Understanding Defibrillators: The Life-Saving Device Defibrillators are critical medical devices that can save lives by restoring a normal heart rhythm in people experiencing sudden cardiac arrest (SCA). These devices work by delivering a controlled electrical shock to the heart , which can restart it and allow it to resume its normal rhythm. In this blog, we will explore the different types of defibrillators, how they work, and why they are crucial in emergency situations. What is a Defibrillator? A defibrillator is a device used to deliver a shock to the heart in order to correct certain abnormal heart rhythms, most notably ventricular fibrillation (VF) and ventricular tachycardia (VT). These conditions cause the heart to beat irregularly and ineffectively, making it unable to pump blood to vital organs. This can lead to death if not treated within minutes. Defibrillators are designed to monitor the heart’s rhythm and, when necessary, provide an electric shock to restore ...
