## Indications for use
ECG intended use: ECG is intended to disclose either normal condition or patterns of arrhythmia, myocardial ischeria, rate abnormalities, or features of prognostic value in patients: 1)suspected of cardiac abnormalities, or 2) in populations of patients at an age or period in which a routine baseline evaluation of ECG characteristics are desired. 3) QT Analysis is useful in the assessment of long QT syndrome (LQTS). In some instances, LQTS can be corrected by phanrmacologic 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. 4) The PC ECG 1200W System has been tested to measure Heart Rate Variability within 1 millisecond tolerance. The clinical significance of Heart Rate Variability measures should be determined by a physician. 5) The PC ECG 1200W System has been tested to measure Late Potential within 1 millisecond tolerance in the time domain, and 1 microvolt tolerance in voltage. The clinical significance of Heart Rate Variability 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 a 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 thereby coronary artery disease. In stress testing, the contractile capability of the heart muscle is monitored via ECG during patient exercise. Patients are exercised by bicycle, treadmill, or other means while continuously monitoring the ECG. Exercise loads are determined by predefined protocols. The ECG signals are recorded for the resting, exercise and recovery portions of the exercise protocol. The changes in ECG waveforms are compared to the resting ECG records. Although not necessary, most of the commercial stress test systems control the bicycle or treadmill automatically according to the requirements of the chosen protocol. 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 has been used as a tool for performance testing. The significance of the ST segment changes must be determined by a physician.
