The Centre of Excellence STIMCARD operating within the Institute of Medical Equipment and Technology ITAM develops Polish technologies of transesophageal, transcutaneous and transvenous cardiac stimulation as well as technologies supporting the supervision of patients undergoing electrocardiotherapy, such as in the case of an implanted pacemaker or cardioverter defibrillator. The paper reviews non-invasive electro stimulation techniques, as well as the diagnosis and therapy of the coronary artery disease (CAD) and arrhythmias. As far as CAD is concerned, the paper presents solutions applied in the construction of electrodes and pacemakers intended for both transesophageal and transcutaneous cardiac stimulation tests. The clinical value of the developed cardiac stimulation test has been assessed for the diagnosis of stable cardiac symptoms and management of patients with unstable cardiac disease, as well as for the identification of subjects in danger of sudden cardiac death. The system of stimulated ischemic preconditioning has also been discussed. Also, the paper demonstrates dedicated solutions used in ECG recording channels in the area of diagnosis and treatment of arrhythmias. The solutions make it possible to obtain stable and interpretable recordings during stimulation, both on the surface of the body and in the esophagus. Finally, the paper analyses solutions introduced in pacemakers which make it possible to induce (for diagnostic purposes) and stabilize quick paroxysmal heart arrhythmias, as well as the idea of supported hemodynamics, particularly useful during surgery.

The work has been aimed at evaluation of ECG records quality during transcutaneous heart stimulation performed in the three-electrode layout by means of a new analog Artefact-Elimination System (AES) external to the recoder. The transcutaneous ventricular stimulation was performed with the use of noninvasive cardiostimulator NAP-601 (ITAM Zabrze) coupled with transesophageal cardiostimulator SP-5 plus eqipped additionally with the analog AES in ECG recording channel. Efficacy of the system has been evaluated in 15 patients at a duration of artefact elimination equal to 60 and 120 ms. Threshold of ventricular excitation was 47 mA and was located within a range 33 to 80 mA.

The paper presents the results of study on optimizing of ECG-signal filtration in case of ECG recordings during noninvasive transesophageal and transcutaneous diagnostic and therapeutic heart stimulation. The study comprised an effectiveness of hardware-software noninvasive stimulator artifact elimination system applied in electrocardiograph DEK-631 (ITAM – Zabrze) as well as the effectiveness of analogous circuit of spike artefacts elimination applied in recording channel of diagnostic cardiostimulator SP-5plus (ITAM). The influence of filtration on a quality of ECG signal recorded and a possibility of drawing the objective diagnostic conclusions have been assessed. Analogous artifact elimination system (AES) contained in SP-5plus ensured obtaining of good quality of ECG recording during noninvasive stimulation of atria and ventricles in all diagnostic and therapeutic applications.

The paper describes implementation of a new technology of digital systems design in case of medical measurement interface of IMPULS system used for acquisition of ECG signal from pacemaker patients. Similarly as in other applications, the processor circuit is a base of digital system, however - regarding large number of performed tasks - it is assisted by additional peripheral logic circuits. At the beginning, there were used standard elements (logic gates, counters, registers, etc.), however a growing complexity of beyond processor operations encouraged designers to apply the programmable circuits. The paper presents the stages of digital system development that has been implemented in medical measurement interface. It is the excellent example of possibility to integrate several standard elements in one integrated circuit.

W pracy przedstawiono możliwości diagnostyki i terapii kardiologicznej wykorzystujące techniki nieinwazyjnej elektrostymulacji serca, prowadzonej z użyciem wielofunkcyjnego urządzenia DiagnoStim MDD-501. Na przykładach pacjentów, u których urządzenie spełniło jednocześnie funkcję diagnostyczną i terapeutyczną oraz pacjentów, u których diagnostyczne możliwości urządzenia zadecydowały o wdrożeniu lub zaniechaniu dalszego postępowania inwazyjnego, przedstawiono przegląd technik dostępnych z zastosowaniem MDD-501, wskazując na jego niezwykłą przydatność w sprawnym rozwiązywaniu problemów kardiologicznych.

The aim of this work was the development of computerized follow-up system for implanted pacemakers integrated with data base of simulated patients. Measurement interface of the system converts a patient's ECG signal and independently the stimulator impulses received from limb leads. Data blocks containing samples of ECG signal, stimulator impulses and calculated measurement results are transmitted via isolating optocouplers and bidirectional circuit RS-485 to fast card RS-485 in the computer of measurement station. Computer software of this station, operating in WINDOWS '95 (98) environment, enables: receiving the measurement data from interface, data collection in mass memory, presentation of data and traces a monitor screen as well as databases handling of the patient operations, implants and measurement. All the pacemaker measurement are performed simultaneously 'Learining procedure enables the automatic recognition of pacemaker operation mode and matching the measurement channel to values of pacemaker parameters.
