Before DAVIS, DUHÉ, and PARKER, Circuit Judges.

PER CURIAM:*

     Ronald Bourg was employed by Halliburton Energy Services

(“Employer”)   as   a    cementer/mixer.       On   May   24,   1993,   while

performing his duties on an offshore oil rig, Bourg experienced

chest pains, shortness of breath, and dizziness.           He was admitted

to the hospital where he was treated for congestive heart failure.

Thereafter, Bourg was diagnosed with cardiomyopathy, a disease of

the heart muscle.        He then sought benefits under the Longshore and

Harbor Workers’ Compensation Act (“LHWCA”), 33 U.S.C. § 901, et

seq. (“LHWCA”). The Administrative Law Judge (“ALJ”) awarded Bourg

temporary total disability compensation from May 24, 1993, until

December 9, 1996, and permanent total disability compensation

thereafter.      The Benefits Review Board (“BRB”) affirmed the award.

Employer petitions this Court for review of the decision of the

BRB.

       Under the LHWCA, the BRB must treat the ALJ’s findings of fact

as conclusive if supported by substantial evidence on the record as

a whole.       Crum v. General Adjustment Bureau, 738 F.2d 474, 477

(D.C. Cir. 1984).        When reviewing the BRB’s decision, this Court

must determine whether the BRB adhered to the applicable scope of

review; whether the BRB committed any errors of law; and whether

the ALJ’s findings are supported by substantial evidence on the

record as a whole.        Id.

       Employer first contends that the ALJ and the BRB erred in

finding that Employer did not rebut the presumption under Section

20(a), 33 U.S.C. § 920(a).            Under Section 20(a), a claimant is

entitled    to    a    presumption   that   his   claim   comes      within    the

provisions of the LHWCA if he establishes: (1) that he suffered an

injury   and     (2)   that   the   accident   occurred   in   the    course    of

employment or that conditions existed at work that could have

caused the harm.         Gooden v. Director, OWCP, 135 F.3d 1066, 1068

(5th Cir. 1998).        Upon invocation of the presumption, the burden

shifts to the employer to rebut the presumption with substantial

evidence that the claimant’s condition was not caused or aggravated


                                        2
by his employment.    Id.   If the employer rebuts the presumption,

then the ALJ must weigh all the evidence of record to resolve the

causation issue.    Id.

     The ALJ and the BRB correctly found that Bourg established a

prima facie case and was thus entitled to the Section 20(a)

presumption.    Bourg established the existence of a harm by showing

that after undergoing acts of physical exertion while working for

Employer, he experienced shortness of breath, chest pains, and

dizziness such that he required admission to the hospital where he

was treated for congestive heart failure. Employer’s argument that

Bourg did not establish that he sustained an injury because he only

suffered symptoms of his preexisting cardiomyopathy is without

merit.    It is well-recognized that an aggravation of a preexisting

condition may constitute a compensable injury.    See Crum, 738 F.2d

at 478.

     The evidence of record, specifically the testimony of Dr.

Richard Abben and Dr. Thomas Giles, shows that although Bourg’s

work did not cause his cardiomyopathy, his work for Employer

accelerated and aggravated his underlying heart condition causing

him to experience symptoms sooner than he otherwise would have.

Both Drs. Abben and Giles testified that Bourg’s work shortened the

“window of time” Bourg had before the symptoms began to manifest

themselves.     In light of this evidence, Bourg showed that he

suffered a harm arising out of his employment.

     The ALJ and the BRB were further correct in their findings

that Employer did not rebut the presumption by establishing through

substantial evidence that there was a lack of causal connection


                                  3
between the injury and the employment.               The evidence, as stated

above,   shows    that     although    Bourg’s     work   did     not    cause      his

underlying heart condition, his work did precipitate the onset of

his symptoms.       Employer offered no substantial evidence to the

contrary.

      Because we find that the ALJ’s and the BRB’s findings that

Employer failed to rebut the Section 20(a) presumption and that

therefore Bourg’s present medical condition is causally connected

to his employment, we find no error in the conclusion of both the

ALJ and the BRB that Bourg’s symptoms are a compensable injury

under the LHWCA.

      Employer next contends that any disability suffered by Bourg

after his discharge from the hospital on June 4, 1993, cannot be

attributed to Employer.           A review of the record, however, shows

that Bourg has undergone numerous hospitalizations for his heart

condition   since    the    incident    on   May   24,    1993,      including      the

implantation of defibrillators. As the BRB noted, it is clear that

if a claimant’s employment played a role in the manifestation of

his   disease,    the    entire    resultant     disability     is    compensable.

Strachan Shipping Co. v. Nash, 782 F.2d 513 (5th Cir. 1986);

Bludworth Shipyard, Inc. v. Lira, 700 F.2d 1046 (5th Cir. 1983).

As Bourg’s present medical condition is causally connected to his

employment with Employer, we find no error in the ALJ’s and Board’s

conclusion that Bourg is entitled to total disability benefits.

      For   the   foregoing       reasons,   the   decision     of      the   BRB    is

        After this appeal was submitted to this Court, the United
States Department of Labor sent a letter to the Court dated April
7, 1999, stating that in the event this Court affirms the BRB’s
affirmance of the ALJ’s award of permanent total disability
benefits commencing on December 10, 1996, the Director of the
Office of Worker’s Compensation Programs concedes to application of
section 8(f), and payment by the Special Fund, 33 U.S.C. § 908(f),
§ 944. The letter also stated that the payments by the Special
Fund would commence 104 weeks after December 10, 1996, the date on
which Bourg’s condition became permanent.
