Key result
The multiway sequential hypothesis testing algorithm discriminated ventricular tachycardia, supraventricular tachycardia, and normal sinus rhythm with a sensitivity of 0.95 and specificity of 0.97.

Structured PICO
Does the MSHT algorithm accurately and rapidly discriminate between VT, SVT, and NSR using endocardial recordings?
P
Population
30 patients providing endocardial atrial and ventricular recordings for the evaluation of 17 VT, 8 SVT, and 12 NSR episodes.
E
Exposure
Multiway sequential hypothesis testing (MSHT) algorithm for simultaneous discrimination of VT, SVT, and NSR
O
Outcome
Discrimination accuracy (sensitivity and specificity) and detection timesurrogate
The MSHT algorithm provides rapid and highly accurate discrimination between VT, SVT, and NSR, which could improve the diagnostic performance of automatic implantable cardioverter-defibrillators.
Cite This Study
Thakor et al. (2003) conducted an observational in Arrhythmias (Ventricular Tachycardia, Supraventricular Tachycardia, Normal Sinus Rhythm) (n=30). Multiway sequential hypothesis testing (MSHT) algorithm was evaluated on Simultaneous discrimination of VT, SVT, and NSR. The multiway sequential hypothesis testing algorithm discriminated ventricular tachycardia, supraventricular tachycardia, and normal sinus rhythm with a sensitivity of 0.95 and specificity of 0.97.
