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. Stress Testing 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 bioycle, treadmill, or other means, while the ECG is monitored continuously. Exercise body of treading, on one may of The ECG signals as well as the HF-QRS signals are recorded for the resting, exercise, andreasonals phase portions of the exercise protocol. The changes in both ECG waveforms are compared to the resting ECG records. In the HyperQ™ stress test, changes in the high frequency of the mid QRS complex, calculated as root-mean-square (RMS) values, are compared to the resting values. 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. HyperQ™ The HyperQ™ Software is intended to be used as an aid to the ECG stress test by means of analysis of high frequency components present within the central portion of the QRS complex. The significance of the HF-QRS changes must be determined by a physician.

The HyperQ™ AD-100 System is a compact monitor for measuring, processing, storing, and displaying information derived from an electrocardiogram (ECG). The device analyzes and records the high frequency components of the QRS complex of standard ECG.

In stress testing, the contractile capability of the heart muscle is monitored via ECG during patient exercise by bicycle, treadmill, or other means, while the ECG is monitored continuously. Exercise loads are determined by predefined protocols. The ECG signals as well as the HF-QRS signals are recorded for the resting, exercise, and recovery phase portions of the exercise protocol.

The HyperQ™ System is a compact monitor for measuring, processing, storing, and displaying information derived from the following physiological measurements: - Electrocardiogram (ECG). A twelve lead ECG is acquired and a waveform can be displayed real-time on the LCD screen, recorded or printed. The design of the ECG function is derived directly from the predicate device, the PC ECG 1200 device. - Detection, analyzing and recording of the high frequency components of the QRS complex of standard ECG signals.
