As a domain expert in cardiology, I can provide you with information on defibrillation rhythms. Defibrillation is a medical procedure that applies an electric shock to the heart to restore a normal heart rhythm in patients experiencing certain life-threatening arrhythmias, such as ventricular fibrillation (VF) or pulseless ventricular tachycardia (VTach). Defibrillators are designed to recognize and respond to specific rhythms that are potentially responsive to defibrillation. Here are the key rhythms that can be defibrillated: 1. Ventricular Fibrillation (VF): A chaotic heart rhythm that causes the heart to quiver ineffectively, not pumping blood. 2. **Pulseless Ventricular Tachycardia (VTach)**: A rapid heart rhythm that can also prevent effective blood circulation without a detectable pulse. Automated External Defibrillators (AEDs) are programmed to analyze the patient's heart rhythm and will only deliver a shock if it detects one of these shockable rhythms. Non-shockable rhythms, such as asystole or pulseless electrical activity (PEA), will not receive a shock from an AED, as defibrillation is not effective for these conditions. It's important to note that the decision to defibrillate should be made quickly, as the chances of survival decrease significantly with each passing minute without treatment. read more >>

Description. Defibrillation - is the treatment for immediately life-threatening arrhythmias with which the patient does not have a pulse, ie ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT). Cardioversion - is any process that aims to convert an arrhythmia back to sinus rhythm.read more >>
