1. opposition to or hampering of some activity.
2. impairment of cardiac impulse conduction due to refractoriness of the tissue; the refractoriness is a physiological response to passage of a preceding impulse.
3. a premature contact point on the occlusal surface of the teeth.
electromagnetic interference electrical signals of nonphysiological origin that may affect pacemaker function; they can either inappropriately inhibit pacemaker output or trigger unnecessary pulses. Pacemakers with bipolar leads are less sensitive to this.
occlusal i's areas of interference on teeth that hamper proper occlusion and smooth, gliding, harmonious jaw movements.
