Twelve cases (63.2%) showed conduction blocks, including right bundle branch block (RBBB) in three cases, complete atrioventricular block (AVB
) in three cases, complete AVB
with RBBB in three cases, left anterior fascicular block (LAFB) in one case, RBBB with LAFB in one case, and Mobitz type II 2[sup]nd degree AVB
with RBBB in one case.
We follow the CE methodology in estimating a likelihood of receipt for each income source for AVBs. (14) The dependent variable equals 1 if the consumer unit received income from a given source and 0 otherwise.
(29) AVBs are excluded from this exercise because they have no income to be imputed.
High-[O.sub.3] exposure caused a significant increase in the number of APBs (2,200%; p < 0.05), SABs (32,600%; p < 0.05), and Mobitz type 1 second-degree AVBs
(1,300%; p < 0.05) during exposure relative to preexposure baseline values (Table 1).
Upon arriving at a forward location, the AVB
would beach, lower its ramp, and disgorge two-and-one-half-ton trucks towing the service trailers to the forward base, carrying tent-age and supplies for a cantonment area.
