What do we call WIWE?

WIWE consists of two parts: WIWE itself is the medical device with which you take the recording, and the application set up on your mobile/ tablet. 

What can WIWE be used for?

WIWE can be used with a mobile application to record single-channel electrocardiogram (ECG).

The recording itself takes only 60 seconds.

The application is capable of showing the entire recorded ECG wave. Furthermore, it can detect heart rate fluctuation and, in severe cases, atrial fibrillation (AF) that is shown by the ventricular heterogenety (VH) results.

It can measure the Blood oxygen level and the Heart rate.

It has other built-in functions, such as a pedometer and a calorie counter.

Can WIWE predict a heart attack?

No, WIWE is not meant for predicting heart attacks. It is capable of calculating the risks of a possible Atrial Fibrillation and Ventricular Heterogenity, which can lead to a Stroke or a Sudden Cardiac Arrest.

What is the difference between a heart attack and a sudden cardiac death?

Sudden Cardiac Death is an unforeseen, natural death caused by Sudden Cardiac Arrest, emerging independently of age and other conditions. At the same time, heart attack is myocardial necrosis caused by circulation disorder.

To detect heart attack multi-channel electrocardiogram is need to be done simultaneously. Heart attack is not detectable by single-channel electrocardiogram (ECG) which is the main function of WIWE.

How accurate is WIWE?

WIWE detected Atrial Fibrillation  with more than 98% accuracy out of 10 000 measured ECG waves.

What functions can be offered for people interested in fitness and sport? For what can they use the measured data?

There is a built-in pedometer, capable of counting steps, distance and burnt calories. To measure this latter one there is a built-in acceleration sensor.

Using the measured data charts can show you broad picture of your activity, not to mention the interesting milestones for motivation.

Is my data stored safely?

The application saves the results and stores them on your phone. No data will be sent or stored anywhere else, so only you can share them, if you want to.

How much data can be stored?

The amount of data stored depends on the capacity of the smartphone or tablet.

One user profile can contain 1000 ECG recordings.

Will this work with my tablet or smartphone?

WIWE works with a couple of Android and iOS smartphones and tablets.

Where can I get more information on the warranty, service, batteries, storage and disposal of WIWE?

You can get more information concerning these topics either in the applications info section or on the website through the following link here.

How often do I need to recharge WIWE?

When WIWE is fully charged - in this case 4 green LEDs are glowing -  it can take approximately 100 recordings.

When there are 2 or less leds glowing on WIWE, you need to charge it.

You can charge the device using a microUSB cable (included). Whilst charging, one red LED will glow until WIWE’s fully charged.

Can WIWE get out of order? How will I recognize when it has gone wrong?

The glowing of the red error signaling LED indicates that the ECG signals are not stable or low. In this case please repeat the recording. 

What happens if I have dropped down WIWE? How fragile is it? Is the surface scratch-resistant?

From this point of wiew WIWE requires the same carefullness as your smartphone or tablet which runs the application.

Do I have to clean the surface of WIWE?

The device is not water-proof, it can be cleaned with soft, clean cloth.

Questions by health experts

What is the connection between the state of the heart muscle and venticular heterogenity?

In our case ventricular heterogenity is the diversity of the ventricle’s heart muscle cells’ bioelectrical property. This heterogenity is present even in healthy cases as predetermined (basically tense connection between the cells). But, in pathological cases the heterogenity of the cells grow and the aligned working of the heart muscle cells becomes worse. This calls forth the lability of the bioelectrical phenomenons. This instability increases the risk for developing dangerous ventricular arrhythmias, hereby increasing the risk for Sudden Cardiac Arrest.

What clearances does WIWE have?

WIWE will have Class IIa CE mark as a medical device soon.

Getting the FDA clearance is in progress.

Can WIWE replace a 12-lead ECG?

No, WIWE records single-channel ECGs and is not intended to be a replacement for a 12-lead ECG.

What is the difference between sudden cardiac death and sudden cardiac arrest?

Sudden Cardiac Arrest is the unexpected stop of the beating of the heart. Because of this, the blood can’t reach the brain and other vital organs in the body. If this condition doesn’t get treated within minutes, it causes death, which is called Sudden Cardiac Death.

Is my patient's date safe?

The data recorded will be stored on the users smartphone or tablet.

Is there any kwown medical contraindications for the use of WIWE?

No, there are no known medical contraindications which could prohibit the use of WIWE.

Do I still need to see the doctor if I use WIWE?

Yes, you still need to see the doctor. WIWE can’t replace medical care, it enables you to check your hearts functioning.
