Feasibility of CardioSecur®, a Mobile 4-Electrode/22-Lead ECG Device, in the Prehospital Emergency Setting

Abstract

Background: This study explores the application of CardioSecur ® (CS-ECG), a hand-held 4-electrode/22-lead ECG-device, in comparison with conventional 12-lead electrocardiogram (c12L-ECG) in patients with acute chest pain in the prehospital emergency setting. Methods: CS-ECG systems were provided for two physician-staffed emergency ambulances and parallel recordings of c12L-ECG and CS-ECG were obtained from all patients with acute chest pain. Treating emergency physicians were asked to evaluate the CS-ECG system with a standardized questionnaire. Following study completion, acquired ECGs were analyzed separately by two independent cardiologists blinded to all other medical records. Results: Over a period of 20 months a total of 203 patients were included in our study. According to a standardized questionnaire, 79% of emergency medical professionals preferred application of CS-ECG, with 87% of teams judging CS-ECG to be beneficial for patients. Morover, 79% of physicians reported a reduction in time to definitive diagnosis with implementation of CS-ECG. The majority of professional users attested user-friendliness and feasibility of CS-ECG in terms of easy general handling (94%), application (93%), and placement of electrodes (98%). During prehospital triage, both c12L-ECG and CS-ECG correctly identified 31 (91%) patients with ST-elevation myocardial infarction (STEMI). Conclusion: In this first pilot study, implementation of the CardioSecur ®-ECG system in the prehospital emergency setting demonstrated feasibility and user-friendliness so that emergency teams generally preferred CS-ECG to c12L-ECG. Diagnostic yield of CS-ECG was similar to c12L-ECG recordings.

Physician preferences associated with powered intraosseous access systems: Safety features, reliability, and ease of use

“…Assessment of physician preferences is an essential step in implementing novel medical devices. It has been demonstrated that the adoption of new technologies by clinicians is influenced by the perceived benefit to the patient and how easy it is to use the device 12 . This study shows that ease of use is a major factor in physician preferences regarding powered IO systems.…”

This is consistent with the findings from previous studies evaluating preferences for IO system features, 13 , 14 which suggest that clinicians prefer features that enhance ease of use.…”

Wearable-basierte Detektion von Arrhythmien

“…22-Kanal-EKG zu generieren. Der Nutzen dieser vereinfachten EKG-Ableitung im klinischen Einsatz konnte kürzlich gezeigt werden[59]. Andere Systeme nutzen beispielsweise adhäsive Patches, Brustbänder, Armbänder oder auch Hemden mit integrierten Elektroden[9,17,19,28,43].Weiter verbreitet sind die Hand-oder Daumen-EKGs.…”

Temporal trends in the pre-procedural TIMI flow grade among patients with ST- segment elevation myocardial infarction – From the ACSIS registry

“…These time delays reported are significantly shorter than in our real-world cohort and thus the effect of pre-hospital ticagrelor could have been blunted in this study [8] . The increasing availability and use of ECG-mobile devices may also be help tool in the early identification and thus improved outcomes of STEMI patients [9] . Further studies are needed to validate this.…”
