Device to Record Long-Term ECG Signals from Inside the Esophagus
Cardiac arrhythmia are often accompanied by palpitation which a patient may not interpret as a rhythm disorder. To detect such arrhythmia cardiologists need a long-term capturing device for ECG signals.

First we develop an E2coder system consisting of a sensor catheter and a behind-the-ear electronics platform. We investigate the novel ECG signal types that result from esophageal recording and research on their clinical interpretation as well as their signal compressibility. Second, with the acquired novel knowledge we built an ASIC that allows the signal processing to reside in the esophagus as well.
The project develops a recorder that measures ECG signals from inside of the esophagus close to the heart. As compared to existing Holter devices, our ECG recorder is able to capture long-term signals inherently in a much higher quality.
Investigtion and analysis of hardware algorithms for signal processing (for improvement of biomedical ECG monitoring systems), ASIC design
First esophageal ECG signals have been captured with our electronics.
The next steps comprise clinical test series.
