangerous arrhythmias, and if needed, it delivers a life-saving shock within approximately one minute.
