Abstract
In various method embodiments for classifying an arrhythmia, a characteristic of a ventricle is sensed before delivering a diagnostic neural stimulation. The diagnostic neural stimulation is delivered, and the characteristic of the ventricle is sensed while delivering the diagnostic neural stimulation. The sensed characteristic of the ventricle before and during the diagnostic neural stimulation is used to classify the arrhythmia as either a supraventricular tachyarrhythmia (SVT) or a ventricular tachycardia (VT). According to various embodiments, the characteristic of the ventricle is ventricular rate, similarity values of sensed ventricular morphology to a normal sinus rhythm (NSR), or ventricular hemodynamics. Various embodiments use ventricular rate regularity before and during the diagnostic neural stimulation to classify an SVT as atrial fibrillation (AF) or as another SVT.
