Secondary prevention

In approx. 30% of all strokes, the cause remains unknown despite intensive diagnostics.
It is assumed that half of these so-called cryptogenic strokes are caused by undetected paroxysmal atrial fibrillation.

"SRAclinic®"supports the diagnostic of paroxysmal atrial fibrillation at stroke units and thus increases the detection rate. An algorithm identifies fibrillation episodes timely and fully automatic which enables the clinical staff to take early therapeutic measures to prevent secondary strokes. The performance of "SRAclinic®" has been impressively demonstrated within a clinical study with approx. 500 patients. The detection rate of paroxysmal atrial fibrillation was significantly increased by 40%.

Secondary prevention needs innovation

Besides the needs in the acute care of patients after a stroke, the major objective is the preservation of the vital functions as good as possible. This also includes the prevention of secondary strokes.

In this context there is a substantial gap concerning the diagnosis of paroxysmal atrial fibrillation which has not yet been closed satisfactorily. Fibrillation episodes are overlooked at the surveillance monitor, because it cannot be looked at continuously; the sensitivity of 24 Holter recordings is not sufficient; longer recording times result in an increased time for the analysis, which is not acceptable for economical and practical reasons. This holds also for the daily analysis of the full disclosure ECG from monitor recordings. SRAclinic plays a decisive role in closing this gap.

SRAclinic®: Using SRAclinic®, either the complete ECG from the monitoring is used for the analysis or The ECG is recorded with a conventional Holter for several days. This procedure results in an increased detection rate of previously unknown paroxysmal atrial fibrillation by 40%.

SRAclinic® is a secure, fast and economical technique which can be easily applied at stroke units. Rehabilitation clinics can also profit from SRAclinic®, as in many patients released from the acute care atrial fibrillation has not been diagnosed despite suspicion.

 

How does SRAclinic® work?

The success of SRAclinic® is based on the use of the maximal available recording time of the patient's ECG. On the other hand there is that unique algorithm which fully automatically detects fibrillation episodes in a quality as performed by a cardiologist. This results in that detection rate of fibrillation episodes never reached before. Beyond that, the algorithm scans the ECG for possible deviations from normal sinus rhythm which might be a hint to previously occurred fibrillation episodes. These patients should be monitored for atrial fibrillation even after the acute care period which can be easily done with SRA24®.

Process of a SRAclinic® examination


1a Monitor automatically surveys the ECG
1b Traditional ECG conduction via separate electrodes
2 Safe and anonymous data transfer via the internet
3 Automatic analysis on the server of apoplex medical technologies – the data of the original ECG will remain stored on the SRA® server and can be accessed through the SRAviewer®
4 Prompt delivery of the analysis report via e-mail or internet access within a few minutes. Access to the SRAviewer with print out function.
