This is brutal. On top of it, the man was recovering from heart surgery.

Inquisitr – According to the London Telegraph, “The video shows [the doctor] identified as Andrei Votyakov talking animatedly to the patient, who wears an oxygen mask and has his arms and legs fastened to the bed. Mr. Votyakov then punches the patient in the face before bringing his fist down heavily on the victim’s chest.”

Dr. Votyakov claimed he was exhausted after working a 36-hour shift and lost his temper when the patient started peppering him with insults. Sky News offers an explanation from the anesthesiologist: “As soon as I came into the room with my team he started to call me various derogative names. And I just got blown away by it. We had spent so much time with his very complicated case to help him recover and he said not a single word of gratitude. And then the chronic tiredness added to it. I got carried away, and I punched him several times.”
