Fuzzy Linguistic Protoforms to Summarize Heart Rate Streams of Patients with Ischemic Heart Disease

Figure 5

Example of the protoforms in real rehabilitation sessions. (a) A session with predominance of adequate adherence and some high rates. (b) The degree of the term adequate is represented by the dotted line; the degree of the protoform at least half of the time the HR is adequate for around 25-50 minutes is represented by the thick line. The aggregated degrees maximum and amplitude are shown in the bottom. (c) The degree of the term high is represented by the dotted line; the degree of the protoform most of the time the HR is high for around 1-3 minutes is represented by the thick line. The aggregated degrees maximum and amplitude are shown in the bottom. (d) A session with predominance of low adherence and some high rates. (e) The degree of the term low is represented by the dotted line; the degree of the protoform most of the time the HR is low for around 15-25 minutes is represented by the thick line. The aggregated degrees maximum and amplitude are shown in the bottom. (f) The degrees of the terms high and low are represented by the dotted line in yellow and blue, respectively; the degree of the protoform part of the time the HR is high in the last 2 minutes part of the time the HR was low around 1-3 minutes ago is represented by the thick line. The aggregated degrees maximum and amplitude are shown in the bottom.
