CardioSecur – a smart solution for sensitive hearts


Finally peace — finally time for all of the things that until now there wasn’t enough time for. Then suddenly one year later – atrial fibrillation. At first it occurred rarely, then more and more often. A (well known) journey of suffering started. I can still read and interpret ECGs, but I am not a cardiologist nor am I an electrophysiologist who can detect subtle changes on an ECG. After my own internet research and advice from my general practitioner I underwent my first pulmonary vein isolation. However, I still had a few attacks. Then I had a second ablation – and now I wait. Is it over, or will the attacks occur again?

A common problem for all patients with rhythm disorders: when disturbances present, the cardiologist requires a 12-lead ECG to make a diagnosis. However, when going to the doctor or hospital, the disturbance is often gone, and the ECG is therefore negative (normal).

Uncertainty remains. What should I do? Could the next attack be dangerous? How should I react when symptoms are present? Over a year ago I participated in a telemedicine program from the Heart and Diabetes Center in Bad-Oeynhausen. I received a mobile ECG (also 12 lead), which was to be used in the situation of a rhythm disturbance so that an ECG could be recorded. The data was then transmitted by phone to an emergency department within a hospital. The problem, however, is that although one clearly perceives symptoms, many incidents (i.e. episodes of extrasystole) are relatively insignificant. The data transfer by telephone also always had problems. This causes ones to not trust sending an ECG, as he fears that he will be seen as a hypochondriac.

I was therefore searching on the internet for a  “smart solution” that would give me, as a patient with a rhythm disorder, information about if the episode is harmless or serious, and which type of disturbance is present. The research took quite some time. There are many approaches to a solution (in particular hardware) for mobile ECG recording, but very few that are useful and helpful to the patient in his own personal environment.

At the MEDICA conference in 2015 in Düsseldorf I found it. At the CardioSecur stand I was advised extensively and I immediately bought a device.

The system is self-explanatory and has the following advantages for rhythm disorder patients:


  1. I can use it in my daily life anytime in connection with my iPhone or iPad (also when traveling in another country).

  2. After comparison to a reference ECG I receive immediate information about if the disturbance is harmless or if emergency treatment is required (I don’t need to run hastily to the doctor or hospital anymore only to find out that it was really only a few beats of extrasystole and not atrial fibrillation or flutter).

  3. With the Pro device I can record a full 22-lead ECG (as documentation for the doctor) and via the automatic interpretation, I receive additional information that is helpful, as I no longer have my daily practice.


The combination of security (the device tells me what is going on) and documentation (I have an compelling ECG for the physician in case of an emergency) makes the life of one with atrial fibrillation or flutter much easier. I send my ECGs to my cardiologist per email whenever I am of the opinion that they could have an implication on my further treatment.

I have recommended CardioSecur to many friends and acquaintances that also suffer from heart rhythm disorders, and were so hesitant to even go on a vacation. I have showed CardioSecur Pro to both my internist as well as my cardiologist at the heart center in Bad-Oeynhausen. We have compared the ECG leads of CardioSecur with those of a standard clinical device—the physicians were surprised by the quality of CardioSecur.



CardioSecur is a really “smart solution” – particularly for rhythm disorder patients, who often live with anxiety, while they clearly perceive cardiac symptoms but don’t know if and how they should react.

I personally have been living relatively carefree since I have been using CardioSecur. I have not had atrial fibrillation attack for three years now. When I occasionally feel palpitations, I attach the electrodes, and the signal almost always tells me that treatment is not required. Although I can avoid visits to the doctor or hospital, I pay for the device myself, which I do as it is really valuable for my health.

I now always have CardioSecur with me when I am golfing, after a few cardiac incidents recently occurred on the golf course. A quick ECG was very helpful in deciding if an ambulance should be called or not.

All in all, a great device with good service. Many thanks to the whole team—keep it up!
