[Automatic clinical electrocardiography laboratory of the Udine regional hospital. Considerations on 50,000 tracings automatically analyzed with computers].

Automatic ECG processing has now passed beyond the experimental stage into the realm of clinical practice. It offers the most advanced solution to the organisation problems faced by ECG laboratories, particularly in large hospitals. A centralised laboratory for this work was first set up in Italy in 1973 at the Udine Regional Hospital. Its instrumentation and organisation are described and a consecutive sample of 1000 ECGs culled from the 50,000 computerised since its inception are discussed.

[Medico-social aspects of the post-infarct state. Clinical, functional, psychological and return-to-work studies of 100 patients with myocardial infarct treated in the coronary unit].

To determine whether intensive care unit are able to improve long term as well as immediate prognosis of acute myocardial infarction, one hundred patients, aged 40 to 60 years, six months to three years after discharge have been studied. All patients were examined with ergometric test, psychological assessment and medico-social survey. Comparison was made with patients treated in general medical wards. Correlations between clinical picture, psychological pattern, functional capacity and return to work prove that treatment in a coronary care unit positively affects the future of these patients. The importance of a rehabilitation program and its principles are also discussed.

[The Caceres-USPHS (version HP-3) computer program. Evaluation of automatic analysis of 40,000 ECG (author's transl)].

The main features of Caceres-USPHS (version HP-3) program for automatic analysis of the ECG are reviewed. Our experience at the Ospedale Regionale di Udine has now reached a total of 40,000 tracings analyzed by such a program and with an HP 1530-A computer system. In a detailed study of 1,000 consecutive computer-analyzed tracings reviewed by three experienced cardiologists, 534 were normal and 466 abnormal. A high degree of specificity was detected in the normal group (only 1.5% of false negatives) while the sensivity was rather low. In the abnormal group there were 18.1% of false positives and while the agreement was 100% in complete bundle branch block and some types of infarction, it was 56% in atrial fibrillation and 47% in incomplete right bundle branch block. Program errors were more common in measurements and pattern recognition; they were unusual in the program logic (0.3%). A significant improvement over comparable data obtained one year previously was attributed to a better quality control in data recording and to increase physician acceptance of the program diagnostic criteria. On the current and past figures of accuracy, it is concluded that the version HP-3 of Caceres-USPHS program represents a step forward in computer-derived ECG interpretation. However more progress is still needed for a larger and more profitable clinical application of this ECG computer program.

[The automated ECG laboratory: equipment and operational problems (author's transl)].

In the light of recent advances in technology, the basic equipment of an automated ECG laboratory is described. The main features of data acquisition terminals, data receiver/controller units, A/D converters, computers, visual displays and systems for storage and retrieval of tracings, are briefly discussed. Three major alternatives are open for computer-aided ECG interpretation today: 1) complete, dedicated system in the hospital; 2) ECG data collection system with offline analysis by hospital business computer; 3) ECG service center outside of the hospital. Advantages and possible limitations of these methods are discussed. At the Ospedale Civile Regionale of Udine we have choosen the first method. An HP 1530 ECG interpretative system and the 12-lead ECG analysis program developed by Caceres-USPHS are used. Analog tracing and interpretative printout are available in the laboratory and/or at the patient location in about one minute. Our system has been working for less than one year. At present, 150-200 ECG are processed daily. Such an ECG processing system has proven to yield considerable savings in time and manpower. Some operational problems related to shifting from manual to computer work have been gradually overcome and will be discussed.
