Thanks to evismo-CardioFlex, you receive a quick diagnosis. The lightweight, waterproof sensor is comfortable to wear.

The CardioFlex service allows for a diagnosis the first time it is applied.

You wear the super light, waterproof, unobtrusive and hardly perceptible evismo sensor as long as necessary, but as short as possible, until the diagnosis can be made. The monitoring duration is individually adapted to you - from a few hours to several days or weeks, if this is necessary for a correct diagnosis. Multiple applications are no longer necessary.

The evismo specialists remotely access your ECG data on a daily basis and analyse whether sufficient clinically relevant data is available. As soon as a diagnosis can be made, you will be instructed to remove the sensor.

You will receive your diagnosis and therapy at your next doctor’s appointment.

The costs are covered by your basic health insurance.

The electrocardiogram (ECG)

The electrical activity of your heart (ECG) is continuously measured and stored by the sensor via the electrodes. The data allows the cardiologist to assess whether your heart is functioning properly.


What you should know about cardiac arrhythmias

A heart rhythm disorder is a disease in which the heart beats too fast, too slowly or irregularly. Rhythm disturbances can occur daily, weekly or less frequently. The ECG measured by the sensor shows your doctor when which disturbances occur.

The most common symptoms of cardiac arrhythmias are:

  • palpitations
  • heart flutter or heart stumble
  • fainting, almost fainting or dizziness
  • shortness of breath
  • fatigue
  • chest pains

The most important cardiac arrhythmias

Vorhofflimmern ist die häufigste Atrial fibrillation is the most common cardiac arrhythmia. It is an irregular, fast heartbeat that causes the upper chambers of the heart to tremble irregularly. Atrial fibrillation can amongst other things result in palpitations or chronic fatigue and increase the risk of stroke. Atrial fibrillation can usually be treated well.

A very slow heartbeat (less than 60 beats per minute) is called bradycardia. Doctors call an abnormally fast heartbeat tachycardia - reaching at least 100 beats per minute. Both these cardiac arrhythmias can also be treated well when detected.


Answers to frequently asked questions

Wear the ECG sensor as long as prescribed by your doctor or until the end of the measurement is indicated on the app (on the supplied phone).

The sensor is waterproof. Do not use soap or body cream in the area of the electrodes.

To ensure good signal quality, replace the electrodes every 4 days and the patch after 7 days or as needed.

Remove the electrode pads that stick to the body. These can be thrown away. Wash the skin, additionally clean it with alcohol (you will find alcohol swabs in the box), let it dry briefly and stick on the new electrodes. The position of the pads may vary slightly.

The sensor is recording when a green light on the sensor flashes slowly.

As soon as the diagnosis can be made, the end of the measurement is displayed on the supplied phone.

Your attending physician will discuss the diagnosis and treatment with you.

Your doctor will be happy to show you the ECG and discuss it with you.

The app will tell you when to charge. Or if you hear a constantly recurring beep from the sensor, the battery is almost empty. Disconnect the sensor from the cables and connect the sensor to the power supply using the Micro-USB charging cable. A blue light flashes. You know that the sensor is fully charged again when the blue light on the battery symbol lights up continuously. A full charge takes about 1.5 hours. Now simply reconnect the sensor and press the Start button.

Briefly pressing the start button switches the device on.

Pressing the start button for a longer time (5 seconds) switches the device off. You should only do this at the End of the monitoring.

Our experience shows that this is not a problem.
