WebParoxysmal high-grade second-degree and persistent third-degree atrioventricular block in cats Outcome in cats with AVB was variable, although most had good medium- to long-term survival. Cardiac death occurred in a minority of cats. Pacemaker implantation was effective in relieving clinical signs. WebSecond-degree AV block is a form of "incomplete" heart block, in which some, but not all, atrial beats are blocked before reaching the ventricles. Mobitz type II second-degree block is an old term, which refers to periodic atrioventricular block with constant PR intervals in the conducted beats.
