Seventeen in-patients with pregnancy-induced hypertension (PIH) in the last trimester of pregnancy underwent an exercise stress test. The mean exercise intensity achieved was 66% (55-77%) of submaximal exercise. The mean maternal heart rate rose significantly from a mean of 89 beats per minute (64-110 bpm) to a mean of 144 bpm (120-168 bpm) after exercise. ⋯ Subsequently it rose significantly to peak at 20 minutes of recovery. No evidence of ill effect from the exercise test was noted on any of the mothers or their fetuses. All pregnancies resulted in a good outcome.
