CONTEC TLC9803 3-Lead 24-Hour ECG Holter Recorder

Introduction

The CONTEC TLC9803 3-Lead 24-Hour ECG Holter is a robust ambulatory monitoring system designed to continuously record electrical activity of the heart over a full day. It helps clinicians detect intermittent arrhythmias, assess heart rate trends, and analyze heart rate variability (HRV) in a real-life setting. Compact, battery-powered, and supported by PC analysis software, the TLC9803 combines portability with clinical-grade features. 

Features

• 24-Hour Continuous Recording
  Captures ECG data round-the-clock to detect transient events. 

• 3-Lead Input
  Supports three ECG leads (commonly I, II, III or other configurations). 

• Arrhythmia & HRV Analysis
  Built-in modules analyze arrhythmias (e.g. PAC, PVC, AF) and heart rate variability over 5-minute, 1-hour, and 24-hour periods. 

• “HRT” & T-Wave Alternans
  Offers heart rate turbulence (HRT) and T-wave alternans evaluation to help stratify risk of malignant arrhythmias. 

• Sleep Breathing Pause Prediction
  Includes a unique analysis function to predict sleep breathing pauses (sleep apnea risk).

• Flexible Channel Selection & Templates
  Choose which lead to analyze, use multiple templates (atrial, ventricular, long interval, etc.), and define custom modules.

• Pacemaker Analysis Capability
  Detects and analyzes various pacing modes (e.g. DDD, VVI, AAI) and pseudo-fusion events.

• Compact & Lightweight
  Device dimensions: 111 × 60 × 25 mm, weight approx. 105 g (without batteries). 

• Battery Powered & USB Interface
  Powered by two AA batteries. Data transfers via USB 2.0. USB cable included. 

• Low Noise & High Sensitivity
  Noise ≤ 30 μV, CMRR ≥ 60 dB, minimum measurable signal ~50 μV p-p. 

Benefits & Use Cases

Benefits

• Detects intermittent arrhythmias that may not appear during a short ECG.

• Provides rich diagnostic data like HRV, T-wave alternans, and HRT for deeper cardiovascular risk assessment.

• Lightweight and battery-powered, enabling true ambulatory monitoring.

• Flexible software tools allow clinicians to customize analyses per patient.

• Useful in outpatient, cardiac rehabilitation, and remote monitoring settings.

Use Cases

• Patients with unexplained palpitations, dizziness, or syncope.

• Monitoring after myocardial infarction to assess risk or recovery.

• Evaluation of drug efficacy or adjustment in arrhythmia therapies.

• Long-term follow-up in cardiology clinics or remote diagnostics.

Comparison with Alternatives

FAQs

Q1: Can I shower while wearing this Holter?
No. Most Holter devices, including this model, are not waterproof. The patient should avoid water exposure as it may damage electrodes or the recorder.

Q2: How often should batteries be changed?
Use fresh, high-quality AA batteries before each recording session to ensure full 24h operation.

Q3: Does the software support report printing?
Yes — it includes one-key print functions and flexible report generation (5-min, 1h, 24h) with rhythm templates. 

Q4: Can I analyze only one lead if others are noisy?
Yes — the system supports flexible channel selection so you can choose which lead to analyze. 

Q5: Is there warranty support?
Yes. Most Indian distributors offer 1 year warranty on the hardware.
