InstantCheck can help to detect heart irregularities at an early stage and therefore, InstantCheck can help to prevent worsening of the heart disease by early detection. InstantCheck is an excellent tool for people suffering with atrial fibrillation and other irregular heart rhythm disorders. 

InstantCheck functions as a simple event recorder for people with symptomatic or asymptomatic arrhythmia and those on certain heart medications or after cardio-thoracic surgery. InstantCheck ECG also helps primary care physicians to pre-screen patients with cardiac complaint. InstantCheck ECG is easy to use and there are 2 ways (methods) of use. The first way is to place the thumbs in InstantCheck’s specially designed built in conductive electrodes. The second way is to use external self adhesive ECG electrodes pads connected with the main unit by electrode extension cable.

  1. The first method of using InstantCheck ECG is the simplest as it does not require any electrodes to be placed on the user’s body. There are two specially designed integrated conductive electrodes on the main InstantCheck unit. All you have to do is to place your thumbs on the electrodes and gently press down to record the ECG signal. Your thumbs should not be moistened as the InstantCheck integrated electrodes are designed for conducting with dry thumbs. This method of using the InstantCheck ECG is very fast and can be done anytime and anywhere without any inconvenience.
  2. The second method of using InstantCheck ECG employs external skin electrodes placed on your forearms. The external skin electrodes are connected to the main InstantCheck unit by a special connective cable. This method provides a good option for people who cannot use the thumbs well or find the first method difficult to perform. 

The InstantCheck displays the data in a clear and precise waveform, making the InstantCheck ECG perfect for self testing or home based ECG monitoring of cardiac problems under the supervision of medical professionals.
