Time series derived from consecutive systolic (diastolic) blood pressure values.
.
Fig.1 Four seconds of systogram, SBP(t), diastogram, DBP(t), and Pulse Interval, PI(t), time series derived from a Finapres recording (upper panel).
Often these series are expressed as a function of the beats number, n, rather than as a function of time, t.
Fig.2. Systogram SBP(n), diastogram DBP(n) and pulse interval PI(n)
series as a function of n, the beat number, for the first 16 heart beats
of the same Finapres recording of fig.1. In this case (see fig.1, upper
panel), DBP(n) is the value of diastolic pressure following SBP(n), and
PI(n) is given by the difference between the times of occurrence of SBP(n+1)
and SBP(n).
