So if we go 1 standard deviation to the right, that is going to be 1.

所以如果我们向右移动 1 个标准偏差，那就是 1。

That right there is the standard deviation to the right, that's the standard deviation to the left.

右边是右边的标准差，左边是标准差。

For example, in left ventricular hypertrophy the axis is skewed further left; while right ventricular hypertrophy results in a deviation to the right.

例如，左心室肥厚时，心电轴进一步向左倾斜；而右心室肥厚导致向右偏移。

So the empirical rule tells us that this middle area between 1 standard deviation to the left and 1 standard deviation to the right, that right there is 68%.

所以经验法则告诉我们，这个中间区域在左边 1 个标准差和右边 1 个标准差之间，右边有 68%。
