Sinoatrial conduction

Sinoventricular conduction, also known as sinoventricular rhythm, diffuse complete atrial muscle conduction block, or hyperkalemic diffuse complete atrial muscle conduction block combined with high-grade intraventricular block. Elevated blood potassium appears with muscle weakness, and even paralysis. It usually appears more in the lower limbs, then extends upward along the trunk to the upper limbs, and the respiratory muscles are involved only in very rare cases.
