                                       4





         This Amendment No. 4 amends and restates in its entirety the Schedule
13D/A filed by the Reporting Persons (as defined herein) on March 28, 2003.

ITEM 1.  SECURITY AND ISSUER

         The class of equity securities to which this statement relates is the
shares of common stock, with par value of $0.001 per share (the "Shares"), of
Quinton Cardiology Systems, Inc., a Delaware corporation ("Quinton"). According
to a report on Form 8-K filed by Quinton with the Securities and Exchange
Commission on May 21, 2003, Quinton is the successor, by means of a
reincorporation merger, to all of the business, properties, assets and
liabilities of Quinton Cardiology Systems, Inc. (formerly QIC Holding Corp.), a
California corporation ("Quinton California"), which was merged with and into
Quinton. Pursuant to that merger, each outstanding share of common stock, no par
value per share, of Quinton California (the "California Shares") was converted
into one Share. In this statement, the terms "Quinton" and "Shares" may refer,
as context requires, respectively to Quinton California and to the California
Shares.

         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.

         Certain information concerning each director and executive officer of
(i) KPENV is set forth in Schedule I hereto and incorporated herein by
reference, (ii) PHUSA is set forth in Schedule II hereto, and (iii) PENAC is set
forth in Schedule III hereto and is, in each case, 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, II or III
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, II or III
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,
II and III, which are incorporated herein by reference.

ITEM 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

         Pursuant to the Asset Purchase Agreement (the "APA"), dated as of
November 17, 2000, between Agilent Technologies, Inc., a Delaware corporation
("Agilent"), and KPENV and the Amendment and Supplemental


                                       5


Agreement (together with the APA, the "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.

         In addition, pursuant to the Agreement, PENAC acquired 100% equity
ownership of Zymed, Inc., a California corporation ("Zymed"). The source of the
funds PENAC used to acquire Zymed was working capital.

         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 Quinton's initial public offering
referred to in the Registration Statement on Form S-1, filed on February 22,
2002 (as amended from time to time, the "Registration Statement"), the 2,617,977
shares of Series A Preferred Stock held by PENAC were converted into 1,189,989
Shares.

         As previously reported, Zymed was a non-control member of W.R.
Hambrecht/QIC, LLC, a California limited liability company ("WRH"), which the
Reporting Persons believe was the beneficial owner of approximately 5,056,215
Shares, as to which Shares the Reporting Persons disclaimed beneficial
ownership. In April 2003, the Reporting Persons concluded, on the basis of their
review of certain tax documentation received from WRH on or about March 28,
2003, that WRH had distributed the Shares it owned to its members and that
Zymed, as a non-control member of WRH, had received 225,327 Shares on or about
November 11, 2002 as part of such distribution. Zymed had been merged into PENAC
as of August 31, 2002, so such Shares were acquired by PENAC.

         See Item 5 for a discussion of transactions by the Reporting Persons in
securities of Quinton in the last 60 days.

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

ITEM 4.  PURPOSE OF THE TRANSACTION

         Pursuant to a Letter Agreement, dated February 19, 2002 (the "Agilent
Letter Agreement"), by and among PENAC, KPENV and Agilent, which is attached as
Exhibit 1 and is 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"), among Quinton, WRH and HP, which is attached as Exhibit 2 and is
incorporated herein by reference.

         The Investors' Rights Agreement imposes certain restrictions on the
transfer of shares held by PENAC, and by any successors in interest to it,
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.

         PENAC intends to sell to certain underwriters all of the Shares
beneficially owned by the Reporting Persons in connection with the public
offering of securities (the "Offering") described in Amendment No. 2 to
Quinton's Registration Statement on Form S-3 (No. 333-114908), which was filed
on May 20, 2004. In connection with the Offering, PENAC entered into a Power of
Attorney in the form attached as Exhibit 4, which is hereby incorporated herein
by reference (the "Power of Attorney"), and anticipates that its
attorneys-in-fact will execute and deliver on its behalf an Underwriting
Agreement in the form attached as Exhibit 3, which is hereby incorporated herein
by reference (the "Underwriting Agreement").

         Other than as set forth herein, none of the Reporting Persons, or to
the best knowledge and belief of the Reporting Persons, any of the individuals
listed on Schedule I, II or III hereto has plans or proposals which relate to or
would result in any of the events described by Items 4(a) through 4(j) of
Schedule 13D.

                                       6


         The foregoing discussion is qualified in its entirety by reference to
the Agilent Letter Agreement, the Investors' Rights Agreement, the Power of
Attorney and the Underwriting Agreement.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER

         (a) The percentage interest held by each Reporting Person presented
below is based on the number of Shares reported in Quinton's registration
statement on Form S-3 (No. 333-114908), filed on April 27, 2004, and as amended
on May 20, 2004.

         PENAC is the direct beneficial owner of 1,394,024 Shares, representing
approximately 11.4% of the Outstanding Shares.

         PHUSA may be deemed to beneficially own 1,394,024 Shares, representing
approximately 11.4% of the Outstanding Shares.

         KPENV may be deemed to beneficially own 1,394,024 Shares, representing
approximately 11.4% of the Outstanding Shares.

         None of the Reporting Persons or, to the best knowledge and belief of
the Reporting Persons, any of the persons listed on Schedules I, II or III
hereto beneficially owns any Shares other than as set forth herein.

         (b) Each Reporting Person has the power to vote or direct the vote and
dispose or direct the disposition of the Shares beneficially owned by such
Reporting Persons as indicated in pages 2 through 4.

         (c) There have been no transactions in the Common Stock effected by the
Reporting Persons in the last 60 days.

         (d) No other person has the right to receive or the power to direct the
receipt of dividends from or proceeds from the sale of Shares.

         (e) Not applicable.


                                       7


ITEM 6.  CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT
         TO SECURITIES OF THE ISSUER

         There are no contracts, arrangements, understandings or relationships
between the Reporting Persons (or their wholly owned subsidiaries), and to the
best knowledge and belief of the Reporting Persons, none of the persons listed
on Schedules I, II or III hereto, and other persons with respect to the Shares
aside from the Investors' Rights Agreement, the Power of Attorney and the
Underwriting Agreement. The Investors' Rights Agreement imposes restrictions on
the transfer of shares held by WRH and PENAC, and by any successors in interest
