Intended Use

The Philips Holter Analysis System provides measurements, data, and reporting of parameters such as normal sinus rhythm, arrhythmias, QT and ST measurements, paced beats analysis and HRV, that can be used by a qualified clinician for the evaluation of:

• Symptoms that may be related to rhythm disturbances of the heart in adult patients.
• Risk in patients with or without symptoms of arrhythmia. QT measurement information is provided to support this assessment by a competent health professional.
• Efficacy of antiarrhythmic therapy
• Pacemaker function
• Symptoms that may be associated with myocardial ischemia

The Philips Holter Analysis System is not intended for use for pediatric patients.

The EASI derived 12-lead ST measurements are not recommended unless patients meet the following parameters:

• Age: Between 33 to 82 years
• Height: Between 147 to 185 cm (58 to 73 inches)
• Weight: Between 53 to 118 kg (117 to 261 lbs)
• Height to Weight Ratio: Between 1.41 to 2.99 cm/kg (0.25 to 0.54 in/lb)

If patients do not meet these parameters, the EASI derived 12-lead ST measurements are not intended for use. EASI derived 12-Lead ECGs and their measurements are approximations to conventional 12-Lead ECGs and should not be used for diagnostic interpretations.

Device Description

The Philips Holter Analysis System (hereinafter known as Philips HAS) is offered as standalone software. It is intended to be installed into a user's PC (general purpose computing platform). The product evaluates the heart rhythms of ambulatory ECG data over an extended period and generates a preliminary analysis for physician's review. The ECG data is downloaded from compatible ambulatory ECG recorders. It is to be used by trained personnel.

The Philips Holter Analysis System accepts ECG recordings from DigiTrak XT recorders (K071733) and analyzes the patient's heart activity for the recorded period, typically from 24 hours up to 7 days. The analysis is not performed in real time. The DigiTrak XT recorder collects up to 168 hours (7 days) of ambulatory ECG. The software can analyze up to 168 hours (7 days) of contiguous ECG data.

The algorithm (Zymed Algorithm, also internally referred to as the CAlg-Holter Algorithm) used in Holter Analysis System was first developed and approved for use in the Holter Scanner Model 1210. It was continually updated and subsequently cleared for use in more Holter Models. It includes Heart Rate Variability (Time Domain) as a standard software report configuration in March 1996. The operating system converted from a DOS operating system to a Windows operating system in April 1999. Heart Rate Variability Frequency Domain was added in February 2001. The QT analysis was added in September 2001. The most recent 510(k) including above features and functions is under K010949.

The Zymed Algorithm in the HAS incorporates the following enhancements in the subject device:

• Upgraded AFIB detection by replacing the current algorithm with the Philips ST/AR AFIB algorithm's P wave detection feature. The feature was cleared in K101521 with Philips ST/AR ST and Arrhythmia Software.
• Enhanced HRV reporting by replacing current calculations with advanced data warehouse calculations from PhysioNet. Incorporated Nonlinear HRV to provide more characterization of heart rate variability that linear methods could miss.
• Incorporated bug fix, and code security
• Upgraded compiler

The EASI derived 12-lead display function was cleared in K020456. It remains unchanged in the subject device. Philips does not incorporate any additional usage in the subject device beyond these clearances. The EASI 12-lead is only for display purposes, allowing end users to visualize EASI lead ECG recordings in a traditional 12-lead format. EASI derived 12-Lead ECGs and their measurements are approximations to conventional 12-Lead ECGs and should not be used for diagnostic interpretations.

No automatic functions or analyses utilize this data. The Zymed Algorithm performs its analysis on the raw ECG signal and does not use the EASI derived 12-lead in that analysis.

The Philips Holter Analysis System requires operator's intervention during and after the initial analysis. The Philips HAS allows the operator to view and print out an analysis report, individual heart rate strips, as well as a full disclosure report for physician's review, diagnoses, and observations. It is intended to assist the qualified medical professional in the interpretation of the recorded data; it is not intended to serve as a substitute for the review and overread of the recorded ECG data.

The Philips Holter Analysis System provides viewing, printing, and report capabilities as listed below:

• A view of the data and a summary of the heart events that have taken place
• Detection of anomalies such as ventricular ectopy and supraventricular ectopy
• Patency of the pacemaker and pacemaker anomalies
• Advanced scanning techniques, such as determining ST and QT anomalies
• Heart rate data and heart rate variability
• Full disclosure reports

The Philips Holter Analysis System can operate in a networked environment that includes the following devices and interfaces to transfer orders and Holter reports.

• Philips IntelliVue Information Center (PIIC) (K153702)
• A fleet of Holter Remote Links and one or more Holter Central Links
• IntelliSpace ECG Management System (ISECG) (K120855)
• An IntelliBridge Enterprise (IBE) data interface engine / brokering system
• DICOM-based enterprise systems

PIC , Holter Remote Links, and Holter Central Links provide alternate ECG input mechanisms for Holter analysis. ISECG Central Link, Report Viewer, and IBE can accept Holter reports. IBE can provide Orders and ADT information for HAS. DICOM-based systems support patient orders via DICOM Modality Worklist and accept exported DICOM Encapsulated PDF reports.

The Philips Holter Analysis System provides three models with different configurations for customers to select: Series 3000, Series 5000, and Series 7000.
