Abstract

In this article, a new ECG data compression technique is proposed. The method relies on modelling quasi-periodic ECG signals as a dynamic Fourier series. Fourier coefficients are continuously estimated using the adaptive least-mean-square algorithm. Results from simulated normal and pathological ECGs are presented and discussed. A comparison with other compression techniques is also discussed.

[Continuous ECG monitoring. A valuable technique in acute myocardial infarction].

Early diagnosis of acute myocardial infarction is important to enable myocardial injury to be limited by means of various treatments. Monitoring of vessel patency with vector cardiography or continuous 12-lead ECG recording is a form of surveillance that has been widely accepted in Sweden. In post-reperfusion therapy monitoring, there is approximately 80 per cent agreement between monitoring ST-segment changes and acute coronary cardiography. For risk stratification of patients with unstable angina or non-Q-wave infarction, ST-segment monitoring manifests great predictive power which is further enhanced by its combination with the measurement of highly specific markers of myocardial injury. Computerised techniques for continuous monitoring of multiple ECG leads have contributed much to our understanding of the dynamics of acute coronary heart disease. Valuable prognostic information is available in real time, early identification of myocardial injury is possible, and treatment strategies can be based upon more reliable grounds.

Long-term memory monitoring in infant tachycardias.

Evaluation and detection of pathological tachycardias in infants sometimes is difficult. Noninvasive recording of the infant's ECG at the time of symptoms forms the mainstay of diagnosis, although invasive electrophysiological testing may be required. Accurate rhythm diagnosis is central to successful treatment. The advent of high capacity ambulatory memory monitoring makes it possible to record ECG signals, as well as apnea data. We present two cases of infant tachycardia studied by memory monitor. These devices yield good quality ECG signals and may provide information regarding a particular rhythm disturbance.
