This paper describe a monitoring model for intelligent systems in the assessment tasks of patient´s critical states. The model was designed according to temporal abstraction dimensions and state interpretation levels, particularly the monitored physiological state. Monitoring arrhythmias was used as the reference case for model development. This model is based on the Smith-Waterman algorithm, with a modified substitution matrix. It was developed for the state space assessment model, for said application. Matrix modification was oriented for giving more influence to the principal state for the temporal pattern represented. The performance of the state interpretation model was similar than other models reported in the literature. The state space assessment model allow to get extra temporal information about a possible evolution, not previously available in classic monitors.
