Gaussian Modelling Characteristics of Peripheral Arterial Pulse: Difference between Measurements from the Three Trimesters of Healthy Pregnancy

Table 1

Means ± SDs of heart rate and blood pressures measured at the three trimesters of normal pregnancy.

Trimesters	HR (beats/min)	SBP (mmHg)	DBP (mmHg)
First	85 ± 12	115 ± 10	73 ± 9
Second	93 ± 11	111 ± 8	70 ± 7
Third	94 ± 13	109 ± 11	69 ± 9

in comparison with the first trimester.
