The European Community concerted action on ambulatory monitoring.

The diffusion of instruments for ambulatory monitoring is rapidly expanding and the related cost to the European Community is increasing, while their role and their effectiveness are still controversial. The Biomedical Engineering Group, belonging to the Committee for Medical Research of the European Community, has approved a project for the co-ordination of the research ('concerted action') in the field of ambulatory monitoring, to tackle the problem. The project, directed by a Project Management Group, following some meetings of experts being organized to identify high-priority goals, has been aimed at promoting common efforts in two specific fields: evaluation of the quality of ECG ambulatory monitoring analysers, by means of a standard reference, and assessment of the performance of non-invasive techniques for arterial blood pressure ambulatory monitoring. In its first six months (July-December 1985) the project has produced: (1) a preliminary agreement about ECG recording and an annotation scheme, to be definitely adopted, after a pilot experiment, by June 1986; (2) a protocol for hypertensive patient characterization and data collection, to be initiated by September 1986.

Electrocardiographic and signal monitoring in ischaemic heart disease: state of the art and perspective.

The current role of ECG and signal monitoring in the diagnosis of Ischaemic Heart Disease is outlined in relation to imaging techniques giving accurate information on myocardial anatomy and function. ECG monitoring during stress testing remains the first step non-invasive method providing pathophysiological information. Long term continuous monitoring of the ECG and of other signals (e.g. arterial blood pressure and respiration) is commonly used to control patients with suspected or ascertained IHD. Progress of technology and of signal processing methods are driving the exploitation of signal information for diagnosis, prognosis and therapy control of ischaemic patients.

Electrocardiography↗

Imaging-documented cardiovascular signal database for assessing methods for ischaemia analysis.

A new database of cardiovascular signals has recently been developed at the CNR Institute of Clinical Physiology in a study based on patients admitted to the Coronary Care Unit for suspected ischaemic heart disease (IHD), who underwent both ECG effort stress test and echo or radionuclide diagnostic imaging procedures associated with pharmacological test of myocardial ischaemia. During stress testing, in addition to 12-lead ECG, arterial blood pressure and respiration signals are measured non-invasively and recorded. Signals and representative image frames at baseline and during ischaemia are stored in the database, which is planned to include 50 cases, annotated beat by beat and archived on CD-ROM. Each case also contains resting ECG and a comprehensive patient clinical record; if possible Holter ECG and coronary arteriography frames.
