(1) Physiology. The ability of tissue to spontaneously generate an electrical impulse and propagate an action potential. Automaticity is an inherent property of the normal SA node. (2) Devices.  The ability of a device to recognize the need for a change in values and to make these corresponding adjustments automatically.  An example of device automaticity is an increase in pacing rate based on sensor input.

The capacity of a cardiac cell to depolarize spontaneously.

The inherent property of myocardial cells to generate an electrical impulse by spontaneous depolarisation.

In GATT negotiations on dispute settlement procedures, refers to proposals to have reports of dispute panels automatically adopted by the GATT Council if no specific objections to adoption are raised (i.e. without requiring an affirmative decision by the disputing parties). Other proposals would give the country winning a GATT dispute an automatic right to withdraw concessions if, after a specified time, the defending party has neither complied with a panel's recommendations nor agreed to an acceptable timetable for compliance. GATT rules and procedures currently contain no time limits for implementation f panel reports, and implementation may be delayed indefinitely.

Automaticity is the ability to do things without occupying the mind with the low level details required. It is usually the result of learning, repetition, and practice.

The state that is achieved when an action has gone through the process of automatization.
