The complete Holter Rhythm package Alfa System A712 records the patient's electrocardiogram for 24-48 hours and consists of:

• The digital recorder of ambulatory electrocardiography with 12 channels
• The HolCARD 24W software.

Main features of the recording unit AsPEKT 712:

• Digital recorder of 12-channel ECG signal.

• Patient cable with 10 leads.

• Recording time: 24/48 hours on CompactFlash card.

• Graphical LCD display.

• Real-time clock.

• EVENT button.

• Pacemaker detection.

• Wireless online ECG transmission via AsLINK and infrared IrDA interface.

• Dimensions: 130 x 96 x 30 mm.

Main features of the HolCARD 24W software:

• Fully compatible with Microsoft Windows environment.

• Provides 3 or 12 independent recording channels (depending on the recording unit).

• Automatically detects and classifies arrhythmias based on user-adjustable criteria.

• Reliable morphology recognition algorithm and dynamic classification into groups, allowing quick and efficient confirmation or correction by the analyzing physician.

• Performs analysis of RR interval variability and analysis of heart rate variability in both time domain and frequency domain.

• In the time domain of Heart Rate Variability, parameters-coefficients are calculated as referred to in international literature, with the option of selecting small time intervals for analysis from the entire 24-hour recording. The calculation of these parameters can also be selected.

• In the frequency domain of Heart Rate Variability, spectral analysis is calculated in 3 variable frequency ranges: very low frequency, low frequency, and high frequency. The calculation of these frequencies can also be selected.

• Performs analysis of ST interval in all three channels, with the option to redefine the results after modification of the J and Q points.

• Recognizes and analyzes pacemaker electrocardiogram of single-chamber or dual-chamber pacemakers, providing histograms of intrinsic and paced beats.

• Not available in standard equipment.

• Data analysis time is short (not exceeding 1-2 minutes, depending on the capabilities of the existing computer), and the data analysis printing time is fast and does not exceed 5 minutes for a complete printout (depending on the capabilities of the existing printer).

• Ability to store on the computer's hard drive or on CD, occupying small capacity (ECG signal file: 30-35 MB - Analysis file: 10-15 MB).

• Simultaneous detection of arrhythmia in all three channels.

• Automatic signal calibration in all channels independently ensures the use of the entire available dynamic range.

• Color display of indications.

• Ability to Detect, Review, and Process in qualitative assessment VE, VT, Single SVE, PSVT, Pause, Irregular Rhythm, VT, IVR, Bradycardia and Tachycardia, Couplets, Elevation and Depression of the ST segment, maximum, minimum, and average Heart Rates, artificial segments.

• Reliability control tool for classifying the pulse that makes correction easy and effective.

• Hourly summary in the form of a table of all quantitative results.

• Printing available for all recorded ECG signals.
