Previous: MI Causing PC
Since the high LAP is an immediate
effect and low LVF has no max-exist clause, the time interval of
low LVF is the same as that of the high LAP.
- low LVF
(low LVF starting before now and
ending before now but not more than 24 hours before now)
This in turn is caused by the MI, which already is known to be true
over the time interval 
. Since effects can not precede
causes, this further constrains the low LVF and high LAP.
Low LVF has a definite begin time from the MI and the onset time of zero
for low LVF. It definitely continues until 5hr because it is not
intermittent nor is its maximum existence exceeded. In applying the new
time interval for high LAP to PC, there is another consideration. Since
there is another possible cause for PC (pneumonia) which is still
unknown, the beginning could still be prior to 6 hours ago. The latest
begin time can not be constrained further either since the onset can be
up to 6 hours. Thus, the time interval for PC remains as it was before.
The resulting hypothesis is shown in figure 5.
