Narrative:
During an emergency situation I was vectoring a lifeguard for a class D airport adjacent to a class C airport. The lifeguard said that he could take a small delay for the emergency aircraft. I anticipated the descent of a B737 going into the class C also. After working out the sequence with the emergency and the lifeguard I recognized that the B737 had descended more rapidly than anticipated and went thru the 4;700 ft MVA. The next lowest MVA is 3;000 and I did not say anything because he would be in the MVA in less then a mile. During the complex situation I should not have anticipated the descent of the aircraft.
