Frequently Asked Questions

Using CardioSecur is extremely easy. Receive an ECG analysis, with validity comparable to that from your physician, in just three steps.

To start, record a reference reading (reference ECG) at a point in time when you are free of symptoms. This personalizes your device. Each subsequent reading will be compared with this reference ECG. If changes are present between the two ECGs, you receive a recommendation to act. You also receive an ECG report for each recording, which is saved in your app.

CardioSecur Active is mostly used for the quick and easy clarification of unclear symptoms and for prevention of life-threatening acute events.

In the setting of a known diagnosis, regular control readings can also detect non-symptomatic events and prevent damage to the heart (e.g. heart attack, stroke).

You have two options:

a.     You can link with your physician directly in the app if he has already created a free CardioSecur physician account.

b.     You can display your ECG on the screen of your smartphone when you are with your physician, or you can send or print your ECG.    

Yes, CardioSecur can also be used offline. No matter where you are, you can record an ECG at any time and receive automatic feedback within the app.

A network connection is required to synchronise your user account. Readings that are recorded when offline will be synchronized as soon as you have an internet connection.

On your mobile device: your data is stored in your CardioSecur Active app. The number of ECGs that you can save is depenent upon the storage capacity of your smartphone, and is limited to 10,000 readings.

In your user account: when you are logged in to the app, your ECG readings are synchronized with your user account. The data are saved on secure, proprietary servers, which are physically located in Germany. The servers are regularly audited as part of CardioSecur’s approval as a medical system (according to DIN EN ISO 13485). The management of the data is subject to the strictest data protection regulations (according to the BDSG) and the new EU GDPR (General Data Protection Regulation) for data with special protections (e.g. medical data).

To ensure additional data security, your personal and health data are transmitted separately from each other during the encrypted transfer to the server. Matching your data to your identity is therefore not possible.

By synchronizing your account, your ECG data is backed up twice –once on your smartphone, and once in your user account on the server. If you lose your smartphone, you do not lose your data.

Synchronization also offers the possibility to connect with a registered physician through the app so that your ECG data are made available to him.

Please note: synchronization from iOS to Anroid is currently not possible.

According to law, as a consumer you have the option to revoke your online purchase up to 14 days after the date of delivery. You are responsible for paying the costs for the return of goods. In order to receive a refund, the goods must be functioning and in flawless condition. The original packaging does not need to be intact.    

CardioSecur complies with the standard for electromagnetic compatibility (IEC60601-1-2.2001) for electronic devices in regard to immunity as well as emissions. Nevertheless, you should still take special precautions when using CardioSecur. Do not use devices near CardioSecur that generate strong electric or electromagnetic fields. It is recommended to keep a minimum distance of 2 meters. Distances of less than 2 meters may lead to device malfunction, which may result in distortion of the ECG line.    

If your app is not working, please follow the steps below in the order listed. If your app is still not functioning after performing step 1, move on to step 2.

1.      Close the app and restart it. Merely „hiding“ the app is not sufficient. 2.      Turn your device off and restart it. 3.      Download the newest version of the CardioSecur Active app. 4.      Update the operating system of your smartphone.

If your app works to the point that you are able to view the main menu, please ensure that you are logged in with your user account and that your synchronization is activated (menu – settings – user account).

Typically, pacemakers function either below a minimum or above a maximum heart rate. This means that the pacemaker starts to pace the heart when it is beating outside of the normal range. ECG curves with or without a pacemaker look completely different. For CardioSecur, reference ECGs and control ECGs can be recorded with a pacemaker.  When interpreting results one must take into account if the reference ECG was being paced or not. If both ECGs are not the same (both paced or both not paced), false alarms can present.

The following decision tree can help to understand this:

1.      Reference ECG = normal ECG

Control ECG = normal ECG : normal comparison

Control ECG = pacemaker ECG : Red alarm

2.      Reference ECG = pacemaker ECG

Control ECG = normal ECG : red alarm

Control ECG = pacemaker ECG : normal comparison
