INTRODUCTION

Manual Organization This manual explains in detail how to install and use the PC-ECG 1200. At the beginning of each application chapter, there is a Quick Start section, which is a brief explanation of how to carry out a study, including the keyboard short-cuts for the main functions. If you are familiar with ECG procedures, you can use this Quick Start section to get up and running quickly. The software must be installed before the hardware. See Software Installation, page 7 and Hardware Installation, page 13.

Programs Each program has a specific purpose. The following is a brief description of when to use each one: Rest

Records and measures short ECG tests on patients in resting position (up to 10 seconds) Records and measures ECG tests on patients under stress conditions using a predefined test protocol. The stress test includes 3 basic stages: • Rest

Stress

• Stress • Recovery Each stage may be divided into more than one phase according to the testing protocol used.

Monitor

Works with an ECG device to record, monitor and save a prolonged ECG test in rest condition

HRV

Tests according to time how patient pulse and heart rate varies with load, medication, etc.

LP

Predicts tendency to ventricular tachycardia

Database

Indications for Use of the PC-ECG 1200 ECG Intended Use ECG is intended to disclose either normal condition or patterns of arrhythmia, myocardial ischemia, rate abnormalities, or features of prognostic value in the following cases: ◊

Patients with suspected cardiac abnormalities

◊

Populations of patients at an age or period in which a routine baseline evaluation of ECG characteristics is desired.

QT Analysis is useful in the assessment of long QT syndrome (LQTS). In some instances, LQTS can be corrected by pharmacological therapy. QT analysis is also used to measure QT dispersion, the difference between maximal and minimal QT values. QT dispersion is a measure of the inhomogeneity of ventricular repolarization. The PC ECG 1200 has been tested to measure Heart Rate Variability to within 1 millisecond tolerance. The clinical significance of Heart Rate Variability measures should be determined by a physician. The PC ECG 1200 has been tested to measure Late Potential to a tolerance of within 1 millisecond, and 1 microvolt. The clinical significance of Late Potential measures should be determined by a physician.

Stress Testing Intended Use Angina pectoris (chest pain) is a clinical syndrome resulting from myocardial ischemia, indicative of reduced blood supply to the cardiac muscle. The electrocardiogram may establish the diagnosis of ischemic heart disease if characteristic changes are present. Stress testing is the most widely used method to decide whether this chest pain is related to myocardial ischemia, and thus to coronary artery disease. In stress testing, the contractile capability of the heart muscle is monitored via ECG during patient exercise. Patients exercise by bicycle, treadmill, or other means, while the ECG is monitored continuously. Exercise loads are determined by predefined protocols. The ECG signals are recorded for the resting, exercise, and recovery phase portions of the exercise protocol. The changes in ECG waveforms are compared to the resting ECG records. Most of the commercial stress test systems control the bicycle or treadmill automatically according to the requirements of the chosen protocol, although this is not essential. ST segment monitoring is intended as an aid in the evaluation of myocardial ischemia in patients with known or suspected coronary artery disease. The ST segment algorithm has been tested for accuracy of the ST segment data, and a database is used as a tool for performance testing. The significance of the ST segment changes must be determined by a physician.

Table 2: Printers Installation Requirements Installing the Thermal Printer Use a 4 inch or 8 inch thermal printer. The thermal printer driver is installed separately from the PC-ECG 1200 program. A thermal printer can be supplied by Norav (MP200, 8 inch). This printer requires the purchase of a dongle with P1 license permission. The MP200 driver is available on the PC-ECG 1200 CD at the following path: "<CD>:MP200OEMPRINT.inf".

Installing or Updating The PC Software Install the software before installing the hardware. If the device is connected to the PC, disconnect the device before installing the software. Note:

The software package works under Windows NT, 98, ME, 2000, and XP operating systems.
