         This Amendment No. 1 amends and restates in its entirety the Schedule
13D filed by the Reporting Persons (as defined herein) on May 13, 2002.

ITEM 1.  SECURITY AND ISSUER

         The class of equity securities to which this statement relates is the
shares of Common Stock, without par value (the "Shares"), of Quinton Cardiology
Systems, Inc. (formerly QIC Holding Corp.), a California corporation
("Quinton"). The principal executive office of Quinton is located at 3303 Monte
Villa Parkway, Bothell, Washington 98021.

ITEM 2.  IDENTITY AND BACKGROUND

         (a) This statement is being filed by Koninklijke Philips Electronics
N.V.("KPENV"), Philips Holding USA Inc. ("PHUSA") and Philips Electronics North
America Corporation ("PENAC" and, collectively with KPENV and PHUSA, the
"Reporting Persons"). PENAC is a wholly owned subsidiary of PHUSA, which, in
turn, is a wholly owned subsidiary of KPENV.

         Pursuant to the Letter Agreement, dated November 5, 2002 (the "WRH
Letter Agreement"), among W.R. Hambrecht/QIC, LLC, a California limited
liability company ("WRH"), W.R. Hambrecht/QIC Management, LLC, a California
limited liability company ("WRH Management"), and PENAC, attached hereto as
Exhibit 1 and incorporated herein by reference, WRH, WRH Management and PENAC
terminated the Shareholders Agreement, dated as of August 1, 2001 (the
"Shareholders Agreement"), among WRH, WRH Management and PENAC. Prior to the
termination of the Shareholders Agreement, the Reporting Persons believed that
they, WRH and certain individuals and entities related to WRH (the "WRH Group")
could have been deemed to constitute a "group" for purposes of Section 13(d)(3)
of the Securities Exchange Act of 1934 and Rule 13d-5(b)(1) promulgated
thereunder. As a result of termination of the Shareholders Agreement, the
Reporting Persons believe that they and the WRH Group can no longer be deemed to
constitute a "group" for such purposes.

         Zymed, Inc., a California corporation ("Zymed"), a wholly owned
subsidiary of PENAC which PENAC acquired in connection with the acquisition by
KPENV of the Healthcare Solutions Group of Agilent Technologies, Inc., a
Delaware



CUSIP Number: 748773 10 8                                           Page 6 of 22


corporation ("Agilent"), which was consummated on August 1, 2001, is a
non-control member of WRH. Based on Quinton's Registration Statement on Form S-1
filed on February 22, 2002 (as amended from time to time, the "Registration
Statement"), and the Form 3/A filed by WRH on May 7, 2002, the Reporting Persons
believe that WRH is or was the beneficial owner of approximately 5,056,215
Shares. Zymed disclaims beneficial ownership of any and all Shares held by or
otherwise beneficially owned by WRH, and this statement shall not be construed
as an admission that Zymed is, for the purposes of Section 13(d) or 13(g) of the
Securities Exchange Act of 1934 or for any other purpose, the beneficial owner
of the Shares held by WRH.

                  Certain information concerning each director and executive
officer of (i) PENAC is set forth in Schedule I hereto and incorporated herein
by reference and (ii) KPENV is set forth in Schedule II hereto and incorporated
herein by reference.

                  (b) The principal business address of KPENV is Breitner
Centre, Amstelplein 2, 1096 BC Amsterdam, The Netherlands. The principal
business address of PHUSA and PENAC is 1251 Avenue of the Americas, New York,
New York 10020.

                  (c) The primary business of each of the Reporting Persons is
the manufacture and distribution of electronic and electrical products, systems
and equipment, as well as information technology services.

                  (d) None of the Reporting Persons or, to the best knowledge
and belief of the Reporting Persons, any of the individuals listed on Schedule I
or II has, during the past five years, been convicted in any criminal proceeding
(excluding traffic violations or similar misdemeanors).

                  (e) None of the Reporting Persons or, to the best knowledge
and belief of the Reporting Persons, any of the individuals listed on Schedule I
or II has, during the past five years, been a party to a civil proceeding of a
judicial or administrative body of competent jurisdiction and as a result of
such proceeding was or is subject to a judgment, decree or final order enjoining
future violations of, or prohibiting or mandating activities subject to, federal
or state securities laws or finding any violation with respect to such laws.

         (f) KPENV is a company incorporated under the laws of the Netherlands.
PHUSA and PENAC are Delaware corporations.

         This Item 2 is qualified in its entirety by reference to Schedules I
and II which are incorporated herein by reference.

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

         Pursuant to the Asset Purchase Agreement, dated as of November 17,
2000, between Agilent and KPENV, and the Amendment and Supplemental Agreement,
dated as of August 1, 2001, between Agilent and KPENV, on August 1, 2001, PENAC
acquired 19 shares of Class A Common Stock and 2,330,000 shares of Series A
Preferred Stock of Quinton for $4,000,000, the source of which funds was working
capital. Each share of Series A Preferred Stock was convertible into one share
of Class A Common Stock at the option of the holder, subject to certain
adjustments.

         Pursuant to Article III(d)(3)(ff) of the Certificate of Amendment of
Articles of Incorporation of Quinton, dated June 2, 1998 (the "Certificate of
Amendment"), the holders of Series A Preferred Stock were entitled to receive
certificates of adjustment regarding certain anti-dilution adjustments upon the
grant of certain shares of Class A Common Stock or certain options to purchase
shares of Class A Common Stock under Quinton's 1998 Equity Incentive Plan. In
place of these certificates of adjustment PENAC was granted 287,977 additional,
uncertificated shares of Series A Preferred Stock, recorded on the books of
Quinton as of August 1, 2001.

