“…Automated ECG interpretation algorithms have been suggested as a safe and effective method for diagnosing STEMI [40]. However, the automated algorithms do not detect the STEMI equivalent changes, the error rate is high and sensitivity is generally low [41,42]. In a recent study, Garvey and colleagues investigated three automated algorithms and found sensitivities of approximately 60% and the algorithms suggested false positive STEMI diagnoses in 10% of patients without STEMI.…”

Primary percutaneous intervention (PPCI) is the preferred treatment in patients with ST elevation myocardial infarction (STEMI) if this can be performed in a timely manner. The 2012 ESC Guidelines on management of AMI in patients presenting with ST-segment elevation advice that PPCI should be performed within 120 min of first medical contact. Prehospital diagnosis of patients with STEMI is performed to save time and make PPCI available to the majority of patients. Although diagnosing patients with STEMI is usually easy, there are important pitfalls and patients with STEMI are missed on occasion. In addition, it is well know that patients without ST elevation may also have a high-risk cardiac condition. The 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without persistent ST-segment elevation stress the importance of urgent CAG in patients with high-risk non ST-segment elevation myocardial infarction (NSTEMI). Unfortunately, these patients are difficult to diagnose in the acute phase and important time may be spend establishing the correct diagnosis. Prehospital biomarker measurement has emerged as a method to gain important additional information. We review the evidence on prehospital diagnosis of patients with STEMI and, In addition, we present the current knowledge on the new diagnostic methods that could have a future role in prehospital rule-in and rule-out of cardiac disease.

“…A standard 12-lead ECG was recorded after the CGM. The principles of the CGM have been published in detail elsewhere (6)(7)(8). Briefly, four electrodes were placed perpendicular at four points on the patients thorax: point 1, at point V4 of Wilson, in the 5th intercostal space on mid clavicular line; point 2, at a point opposite to electrode 1 on back (at point V8 of Wilson); point 3 located perpendicularly above electrode 1 at 0.…”

“…However, exercise ECGs are often not meaningful due to limited stress capacity of the patient or are even contraindicated (4). CGM is a novel electrodiagnostic method that analyzes three-dimensional information on cardiac potentials (5,6). Additionally, CGM provides quantitative computer analysis of this three-dimensional information.…”

Background: Cardiogoniometry (CGM) is a novel spatiotemporal electrocardiographic method utilizing computer-assisted threedimensional data on cardiac potentials. Objectives: This study compares the accuracy of CGM and electrocardiography (ECG) by detecting coronary artery disease (CAD) with reference to angiography as a well-known gold standard. Patients and Methods: A total of 390 patients undergoing coronary angiography with CAD were enrolled. CGM was performed a few hours prior to coronary angiography. A standard 12-lead ECG was recorded after the CGM. The CGM and ECG results were recorded and analyzed by an independent investigator blinded to all patient data and the results of the coronary angiography. Results:The coronary angiography showed a normal coronary artery in 263 patients (67.4%). A median of CGM score was 1 (0-2), the minimum score was 0 and maximum score was 8. A total of 90 patients (31%) showed predefined ST-segment/T-wave changes in the resting 12-lead ECG. CGM yielded a sensitivity of 84% and specificity of 81% and the ECG yielded a sensitivity of 29% and specificity of 67% when compared with the coronary angiography. Conclusions: CGM is a non-invasive technique recently developed for quantitative three-dimensional vectorial analysis of myocardial activity and detection of ischemia and infarction. This technique is clearly more sensitive and more specific than a standard resting 12-lead ECG.
