| EST | electric shock threshold; electroshock therapy; endometrial sinus tumor; endoscopic sphincterectomy;... |
| ETL | echo train length; expiratory threshold load |
| FFT | fast Fourier transform; flicker fusion test or threshold |

| transmission threshold | <epidemiology> Occurs for a parasite when the basic reproductive rate Ro is equal to 1. Below this threshold level the disease is unable to maintain itself within the host population. Typically, for directly transmitted parasites there is a transmission threshold for the host population size. (05 Dec 1998) |
