How does the ICD recognize the type of arrhythmia? Tachyarrhythmia discrimination in modern transvenous cardioverter defibrillators

Modern cardioverter defibrillators apply different discrimination algorithms to differentiate between supraventricular arrhythmias and malignant ventricular arrhythmias, leading to a decrease in the rate of inappropriate ICD therapies. The two main groups of discrimination algorithms are single-cham...
