Astrocard® – CardioEP II

Nonfluoroscopic system for intracardiac electrophysiology studies

The system is designed in accordance with the recommendations of the Expert Committee of the Ministry of Health of the Russian Federation and the Russian Academy of Medical Sciences on implantable antiarrhythmic devices and electrophysiology.

Support for Fast Mapping technology for rapid reconstruction of 3D cardiac models

Capability to work with all catheter types

Fusion of the electroanatomical cardiac model with 3D models derived from computed tomography or magnetic resonance imaging

Automatic detection of cardiac cycles used for mapping

Automated support for pace mapping (correlation map generation)

Generation of isochronal maps, activation propagation maps, voltage maps for visualizing myocardial fibrosis zones, and maps of local myocardial contractility

Support for mapping with any multipolar catheters

Visualization of ablation zones

Designed for intracardiac electrophysiology studies using endocardial cardiac mapping and programmed cardiac electrical stimulation. Fully compatible with equipment used for catheter ablation.

The equipment included in the system provides:

Recording and visualization of surface ECG signals and intracardiac electrograms
Ablation of arrhythmogenic areas in the heart using the included RF ablation generator
Electrical stimulation of various regions of the heart using the included cardiac stimulator

Exercise testing with atrial stimulation to detect myocardial ischemia
Determination and display of intracardiac catheter electrode positions
Generation and visualization of cardiac electrical activation maps

Recording

The system can simultaneously record surface ECG in standard leads and intracardiac electrograms through differential or unipolar channels (up to 128 channels). It can also record readings from invasive pressure sensors.

Recorded data can be displayed in real time or reviewed retrospectively using the number of channels selected by the user.

All channels have built-in protection against the RF ablation generator. User-programmable digital filters are also available for displaying the surface ECG and recorded intracardiac electrograms, supporting high-quality signal recording.

During the study, both the current ECG (and electrograms) and any preceding segments of the recording can be printed

All study data are saved for subsequent review and archiving

Cardiac stimulator

The system includes a three-channel stimulator that supports programming of all main types of cardiac electrical stimulation used in clinical electrophysiology studies.

Stimulation can be delivered using either standard rectangular pulses or biphasic pulses. During stimulation, impedance between the stimulating catheter electrodes is monitored.

RF ablation generator

The system includes an RF ablation generator compatible with most existing ablation catheters. During ablation, impedance is monitored continuously and the temperature in the treatment area is controlled automatically.

Analysis

The study recording is reviewed in a multichannel display at the selected scale, with smooth or stepwise navigation through the recording. Electrical stimulation markers and parameters are shown, together with complete information on RF ablation applications performed during the study.

To facilitate selection of recording segments of interest, data are also presented as trends (heart rate, etc.) for the entire study. Time intervals and amplitude characteristics are measured with high accuracy using dedicated cursors.

During review, any recorded channel or combination of channels can be filtered at user-defined frequencies without altering the original recording.

The system stores all completed study data in a dedicated database. Additional equipment can also be supplied for working with study recordings outside the sterile area of the operating room.

Map generation

The system software and hardware determine and visualize the position of each endocardial catheter electrode.

Coordinates are determined for all inserted catheters, and any catheter type can be used for mapping (i.e. dedicated high-cost catheters are not required, unlike with some other navigation systems).
