Mobitz type 1 heart block is a subtype of second degree heart block. The electrical signals that control the heart beat become disrupted. Learn more here.

Sinoatrial node: As mentioned before, the sinoatrial node is your heart’s natural pacemaker. How fast or slow your sinoatrial node sends your heart the signal to contract depends on your ...
