What are Defibrillators? Blog Image

Overview:

According to new research, defibrillators are used in only one out of every ten cardiac arrests where life saving devices are available.

About Defibrillators:

  • Defibrillators are devices that send an electric pulse or shock to the heart to restore a normal heartbeat.
  • They are used to prevent or correct an arrhythmia, an uneven heartbeat that is too slow or too fast. 
  • If the heart suddenly stops, defibrillators can also help it beat again. 
  • There are three types of defibrillators: AEDs, ICDs, and WCDs.
    • Automated External Defibrillators (AED):
      • An AED is a lightweight, battery-operated, portable device that checks the heart’s rhythm and sends a shock to the heart to restore normal rhythm.
      • The device is used to help people having cardiac arrest.
    • Implantable Cardioverter Defibrillators (ICDs):
      • ICDs are placed through surgery in the chest or stomach area, where the device can check for arrhythmias.
      • Arrhythmias can interrupt the flow of blood from your heart to the rest of your body or cause your heart to stop.
      • The ICD sends a shock to restore a normal heart rhythm.
    • Wearable Cardioverter Defibrillators (WCDs):
      • WCDs have sensors that attach to the skin.
      • They are connected by wires to a unit that checks your heart’s rhythm and delivers shocks when needed.
      • Like an ICD, the WCD can deliver low- and high-energy shocks. The device has a belt attached to a vest that is worn under your clothes.
  • Your provider fits the device to your size. It is programmed to detect a specific heart rhythm.

 


Q1) What is an arrhythmia?

An arrhythmia is a heart rhythm that isn’t normal. Your heart may be beating too fast when you’re at rest or just not beating in a regular pattern, for example. Arrhythmias range from harmless to serious, with symptoms and without. There are many options to treat arrhythmias, but some don’t need them.
