Global Monitoring
Hardware and software system for telemetry
The Astrocard® Telemetry Global Monitoring hardware and software system for telemetric ECG recording is designed for wireless, remote, continuous real-time electrocardiogram monitoring over extended periods of up to 30 days.
As with conventional Holter monitoring, the patient wears a dedicated ECG recorder that acquires a 3-lead ECG. The recorder’s built-in module transmits the ECG over mobile networks to a dedicated cloud server, where it is stored. It can then be sent to a computer for analysis and to physicians’ mobile phones (iOS and Android) for recording-quality control.
During monitoring, the patient can move freely within mobile network coverage. If mobile connectivity is unavailable, the recorder stores the ECG in its built-in memory and uploads it to the cloud when connectivity is restored.
Telemetry monitoring therefore provides:
- High-quality, continuous 3-lead ECG recording for up to 30 days, with the patient replacing disposable electrodes under physician supervision
- Diagnosis of infrequent conditions associated with cardiac arrhythmias, including detection of asymptomatic atrial fibrillation
- The option to terminate monitoring early when a diagnostically significant event occurs
Treatment monitoring and postoperative follow-up:
Adjustment
Adjustment of antiarrhythmic drug therapy
Follow-up
- Monitoring of patients with chronic heart failure.
- Follow-up after arrhythmia ablation
Remote monitoring
The patient does not need to attend the clinic. Monitoring and record analysis can be performed independently of each other.
Monitoring
Monitoring of patients with implantable cardioverter-defibrillators or cardiac resynchronization therapy defibrillators
Patient ECGs recorded during monitoring at the central station can be analyzed as standard 24-hour (Holter) monitoring recordings, with the following capabilities:
ECG review and presentation
- Review of 2–3-lead or 12-lead ECGs
- Presentation of analysis results as charts and tables
Automatic ECG analysis and classification
- Automatic classification of ventricular complexes by morphology
- Automatic analysis of ventricular and supraventricular arrhythmias, including atrial fibrillation, after expert physician review of QRS complex types
- Manual correction of automated analysis results
ST-segment and ischemia analysis
- ST-segment trend analysis
- Automatic calculation of heart rate, RR and ST trends (for all channels)
Rhythm and variability analysis
- Calculation of spectral and time-domain heart rate variability parameters over 24 hours, for each hour of the recording, and for any 5-minute interval
- Analysis of arrhythmia frequency
- Heart rate turbulence analysis
ECG intervals and morphology
- Calculation of the QT interval at the apex and end of the T wave (QTa and QTe)
- Analytical (regression equation) and graphical calculation of the relationship between QT and RR intervals over 24 hours
- P-wave analysis, including determination of the PQ interval and analysis of P-on-T events (PTAFDEG® algorithm)
- QRST alternans analysis
Specialized algorithms and events
- Automatic detection of pacemaker spikes and analysis of the function of major types of implanted pacemakers
- Detection of nocturnal apnea episodes
