`1PCS Contec TLC9803 Portable 24‑Hour Dynamic ECG Holter Recorder Monitoring System`

IntroductionTLC9803 Dynamic ECG Holter System is equipped with 3‑lead electrodes, which is capable of continuously recording ECG waveforms over a 24‑hour monitoring period. Recorded data can be imported and analyzed via supporting PC software. This device is intended for use in medical institutions and community‑level healthcare departments.Main FeaturesThe recorder stores ECG data continuously during the full‑day 24‑hour monitoring cycle.Arrhythmia analysis supported by MCSSTM and TMCSTM algorithms helps streamline workflow for medical practitioners.Built‑in over 10 analysis templates, including premature atrial contraction, premature ventricular contraction, long pause, atrial fibrillation and more. Custom‑editable modules are also available to assist clinicians in reviewing pathological waveforms.Flexible channel‑selection function allows users to set any available lead as the primary analysis channel.Multiple analysis modes are offered for atrial fibrillation evaluation; physicians may run either full‑cycle or segmented automatic or manual analysis for comprehensive waveform review.Advanced pacemaker analysis supports waveform evaluation for common pacemaker modes such as AAI, VVI, DDD, etc.Pre‑configured pacing analysis templates cover dual‑chamber pacing, atrial pacing, ventricular pacing, ventricular pseudofusion, ventricular asynchronous pacing and other common pacing conditions.Quick‑review function enables users to access single‑lead or full‑lead ECG records from any selected time segment.Heart rate variability analysis is available for 5‑minute, 1‑hour and 24‑hour monitoring sessions.One‑click report printing function for fast and convenient report output.Comprehensive patient‑case data‑management system.Supports waveform analysis related to sleep‑disordered‑breathing ECG data for clinician reference.Provides HRT waveform analysis data for physicians’ clinical evaluation.Supports T‑Wave alternation waveform analysis for clinical assessment by qualified medical professionals.Technical SpecificationsLead: 3‑leadRecording Duration: ≥ 24‑hourPower Supply: 2 × AA alkaline batteriesData Interface: USB 2.0Sampling Resolution: 24‑bitSampling Frequency: 250HzDynamic Range: 10mVInput Impedance: ≥ 10MΩCommon‑Mode Rejection: ≥ 60dBGain Accuracy: The maximum output amplitude error shall be ±10% across all gain settings.Gain Stability: After one‑minute warm‑up, gain drift shall not exceed 3% over a 24‑hour monitoring period under stable ambient conditions.System Noise: ≤ 50µVp‑pMultichannel Crosstalk: ≤ 0.2mVFrequency Response: Amplitude response for sine‑wave signals from 0.05Hz‑40Hz falls within +3dB /‑3dB relative to the response at 5Hz.Minimum Detectable Signal: 50 µVPacemaker Pulse Detection: Supports recognition of pacemaker pulsesTiming Accuracy: Total time error within 24‑hour recording ≤ 30sAccessories Included1 × Lead cable set1 bag of ECG electrodes1 × USB data cable1 × Software package1 × Carrying bag1 × User manualPhysical ParametersDimensions: 111mm (L) × 61mm (W) × 25mm (H)Weight: Approx. 105g (excluding batteries)Note: This equipment is intended for clinical waveform‑recording use only.
