General Questions – CARDIOLOGIC EXPLORER (CAE)
Cardiogoniometry can detect cardiac ischemia (deficiency) fast and stress-free. Unlike with other methods of ischemia detection, physical or pharmacological stress are not required.
Yes, the examination is 100% non-invasive. Similar to an ECG, electrodes (however, just five) are stuck to the upper body to record the potential of the heart.
Studies have shown an average sensitivity of 75% and an average specificity of 85% depending on study design, patients and control groups and selected comparative method.For more Information
An overview of published studies is in the section “Info & Background > Study overview”
Since Cardiogoniometry is a new methodology, the study database is constantly extended.
The aim is a comparison with all known non-invasive / minimally invasive methods used for the detection of cardiac ischemia (e.g. stress test, stress echo, cardiac CT, cardiovascular MRI, scintigraphy), and also with coronary angiography.
The CARDIOLOGIC EXPLORER can be used in pre-clinical settings like GP surgeries as well as in clinical applications by a range of different specialists, such as general practitioners, internists, cardiologists, diabetologists.

The CARDIOLOGIC EXPLORER (CAE) Device
The CAE´s interface facilitates a bidirectional communication with the surgery´s IT system. This communication typically runs automatically in the background.
No, the doctor determines which modules – Cardiogoniometry, 12 Lead Rest ECG or stress ECG – will be used in the practice. The system can be upgraded to incorporate additional modules any time.
The possible combinations of the CARDIOLOGIC EXPLORER device are shown here.
No, the CAE is maintenance free.
However, regular backups of patient data are recommended.
Yes, the CAE is connected via USB to the computer on which the software was installed. All versions of Windows systems are supported, including Windows 8.
The electrodes are a very important component. Extensive tests have shown that good quality electrodes provide more accurate results. enverdis recommend the Blue AMRU Electrode which can be purchased through enverdis.
The CAE contains 3 modules.
12 Lead Rest ECG
All modules can be purchased separately. However, the stress ECG requires the 12 Lead Rest ECG module.More information
The CAE is a modular system, which offers the Cardiogoniometry module, as well as a standard 12 Lead Rest ECG and an Ergometry module.More Information
The CAE automatically generates a proposed diagnosis. The physician can refine the information manually.
The CAE can be used preventative as well as in acute diagnostic. Patients with increased cardiac risk can be analyzed rapidly and safely.
Yes, Cardiogoniometry can provide evidence particularly in cases where the non-specific ECG and biomarker tests are (still) negative.
The CAE is suited for use in prevention as well as in acute cases.
Cardiogoniometry could replace the 12 Lead Rest ECG. However, the guidelines specify that an ECG and troponin test are mandatory. The CGM can provide a more accurate and safer diagnosis. In many cases, ECG and biomarker examinations where negative, while the CGM shows clear signs of ischemia.
The CAE can be used in both fields – preventative and in acute cases.

Initially, check the proper placement of the electrodes. In addition, ensure the patient holds his breath during the 12-second test or breathes only very lightly.
Cardiogoniometry can detect an ischemia much earlier, since in an ECG an automatic algorithm determines the times of the individual sectors or amplitudes on a reference heartbeat (Referenzschlag). An interpretation by the doctor is another alternative. Both options have disadvantages which can be resolved by using Cardiogoniometry. The algorithms only measure one reference heartbeat, which is representative for all others. This means a lot of information is lost.
In Cardiogoniometry, all heartbeats of one reading are compared to each other, using especially developed algorithms and procedures. In addition, further data is evaluated and set into predefined relation.
Yes, locating the ischemia is possible in most cases. This depends upon the set of parameters.

The CAE is a modular system. In addition to the Cardiogoniometry methodology, classic 12 Lead Rest ECG and stress tests can also be performed.More information
The CAE enables doctors to perform a stress ECG/Ergometry. This is one of three modules on offer. This requires the module 12 Lead Rest ECG.More information
The operation of the software is intuitive and the administration of the test can be delegated. The system provides step-by-step illustration and checks for the correct application of the electrodes. The initial training includes both, the work with the software and application of electrodes.
Attaching the electrodes only takes a moment. The accuracy of attaching the electrodes is quite important, but it is as easy as attaching electrodes for an electrocardiogram.
The patient should be stripped to the waist, lie comfortably and as flat as possible. Before attaching the electrodes, the skin should be oil-free and in case of thick chest hair, possibly shaved.
The examination and recording of the signal takes only 12 seconds incl. evaluation and automatic reporting. The time it takes altogether is approximately 2-3 minutes, which includes the patient undressing prior to the examination, applying the electrodes and getting dressed again afterwards.
The software provides different possibilities: The Print Manager allows for predefined or customized views to be printed directly or to be saved as a PDF.
The data is stored automatically on the computer in the PATIENT EXPLORER or on the doctor’s offices’ server.
Yes, the examination with the CARDIOLOGIC EXPLORER is entirely non-invasive. Similar to the 12 Lead Rest ECG, the electrodes will be attached to the upper body and record the potentials of the heart.