         On April 5, 2002, pursuant to a 2.2-for-1 stock split and a
redesignation of the Class A Common Stock into Shares, the 19 shares of Class A
Common Stock held by PENAC were redesignated into 8 Shares.

         As a result of a 2.2-for-1 stock split and conversion of the Series A
Preferred Stock into Shares at the closing of the initial public offering
referred to in the Registration Statement, the 2,617,977 shares of Series A
Preferred Stock held by PENAC were converted into 1,189,989 Shares.

         The Reporting Persons have not purchased or sold any securities of
Quinton in the last 60 days.



CUSIP Number: 748773 10 8                                           Page 8 of 22


         None of the persons listed on Schedule I or II hereto has contributed
any funds or other consideration towards the purchase of the shares of Quinton
reported in this statement.

         Information about the WRH Group is disclosed in the Registration
Statement and the WRH Group Reports.

ITEM 4.  PURPOSE OF TRANSACTION

         Pursuant to a Letter Agreement, dated February 19, 2002 (the "Agilent
Letter Agreement"), by and among PENAC, KPENV and Agilent, attached hereto as
Exhibit 2 and incorporated herein by reference, PENAC is a successor in interest
to Hewlett-Packard Company, a Delaware corporation ("HP"), in an Investors'
Rights Agreement, dated as of May 27, 1998 (the "Investors' Rights Agreement"),
between Quinton, WRH and HP, attached hereto as Exhibit 3 and incorporated
herein by reference.

         Pursuant to the Investors' Rights Agreement, subject to certain
conditions and limitations set forth therein, WRH and PENAC may require Quinton
to use its best efforts to include their Shares in any registration by Quinton
of its Shares at Quinton's expense. These registration rights are subject to
conditions and limitations including that, if the registration is in connection
with an underwritten public offering, the holder is obligated to participate in
the underwriting and the underwriters have the right to exclude all or limit the
number of the holder's shares included in the registration statement. The
Investors' Rights Agreement also imposes certain restrictions on the transfer of
shares held by WRH and PENAC, and by any successors in interest to them,
including requiring any transferee to agree to be bound by the transfer
restrictions in the Investors' Rights Agreement and requiring either that an
effective registration statement cover the disposition or that Quinton be
notified of the disposition by the transferor and that the transfer not require
registration.

         In March, 1999, Quinton, Inc. ("QIC"), a Washington corporation and a
wholly owned subsidiary of Quinton, formerly known as Quinton Instrument
Company, signed an Original Equipment Manufacturer and Distributor Agreement
(the "OEM Agreement") with Zymed, effective as of July, 1998, providing for the
purchase of certain Holter monitoring items, and appointed QIC the exclusive
distributor of such products in the United States and Canada for a period of
five years. If the parties mutually agreed, the OEM



CUSIP Number: 748773 10 8                                           Page 9 of 22


Agreement could be extended for an additional five years. The OEM Agreement is
attached hereto as Exhibit 4 and incorporated herein by reference. According to
the Registration Statement, the products supplied under this agreement
represented a significant portion of Quinton's revenues, approximately 8% in
1999, 12% in 2000 and 3% in 2001. In the third quarter of 2000, Zymed terminated
the OEM Agreement because the parties failed to agree on pricing and volume
requirements as was required to be done annually under the OEM Agreement. The
OEM Agreement provided for a 180 day notice period that expired in February
2001. QIC disputed this notice of termination and in November 2000 initiated a
lawsuit in the United States District Court for the Western District of
Washington against Zymed, Agilent and HP, seeking damages against the defendants
for harm to its business resulting both from Zymed's termination of the OEM
Agreement and a variety of other alleged wrongful and tortuous conduct. QIC is
seeking monetary damages. On April 8, 2002, the court entered an order
dismissing all of QIC's claims other than the claims related to breach of
contract. The trial date, originally scheduled for late April 2002, was first
reset for September 18, 2002, and has now been reset for January 6, 2003.

         The Reporting Persons believe that the claims QIC has made in
connection with the lawsuit are without merit and can likely be successfully
defended, and they are cooperating in a vigorous defense of such claims.
Regardless of the underlying merit of such claims, however, and notwithstanding
the lack of success of prior efforts, the Reporting Persons and/or their
respective subsidiaries may from time to time engage in mediation and/or
negotiations with Quinton and QIC with a view to resolving such claims. Any such
mediation and/or negotiations may or may not include discussions concerning --
and any resolution of such claims may or may not include -- the acquisition or
disposition by the Reporting Persons of Shares or other securities of Quinton,

Rights Agreement, and subject to conditions and limitations, WRH and PENAC may

registration by Quinton of its Shares at Quinton's expense. These registration
rights are subject to conditions and limitations including, if the registration
is in connection with an underwritten public offering, the holder's obligation
to participate in the underwriting and the right of the underwriters to exclude
all or limit the number of shares included in the registration statement. The
Investors' Rights Agreement also imposes restrictions on the transfer of shares
held by WRH and PENAC, and by any successors in interest to them, including
requiring any transferee to agree to be bound by Section 2 of the Investors'
Rights Agreement (which section contains the restrictions on transfer) and
requiring either that an effective registration statement cover the disposition
or that Quinton be notified of the disposition by the transferor and that the
transfer not require registration.
