This is referred to as isolated systolic hypertension or isolated diastolic hypertension.

When we're gearing up to do something hard, systolic blood pressure goes up in anticipation of the performance.

当我们准备做一些困难的事情时，压会因为预期的表现而升高。

Typically, both systolic and diastolic pressures tend to climb or fall together, but that's not always the case.

一般来说，压和舒张压同时上升或者下降的，但也并不总这样。

Elevated systolic blood pressure is considered between 120 and 129 mmHg and less than 80 mmHg on the diastolic side.

期血压升高应该在120到129mmHg之间，舒张期血压则应该在小于80mmHg的区间内。

Sometimes, you can have systolic or diastolic hypertension, when one number is normal and the other is really high.
