Electrocardiomultigraphimeter using a home computer.
The drop in hardware costs has fostered the widespread use of home-computer systems. Because of this situation, the home computer can be profitably employed in some highly specialized fields. We believe electrocardiographic instrumentation to be one such field. We have built an electrocardiomultigraphimeter (ECXGM), which can be considered as a development of the traditional electrocardiograph that performs some additional functions. Our prototype features vectorcardiography, polar coordinate tracing, automatic measurements between fiducial points selected by the user with a joystick and screen cursor and trace filing by patient on labelled floppy disks. The standard hardware consists of a Commodore 64 console, a monitor, two floppy disk drives and an Epson HI-80 plotter, all of which are readily available. The special hardware consists of an A/D converter, which receives the electrocardiographic signal downstream of the amplifying stage, which is a standard feature of any electrocardiograph. Prototype development mostly involved the software. Difficulties were posed by the limited resources available on home computers, an important point in view of the problem to be tackled. The solutions adopted are based on the use of assembler language and overloading techniques and minimizing the interconnections among the software modules defined in a compactly built program. The result is an instrument with significantly advanced clinico-scientific capabilities as compared to current electrocardiographic instruments. This fact, and the class of the hardware used and special software built, confer originality to this work. The new instrument ought to be especially suitable for the offices of cardiologists who have an interest in such capabilities, and for schools of electrocardiography.

A manifesto on telehealth and telemedicine.
An evident contrast exists between the generally easy way medical doctors and administrators use the term "telemedicine" and the wide variety of significantly different technologic methods and devices necessary for correctly performing specific tasks in the field. Many misunderstandings could be avoided by agreeing on the types of services that telemedicine can provide, names for those services, and descriptions of what is included in the services. This manifesto lists representative services, with a proposed name for and description of each.

A microprocessor-based device for synthesis of R-R interval values during ambulatory monitoring.
A microprocessor-based system devoted to ambulatory monitoring of heart-rate variability (HRV) is described. Mainly it measures R-R intervals after QRS detection and provides a real-time quantification of the HRV. The concept of derived successions and a suitable set of graphical summaries are used. The hardware is based on CMOS technology; the mobile part of the system is battery operated. The results are printed-out by the fixed part of the system, they can also be fed into a general-purpose computer. Other applications of the system are suggested.

Object-orientated DBMS techniques for time-oriented medical record.
In implementing time-orientated medical record (TOMR) management systems, use of a relational model played a big role. Many applications have been developed to extend query and data manipulation languages to temporal aspects of information. Our experience in developing TOMR revealed some deficiencies inside the relational model, such as: (a) abstract data type definition; (b) unified view of data, at a programming level; (c) management of temporal data; (d) management of signals and images. We identified some first topics to face by an object-orientated approach to database design. This paper describes the first steps in designing and implementing a TOMR by an object-orientated DBMS.
