Exhibit 99.1


Forward Looking Statements
2
Statements in this presentation that are not purely historical are forward-looking statements within the 
meaning of the Private Securities Litigation Reform Act of 1995 including, but not limited to, statements 
about existing and potential partnerships and distribution arrangements that Cambridge Heart, Inc. (the
“Company”) is, or may become party to, statements about the Company’s expected launch of the MTWA 
Module by Cardiac Sciences Corporation, future operating results, the Company’s belief that the Company’s
existing cash resources are sufficient to fund operations through March 31, 2011, the Company’s 
expectations and estimates regarding MTWA Module metrics (i.e., MTWA Module and sensor sales prices, 
gross margins and sensor utilization), and product development plans.  These forward-looking statements 
are based on current expectations and assumptions that are subject to risks and uncertainties.  Actual 
results could differ materially from the results expressed or implied in these forward-looking statements. 
Material deviations from our current operating plan, including a delay in launching the MTWA Module, lower 
than expected sales of the MTWA Module, lower than expected sales of the Heartwave II System, lower than
expected sales prices or gross margins for the MTWA Module and lower than expected sensor utilization by
purchasers of the MTWA Module, may cause or contribute to such differences.  Other factors that may cause 
or contributed to such differences include failure to achieve broad market acceptance of the Company’s 
MTWA technology, failure of our sales and marketing organization or partners to market our products 
effectively, inability to hire and retain qualified clinical applications specialists in the Company's target 
markets, failure to obtain or maintain adequate levels of first-party reimbursement for use of the Company's
MTWA test, customer delays in making final buying decisions, decreased demand for the Company's 
products, failure to obtain funding necessary to develop or enhance our technology, adverse results in future
clinical studies of our technology, failure to obtain or maintain patent protection for our technology and 
overall economic and market conditions.  Many of these factors are more fully discussed, as are other 
factors, in Part I, Item 1A. “Risk Factors” of the Company’s Annual Report on Form 10 K for the fiscal year 
ended December 31, 2009, which is on file with the SEC and available at www.EDGAR.com.  In addition, any
forward-looking statements represent our estimates only as of today and should not be relied upon as
representing our estimates as of any subsequent date.  While the Company may elect to update forward-
looking statements at some point in the future, the Company specifically disclaims any obligation to do so
except as may be legally necessary, even if the Company’s estimates should change.

Class IIa
Guideline
American College of Cardiology/American Heart Assoc./European Society of
Cardiology 2006 Guideline for Management of Patients With Ventricular
Arrhythmias and the Prevention of Sudden Cardiac Death  (Developed in
collaboration with the HRS and EHRA)
Class IIa
It
is
reasonable
to
use
T-Wave
Alternans
for
improving
the
diagnosis
and
risk
stratification
of
patients with ventricular arrhythmias or who are
at risk for developing life-threatening ventricular
arrhythmias. (Level of Evidence: A)
10


CMS National Coverage
“CMS (Medicare) has determined that there is
sufficient evidence to conclude that Microvolt T-
wave Alternans (MTWA) diagnostic testing is
reasonable and necessary
for the evaluation of
patients at risk of sudden cardiac death, only
when the spectral analytic method*
is
used, and CMS is issuing the following national
coverage determination (NCD) for this
indication.”
93025 (3/21/2006)
* Cambridge Heart US Patent # 6,735,466 granted May 2004

Medicare Reimbursement
National Average: $196
Reimbursement is limited if MTWA is performed at
the same time as standard stress, stress echo or
nuclear stress testing
Negatively impacts physician’s ability to integrate
MTWA testing for high-risk cardiac
patients
CHI has requested that CMS remove the current
limitations
A positive outcome would provide full reimbursement 
for both stress and MTWA tests during the same
patient visit
12


Private Coverage
Private payers followed CMS:
Aetna, Cigna, Humana
HCSC, BC/BS of NY, Horizon (NJ), Care First, MI, IA, SD,
MN, KS, Wellmark, Premera, BCBS of AZ
Harvard Pilgirim
Regionals: GHI, Tufts, Med. Mutual of Ohio, Health Net
Coverage typically for ICD indicated population
Other private payers in progress

Initial Market Positioning
14
Historical clinical positioning and marketing
linked MTWA testing to ICD therapy
That positioning limited the market opportunity
and perception of MTWA testing
300,000 to 1 million primary prevention patients
Focus on EP community and testing of border line patients
Entanglement in clinical disagreements on ICD therapy
Additional Challenges
Relatively expensive, stand-alone MTWA equipment platform
Single product offering and inability to offer a complete
“solution”;
Practice integration issues
Lack of distribution
Economic environment for medical capital equipment


New Strategic Direction
Position MTWA as a tool to “assess
and “manage
an individual’s risk of SCA in the high risk
population
Make MTWA more accessible to the high risk
population
Develop multiple product embodiments and industry partnerships
Create an attractive physician ROI
Simplify practice integration
Re-organize resources on the primary corporate
value driver (i.e. sensor utilization)
