  • Professor Zach Whinnet is an exceptional doctor with a very good reputation. I was referred to him recently as I had Atrial Fibrillation and other challenges with the heart function which needed attention. Within six days, Zach performed an ablation which was very successful and my heart returned to its normal rhythm. As a result of the procedure, I am well on the road to recovery. Zach is extremely grounded, very personable and highly talented. I was very fortunate to be treated by him.
