1.	_________ is based on analyzing the shape of the QRS complexes and separating beats into groups or clusters.(a) Timing classification(b) Morphology characterization(c) Beat labeling(d) Noise detectionThis question was posed to me at a job interview.The origin of the question is Phonocardiography (PCG) in section Biomedical Recorders of Biomedical Instrumentation
Answer» Correct answer is (B) Morphology characterization To EXPLAIN I would say: Morphology characterization is based on analyzing the shape of the QRS complexes and separating beats into GROUPS or clusters of similar morphology. Most algorithms for real time arrhythmia analysis MAINTAIN no more than 10-20 clusters at a time, order to limit the AMOUNT of computation needed to assign a QRS complex to a cluster.
