The system – depending on the accessories – can be applied for the examination of adults or children and is available in installed and portable version. All systems are supported by the same background software, thus it is not necessary for the users to learn new skills when changing to another version.

The measuring and analyzing software uses Windows, the most popular OS, which makes the application and the learning of this system easier. This significantly simplifies the recording process of the patients’ personal data, the storage and export of the measurements’ results and their display at any time.

 

 


System

Patient ManagerPatient Manager

The icon gives a shortcut to reach the patient manager. Here, patient data can be registered together with the identification (ID) code. The ID-code is generated automatically by the software for each patient.

Further documentation (e.g. creating patient groups, export/import of data, recording of all information about the patient and the examination), and reload of the previously saved primary curves can be carried out also here.

Control functions are available from the shortcut icons located above the monitoring field and in the drop-down menus.

ECG monitoringECG monitoring

For example:

  • Time- or heartcycle-based recording,
  • Setting the speed of display (6 levels, 2.5 mm/sec – 200 mm/sec),
  • Setting the amplification,
  • Splitting the monitoring field,
  • Notes,
  • Analysis function.

Offline ECG analysisOffline ECG analysis

Evaluation of data (Analysis)

The software provides two ways for the evaluation:

  • online, during the examination,
  • offline, from the primary curves of the closed or any of the previously archived examinations.

Both options are available from Analysis menu.

Online ECG reportOnline ECG report

Online evaluation

After recording, the system calculates the parameters (shown in the figure) averaged from at least five cycles of any of the recorded leads. The calculated parameters are recorded in a table and can be printed out together with the primary curves and personal data of the patient by clicking the Print icon.

Offline evaluation

The primary curves saved immediately after the examination, or any of the previously archived ones, can be reloaded and re-evaluated. For the evaluation, the program gives six ways which are accessible via the Analysis drop-down menu.

How can it help?

CARDIOSYSBASIC is a comprehensive heart electrophysiological (ECG) measuring and analyzing system which can be rapidly and effectively used in the clinical practice, and in general or sports medicine. The main advantage of the system is that, due to the possibilities given by the software, the acute and chronic pathological changes caused by arrhythmia can be profoundly evaluated using the traditional electrode arrangement (ten leads). As an example, the etiology of "sudden cardiac death" - one of the main and serious problems of our age – the development of which can be investigated with the available systems complicatedly and only partially.

"Sudden cardiac death” is a common cause of death in the developed countries. In most of the cases, no observable structural heart disease can be verified in its background, and it can occur in apparently healthy people as well[1]. In younger individuals, "sudden cardiac death” is often caused by hereditary diseases resulting in arrhythmias, such as the congenital long QT syndrome (LQTS) leading to disorders in the repolarization of heart muscle[2]. Phenotype is highly variable in patients with LQTS, and the individual susceptibility to arrhythmias can be completely different also in patients having the same LQT mutation[3]. In patients carrying subclinical LQT mutation and having normal length of QT interval measured by conventional ECG technique, life-threatening arrhythmias or "sudden cardiac death” can occur due to drugs or dietary factors which prolong cardiac repolarization[4]. Currently it is a major problem in the clinical practice to estimate the risk of and predict the incidence of life-threatening arrhythmias [5].

Furthermore, it would be of primary importance to assess the arrhythmogenic (proarrhytmic) risk as a side effect of drugs currently under development. However, the existing methods, focusing mainly on the prolongation of repolarization and on the potential inhibitory effects on the IKr current, cannot give reliable data [6-7].

The concept of repolarization reserve was formed in relation to the above mentioned problems[8-9] and its predictive value has been proven experimentally[10-11]. According to this concept, if the repolarizing function of one ionic current in the heart muscle decreases due to congenital or acquired causes, it will not necessarily result in clinically observable prolongationof repolarizationand in arrhythmia (merely in decreased repolarization reserve), since the other ionic currents are able to compensate for the missing function. However, if repolarization is further inhibited (even mildly, e.g. by non-cardiovascular drugs or by dietary factors), significant prolongation of the QT interval and severe ventricular arrhythmias can occur, which can cause “sudden cardiac death”.

In the recent years, the use of a new ECG parameter has been proposed as a more reliable predictor of proarrhythmicrisk and for the investigation of repolarization reserve. This is the beat-to-beat measurement of QT interval variability, characterizing the instability of cardiac repolarization, which can be numerically defined as short-term variability of the QT interval[12]. The increment of short-term variability was better correlated with the incidence of serious ventricular arrhythmias occurring later than the conventional ECG parameters, both under preclinical [13-14] and clinical circumstances [15-17].
