Ongoing Research Projects (at the time of 2019, update follows)

Clinical sepsis research | SepsisDialog

Our research is focussed on the new sepsis definition, medication during the acute phase of severe sepsis and septic show and on computer assisted sepsis diagnostics.

Sreening for Leiomyosarcoma | DKSM

About 50% of all leiomyosarcoma were treated according to the leiomyoma treatment protocol, because malignancy was not suspected at the time of surgery. We are working on a screening system to reduce the number of inadequate surgery using data from the DKSM (German Clinical Center of Excellence for Genital Sarcomas and Mixed Tumors) and outpatient study center.

Cardiovascular diseases | DZHK

We are currently screening and evaluating data of the orthostatic test from the cross-sectional study SHiP (Study of Health in Pomerania). In particular we are looking for clinical marker of the coronary artery disease.

Smell Capacity Disorders

In cooperation with Dr. Beule (ENT) we are working on the prevalence and aetiology of smell capacity disorders. We use data from the SHiP study.

Endoscopic Third Ventriculostomy

In cooperation with Dr. Marx (Neurosurgery) we are working on a score system for predicting the success of the ETV which incorporates liquor data.

Heart Rate Variability and Annotation/Segmentation of the ECG

  • Robust Detection of Heart Beats in Multimodal Data: the PhysioNet/Computing in Cardiology Challenge 2014 (see challenge); UPDATE: 1st place in Phase I, Phase II: 2nd, Phase III: 5th. Abstract, QRS Detection (Comic).
  • Measures of Heart Rate Variability / Use of relative RR Intervals (see MarcusVollmer.github.io/HRV)
  • AF Classification from a short single lead ECG recording: the PhysioNet/Computing in Cardiology Challenge 2017 (see challenge);
  • ECG Working Group
