ECG Monitor

What this section covers

14 devices in three groups by purpose: 7 electrocardiographs and ECG boxes (acquisition, analysis and report output of the 12-lead ECG signal), 4 multi-parameter monitors (continuous monitoring of ECG, heart rate, blood pressure, SpO2, respiration and temperature) and 3 fetal monitors (fetal heart rate, contraction pressure and fetal movement).

Clinical departments

• Electrocardiographs: outpatient and emergency departments, cardiology, wards, health-screening centres, community health centres.
• Monitors: ICU, operating theatre, post-anaesthesia recovery, emergency, bedside on the ward, intra-hospital transfer and ambulances.
• Fetal monitors: obstetric outpatient clinics, delivery rooms, maternity and child health institutions.

Device types and configurations

Key specifications

• ECG acquisition: standard or Cabrera 12-lead simultaneous acquisition; 8000 Hz sampling rate; frequency response 0.05 Hz to 150 Hz
• ECG performance: common-mode rejection ratio >100 dB; noise level ≤15μVp-p; polarisation voltage tolerance ±600 mV
• Paper speeds: 5 / 6.25 / 10 / 12.5 / 25 / 50 mm/s; sensitivity 1.25 / 2.5 / 5 / 10 / 20 / 40 mm/mV
• Monitoring parameters: ECG, heart rate, non-invasive blood pressure, SpO2, respiration, temperature; invasive pressure, end-tidal CO2 and others can be added
• Data storage: 720 hours of trends, 2 hours of waveforms, 1000 blood pressure readings, 200 alarm events, depending on model
• Networking: wired or wireless TCP/IP; fetal monitors can connect to a central obstetric station
• Fetal monitoring: operating frequency 1.0 MHz, measurement range 50 to 210 bpm, ultrasound intensity below 5 mW/cm²

Where it fits

• Primary care and community: routine ECG examination and follow-up of chronic disease.
• Private clinics and health-screening centres: ECG screening and report issuance as part of health checks.
• Hospital clinical departments: continuous monitoring and transfer in the ICU, operating theatre, emergency department and cardiology.
• Maternity and obstetrics: antenatal examination and fetal monitoring in the delivery room.

How it differs from our other ultrasound ranges

This section covers ECG and monitoring equipment, which serves a different purpose from the ultrasound sections on this site, and the two are not interchangeable: ultrasound devices are used to examine morphology and blood flow, while the devices here acquire ECG signals, monitor vital signs and monitor the fetus. The two are often used together in the same department and are selected separately according to clinical purpose.

Common purchasing questions

Q: How many channels does an electrocardiograph need?
A: For routine outpatient and health-check work, three or six channels are sufficient; where the full 12 leads have to be seen on one screen and long-duration arrhythmia analysis is needed, choose a 12-channel model.

Q: What is the difference between an ECG box and an all-in-one electrocardiograph?
A: An ECG box is used with a computer, which suits settings that already have a computer and ECG software; an all-in-one unit has its own screen and printer and works out of the box.

Q: How many parameters should a monitor have?
A: Six parameters are enough for routine bedside monitoring on a ward; in the ICU and operating theatre, modules for invasive pressure, end-tidal CO2 and similar can be added.

Q: Can the devices connect to the hospital system?
A: Export via USB, SD card and network is supported, and reports can be output as PDF / JPEG / XML; fetal monitors can connect to a central obstetric station. The exact interface depends on the model selected and on the hospital's system.
