The sinus node normally initiates activation of the heart because it has the fastest intrinsic rate of automaticity. Frequently, for a variety of reasons, premature beats can arise from atrial tissue, junctional tissue, or ventricular tissue. The most common cellular mechanism for these premature beats is increased automaticity.
