In 1963, Microwave Communications, Inc., the predecessor corporation to MCI,^[11]requested permission from the Federal Communications Commission ("FCC") to construct and operate a long distance telephone system between Chicago and St. Louis. The proposed system consisted of a terminal in each city and microwave radio relay towers connecting the terminals. Through this system, MCI intended to provide long distance, private line telephone service to business and industrial subscribers whose needs justified the exclusive or semi-exclusive use of a long distance telephone line. MCI also sought interconnections from its terminals to ordinary local telephone facilities, principally telephone wires running in conduits beneath the street. These interconnections were essential to MCI's ability to do business, since they provided the telephone or computer linkage between MCI's terminals and its individual customers in each city.

Q2

Why does a patient with congestive cardiac failure have excessive

sweating?

Q3

What is cardiac asthma?

Q4

In a book, under the title 'Heart failure' I have seen the following phrase:

'Cardiac failure occurs when, despite normal venous pressures, the heart

is unable to maintain sufficient cardiac output...'. Is it correct to say

'normal venous pressures'? All protective and compensatory mechanisms

raise the venous pressure to maintain a sufficient cardiac output -

according to Frank-Starling law - and this is the case in heart failure, so

I think it was meant to say: '...despite high venous pressures...'.

Q5

I wanted to ask whether a third heart sound is present, or should be

present, in all cases of heart failure, whatever the underlying cause.

Q6

Why can left heart failure lead to right heart failure but not vice versa?

What is the physiology involved in this transition?

Q7

Could you explain the fetal gene program, activated in heart failure?

Q8
