== Abnormal Impulse Formation==
The mechanism of abnormal automaticity (in contrast to normal automaticity) is similar to the normal automaticity of sinus node cells. Abnormal automaticity can be caused by changes in the cell ion channel characteristics due to drugs or changes in the electrotonic environment. Abnormal automaticity can result from an increase of normal automaticity in non-sinus node cells or a truly abnormal automaticity in cells that don't exhibit a phase 4 diastolic depolarization.
