The Tricog VCardia is a portable, clinical-grade 12-lead electrocardiography system designed for recording and evaluating the electrical activity of the heart. It combines a compact ECG acquisition unit with an Android-based application to create a digital workflow for patient registration, ECG recording, report generation, and sharing.

The VCardia is designed for resting ECG examinations in adults and captures the heart's electrical activity simultaneously through the standard 12-lead configuration. Its portable design allows ECG testing to be performed across clinics, hospitals, diagnostic centres, and other healthcare environments where a compact cardiac assessment system is required.

12-Lead ECG Acquisition

The VCardia captures a standard 12-lead ECG using 10 electrodes: four limb electrodes and six chest electrodes. The resulting 12 leads include I, II, III, aVR, aVL, aVF, V1, V2, V3, V4, V5, and V6. Simultaneous acquisition provides a comprehensive representation of the heart's electrical activity from different anatomical perspectives. These recordings can be used to evaluate heart rate, rhythm, conduction intervals, and ECG waveform characteristics as part of a clinical cardiac assessment. The system follows recognised ECG standards, including IEC 60601-2-25, and supports AHA and IEC ECG standards.

Digital ECG Recording

VCardia connects to an Android smartphone or compatible Android device through a USB/OTG connection. The VCardia application guides the operator through patient information entry and ECG acquisition. The basic workflow involves:

• Connecting the VCardia unit to an Android device
• Connecting the ECG patient cable
• Attaching the four limb electrodes
• Positioning the six chest electrodes
• Entering patient details through the application
• Capturing the resting 12-lead ECG
• Reviewing and processing the recorded ECG
• Printing or sharing the report digitally

This approach replaces a conventional paper-dependent workflow with a compact digital system.

ECG Measurement Parameters

The VCardia system records the electrical signals required for standard resting ECG analysis. Its documented measurement parameters include:

• Atrial rate
• Ventricular rate
• PR interval
• QRS duration
• QT interval
• QTc interval
• P axis
• R axis
• T axis

These measurements provide quantitative information that can assist qualified medical professionals in assessing the recorded ECG alongside the patient's clinical history and other findings.

ECG Signal Processing

VCardia incorporates signal-processing functions designed to support ECG acquisition and waveform presentation. The documented system provides selectable gain settings of 5 mm/mV, 10 mm/mV, and 20 mm/mV, along with recording speeds of 25 mm/s and 50 mm/s.

The system also incorporates baseline-drift removal and muscle-artifact filtering. Its documented frequency response extends from 0.5 Hz to 150 Hz, while the common-mode rejection ratio is specified at 110 dB. These technical features support the acquisition and presentation of ECG signals for clinical review.

Pace Pulse Detection

The system includes dedicated pace-pulse detection functionality. Pace pulses meeting the system's defined amplitude and duration conditions can be identified and marked during ECG acquisition. This feature can help draw attention to pacing-related electrical signals within the recorded ECG and can be considered during interpretation by appropriately trained healthcare professionals.

AI-Assisted ECG Analysis

The VCardia ecosystem includes AI-based ECG analysis as an available service. Tricog states that its algorithms can identify more than 140 cardiac conditions from ECG recordings. Depending on the selected service configuration, ECGs can receive AI-generated analysis and, for specified cases, review by Tricog's medical team. These services are separate from the core ECG acquisition hardware and depend on the reporting plan and connectivity available to the user. AI-based analysis is intended to support clinical workflows and does not replace assessment by a qualified medical professional.

Digital Reports and Wireless Sharing

One of the major features of the VCardia workflow is digital ECG reporting. Recorded ECG information can be processed through the VCardia application and converted into a report that can be stored, viewed, printed, or shared electronically. The system supports wireless report sharing, while the VCardia unit also provides compatibility with printers through its available connectivity options. Digital reports can facilitate communication between healthcare professionals and can be useful when ECG findings need to be transferred from one location to another.

Cloud-Connected Cardiac Workflow

VCardia is designed to support connected ECG workflows. Depending on the selected Tricog service, ECG records can be transmitted for remote analysis and reporting. This connectivity can be particularly useful for healthcare environments where specialist cardiac interpretation may not be available at the location where the ECG is recorded. Tricog's platform provides access to remote reporting services, with critical ECG workflows designed to support rapid communication. The cloud and remote-reporting features depend on the applicable VCardia service plan and connectivity.

STEMI Alerts and Critical ECG Workflows

The VCardia ecosystem includes a STEMI alarm feature for critical ECG cases. Tricog describes its connected service as providing alerts for critical cases and remote medical support. This type of workflow can help healthcare teams communicate potentially time-sensitive ECG findings more efficiently. The ECG itself remains a diagnostic recording that must be interpreted by qualified healthcare professionals in the context of the patient's symptoms and clinical condition.

Portable Design

The VCardia VC100 is designed as a portable ECG device. The documented physical specifications list dimensions of approximately 200 × 200 × 73 mm and a weight of approximately 580 grams. Its compact construction allows it to be transported between examination areas without the footprint of a conventional full-size ECG workstation. The system is powered through its connected setup and is designed to work with Android devices, making the display and user interaction dependent on the compatible smartphone or tablet used with the unit.

Technical ECG Specifications

The documented VCardia specifications include:

• ECG type: 12-lead resting ECG
• ECG sampling rate: 1000 Hz
• Pace detection sampling rate: 16 kHz per channel
• Gain: 5, 10, and 20 mm/mV
• Recording speed: 25 and 50 mm/s

• AC filter: 50/60 Hz
• Defibrillation protection: ±5000 V, 360 J
• Operating system: Android-compatible workflow
• Patient population: Adults for the documented VC100 configuration

These specifications describe the ECG acquisition capabilities of the documented VCardia configuration.

Clinical Applications

A 12-lead resting ECG can form an important part of cardiovascular assessment. VCardia can support ECG recording in a variety of clinical settings, including:

• Routine cardiac screening
• Assessment of heart rate and rhythm
• Evaluation of suspected arrhythmias
• Assessment of ECG changes associated with cardiac conditions
• Pre-procedure cardiac evaluation
• Follow-up ECG examinations
• Emergency and critical cardiac assessment
• Diagnostic-centre ECG services
• Remote and connected cardiac-care workflows

The specific clinical interpretation of an ECG should always be performed by an appropriately qualified healthcare professional.

Integrated Digital Cardiac Assessment

The Tricog VCardia combines standard 12-lead ECG acquisition with a portable hardware design and Android-based digital workflow. Simultaneous lead acquisition provides the electrical information required for conventional resting ECG examination, while automated measurements and digital reporting help organise the resulting data. Its connected ecosystem can additionally support remote reporting, AI-based analysis, critical ECG alerts, and digital report sharing when the relevant Tricog services are enabled.

At Molecular Diagnostics and Therapy, the VCardia ECG system provides a compact approach to routine electrocardiographic assessment, combining clinical-grade 12-lead recording with a modern digital workflow for acquisition, analysis, reporting, and communication.
