DuoEK S ECG Monitor

DuoEK S Personal ECG Monitor

DuoEK S Personal ECG Tracker for Home Use

DuoEK S is a handheld wireless ECG monitor with Bluetooth for personal use at home. Used with free ViHealth app, DuoEK S enables you to monitor and review your ECG in real-time in the comfort of your home. DuoEK S is conveniently rechargeable via micro USB cable supplied. DuoEK S ECG Monitor can be used stand-alone or with the ViHealth app. ViHealth app is free and available from Apple Store for the iOS and Google Play for the Android devices. ECG recordings can be easily shared with healthcare professionals.  

DuoEK S does not provide medical diagnosis and does not replace consultations with qualified medical professionals. DuoEK S is a ECG monitor, not a diagnostic device. You must consult your doctor to assess your cardiac health and provide a medical diagnosis and treatment.      

DuoEK S and the ViHealth app are compatible with smart devices (i.e. iOS and Androids)

  1. iOS 9.0 or above
  2. Android 5.0 OS or above  

Using DuoEK S with ViHealth app

When DuoEK S is paired with the ViHealth app, the real-time waveform can be seen on the app during ECG measuring, whilst the measurements are transmitted automatically to the app for storage and analytical reviews of historical measurements.

DuoEK S as stand-alone ECG monitor 

When used stand-alone, the recorded measurements are stored in the internal memory of the monitor up to the total of 20 minutes duration. When 20 minutes of recorded measurements is exceeded, the DuoEK S will overwrite the oldest data with the latest measurements. To avoid loss of recorded measurements, you should transfer the measurements to your smart device (i.e. mobile phone or tablet.)          

Taking ECG measurements with the DuoEK S

DuoEK S Personal ECG Monitor supports 3 methods of taking ECG recordings. It is up to you to select the most convenient or preferred option. Each measurement must take a minimum of 30 seconds and no more than 5 minutes as the monitor stops the measuring automatically at 5 minutes.

3 methods to take ECG recordings using the DuoEK S 

  1. Lead 1 method = Hand to Hand: Hold the right electrode on the DuoEK S with your right thumb and the left electrode with your left thumb. If this method produces a weak signal, it is best to use Lead 2 (see below).
  2. Lead 2 method = Right Hand to Left Leg: Hold the right electrode on the DuoEK S with your right hand and touch the skin on your bare left leg on the inner side just above the knee with the left electrode. The Lead 2 normally produces a good view of the P wave and is frequently used to record the rhythm wave. Lead 2 should be used preferentially, if you cannot get a strong signal, when using the Lead 1 method.   
  3. Chest Lead method = Right Hand to Chest: Hold the right electrode on the DuoEK S and position the monitor across the front of your chest just below the pectoral chest muscles. Hold the monitor with electrodes closely on your chest.
