Automated external defibrillators (AEDs) and implantable cardioverter defibrillators (ICDs) are used to treat life-threatening arrhythmias. AEDs and ICDs use shock advice algorithms to classify ECG tracings as shockable or non-shockable rhythms in clinical practice.

However, he suddenly developed a series of malignant ventricular arrhythmias. He required multiple defibrillations within a period of a few hours. Below are printouts of some of the arrhythmias recorded. This time, the arrhythmia did not spontaneously terminate — but rather degenerated to VFib, requiring defibrillation.

If VT is not treated, it can lead to cardiac arrest, which is when the heart stops beating. In fact, VT is the most common cause of sudden cardiac arrest. Patients may feel a fluttering in the chest, chest pain, shortness of breath and dizziness or lightheadedness as a result. Q: How is VT typically treated?
