Mobitz type 1 heart block: Causes, symptoms, and treatment

WebHeart block, also called AV block, is when the electrical signal that controls your heartbeat is partially or completely blocked. This makes your heart beat slowly or skip beats and your heart can’t pump blood effectively. Symptoms include dizziness, fainting, tiredness and shortness of breath. Pacemaker implantation is a common treatment. WebIt is denoted by counting the number of P-waves before each block. If every third P-wave is blocked, then there is 3-to-2 block (which is the most common). If every fourth P-wave is blocked, it is classified as 4-to-3 …
