Tips for Successful 24 hour Holter Monitoring 24 hour holter ecg

Using CardioMera 24 hour holter monitor is simple. For programming the device you will need a properly configured CardioVisions software, a fully charged battery, a memory card inserted into the device and a USB cable to connect the device with the PC.

Start CardioVisions software and select CardioMera 24 hour holter monitor from the device types. Click on Device/Programming device.

  • Enter new patient data or select patient from the database.
  • Apply the the electrodes to the patient.

Online electrode check is available in CardioVisions 24 hour holter monitor.

  • Create and send the monitoring plan

In case of CardioMera 24 hour holter monitor, the software enables to write the monitoring plan directly to the memory card, which makes it possible to create the plan in the absence of the devices as well.

  • Apply the device to the patient and give the patient diary to note events, symptoms, observations and complaints occur during the monitoring period.

After the monitoring period you will need a card reader to read data from CardioMera 24 hour holter monitor.

Tips for the Proper Electrode Placement

Each 24 hour holter monitor can be used with 3 to 7 individually exchangeable ECG lead cables. Multi-channel recording improves the chance to avoid misdiagnosed recordings, reduces the chance to miss something important due to noise, electrode problems or improper "viewing angle". See the standard ecg cable colour codes and recommended positions in the following table.

ElectrodeColourRecommended position
EU USA
A+ green red left anterior axillary line, intercostal space 5
A- red white manubrium sterni
B+ white brown left anterior axillary line, intercostal space 5
B- yellow black right anterior axillary line, intercostal space 5
C+ orange orange left posterior axillary line, intercostal space 5
C- blue blue right sternal border, rib 2
N black green corpus sterni

 In the recommended layout, described in the table above and shown in the figure, the resulting channels will correspond to the most commonly used 24 hour ecg holter monitor leads as follows:24 hour Holter Monitor Electrode Placement

  • channel A = CM5
  • channel B = CC5
  • channel C = inverse Nehb J (if applied)

Preparing the patient and the electrodes

  • Clean and possibly depilate the chest
  • Attach disposable electrodes to ecg lead cable connectors
  • Apply the electrodes to the proper positions
  • Create stress-release loops with each cable

It is advised to create a stress-release cable loop on each lead cable, close to the electrode (about 5-10 cm) and fix it to the patient's skin with non-allergic adhesive tape. Loop-protected cables will reduce movement disturbances.

It is recommended to check electrode placement in CardioVisions software before an ecg recording session to record the best quality ecg signals.
