Our expertise in R-peak triggering

09/02/2020

ECG reading is one of the basic functions of medical diagnosis and therapy. In this regard, the analysis and interpretation of ECG signals using algorithms is becoming increasingly important. In particular, the striking QRS complex with the R-peak is the basis for many medical applications. Corscience has been developing and perfecting algorithms and solutions for time-critical R-peak triggering for many years.

Our ECG board EMB1/3 (ECG Micro Board) is optimized in terms of size and power consumption, making it ideal for use in mobile devices. The integrated R-peak detection is output not only via the hardware but also via the software. This makes the module the ideal technical basis for developments with R-peak triggering, which can be adapted to individual requirements by Corscience. We’ve been able to successfully implement applications for the following medical fields in recent years.

Muscular Counter Pulsation (MCP)

In MCP, peripheral muscle groups on the legs are stimulated with electrical impulses and rhythmically contracted exactly at the start of early diastole. This supports venous return, making it an effective therapy for heart failure. The precise synchronisation of the muscle contractions with the patient’s R-peak is crucial for the functioning of MCP.

Cardioversion

External cardioversion is intended to end cardiac arrhythmia and return the heart to its normal rhythm (sinus rhythm). With cardioversion, a current surge triggered by the R-peak is delivered to the heart and the activity of the heart muscle cells is resynchronised.

Imaging

With imaging, ECG triggering can be used to control the recording timing. For example, the automatic R-peak triggering ensures that certain parts of the image are always acquired at the same time within the cardiac cycle.

Mechanical cardiovascular support

“Mechanical circulatory support systems” is a generic term for systems that support the blood circulation. The term therefore includes devices for heart (e.g. VAD, IABP) and cardiopulmonary support (e.g. ELCS/ECMO). Our ECG technology and algorithms are used in these applications to synchronise (trigger) the artificial pumps with the patient’s own cardiac cycle – this relieves the strain on the circulatory system and, consequently, the heart that has already been damaged.
