Left anterior fascicular block is one of the commonest causes of left axis deviation and has specific ECG criteria for its diagnosis. There's less contribution to the electrical vector from the left so it deviates to the right. In other words, when the person breathes in, their heart rate increases, and when they breathe out, the rate decreases. It occurs when a persons heart rate relates to their breathing cycle.
