interference

 [in″ter-fēr´ens]
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.

in·ter·fer·ence

(in'tĕr-fēr'ens),
1. The coming together of waves in various media in such a way that the crests of one series correspond to the hollows of the other, the two thus neutralizing each other; or so that the crests of the two series correspond, thus increasing the excursions of the waves.
2. Collision within the myocardium of two waves of excitation at the junction of territories controlled by each, as is seen in atrioventricular (AV) dissociation.
3. Also in AV dissociation, the disturbance of the regular rhythm of the ventricles by a conducted impulse from the atria, for example, by a ventricular capture (interference beat).
4. The condition in which infection of a cell by one virus prevents superinfection by another virus, or in which superinfection prevents effects that would result from infection by either virus alone, even though both viruses persist.
[inter- + L. ferio, to strike]

interference

Modification of light intensity arising from the joint effects of two or more coherent trains of light waves superimposed at the same point in space and arriving at the same instant. The waves may either reinforce each other, being in phase (constructive interference) or cancel each other, being out of phase (destructive interference). See coherent sources; Young's experiment; holography; phase; optical coherence tomography.

Patient discussion about interference

Q. Does omega-3 interfere with diabetes treatment? I’m a 55 years old man, and was diagnosed with diabetes mellitus, along with high lipid levels several years ago. A couple of months ago I read that omega-3 can protect your heart and brain, so I started to take omega-3 pills every day. Yesterday I read in some website that omega-3 can interfere with the drugs I take to treat my diabetes- Is that right?

A. Omega-3 doesn’t influence the treatment of your diabetes, and since you have high lipids, that can contribute to some of the damage diabetes does to your body, omega-3, that may lower the lipid level in your may actually help you treat yourself overall better. However - consult your doctor. Better be safe than sorry...

Q. Will my bipolar meds (lamictal and depakote) interfere with my birth control pills? We have been married for the past 12 yrs but we don’t have a child because I am paranoid of delivery. But it doesn’t affect our intimacy. I am using birth control pills for the past few years and I could rely on it. Now the new problem is that I was recently diagnosed as bipolar-II. The Doctor prescribed some medicines for me. Will my bipolar meds (Lamictal and Depakote) interfere with my birth control pills?

A. there are interactions, birth control pills can reduce the amount of Lamictal in the blood, causing it to be less affective. the drug level in plasma should be monitored. ask both your therapists about it- your gynecologist and the psychiatrist.

It is aware that since WBPFM interfering signals have significant concentrated energy distribution and periodicity in the time-frequency domain, there are a few TF points affected by the interferences. For the convenience of expression, an analysis is carried out by taking two linear frequency-modulated continuous wave (LFMCW) interfering signal as an example, and their spectrogram is shown in Figure 1, where [f.sub.c] and B are the carrier frequency and bandwidth, respectively; [mathematical expression not reproducible], denotes the frequency bins; [T.sub.c] and l represent the integer multiple of two modulation period of the two LFMCW interfering signals and a positive integer, respectively; and [mathematical expression not reproducible] is the number of signal data in time domain.
