Atrioventricular block, complete.

My mother is a patient of high bp  Yesterday in the evening , all of a sudden she started feeling dizzy and as if there is no energy left in the body. Quickly checked the bp . It was 142/79 and pulse being 88 After 10 minutes we again check because in the oximeter the pulse was fluctuating alot So checked the bp and pulse again with BP machine. BP was 120/70 and pulse was 45 And it was going up an down everytime we checked Then my mum felt like puking. Then after vomiting she felt that she is now better . Bu then I again checked the pulse it was still low. 42-45 So we went for ecg at the nearby hospital they checked and said there is blockage and asked us to admit her in metro hospital Faridabad. She is now there and several tests were done. Angiography reports are here. I am attaching them as well I just want an opinion. As the doctors are saying in angiography everything is normal but then they are also saying to have the pacemaker. So want a second opinion Pls suggest
