Is the damage to the organs caused by hypertension offset by a slower heartbeat?

As far as I understand, hypertension is dangerous primarily because of the slow damage to the organs which have to sustain the elevated pressure. But would this damage be smaller if the normal heartbeat was slower than the average? For example, pressure of 140/90 with the heartbeat of 50 would be less dangerous than pressure of 140/90 with the heartbeat of 70? Right?
