The Daniel score was found to correspond to the degree of perfusion defect on ventilation-perfusion lung scanning, and a score > 8 predicted worsened clinical outcomes, including death, shock, or respiratory failure. 9 in 2001 that assigns points (0 to 21) to ECG components that predicted increased pulmonary arterial pressure (Figure 1). A scoring system was developed by Daniel et al. 3, 7, 8 The 12-lead electrocardiogram (ECG) also provides information about severity of PE. 4- 6 Well-recognized methods for risk stratification include scoring systems, blood biomarkers (troponins I and T, brain natriuretic peptides), echocardiographic findings of RV strain, and findings of a dilated RV on computed tomography (CT) scanning. 1- 3 Patients with low-risk PE might be considered for immediate treatment at home. 1, 2 Experts generally agree that patients with PE and right ventricular (RV) failure have an elevated risk of hemodynamic collapse and should be considered for additional treatment beyond standard anticoagulation, including fibrinolytic therapy. Treatment guidelines recommend that clinicians employ a clinical strategy that includes the risk stratification of patients with pulmonary embolism (PE) to estimate the probability of circulatory shock and 30-day all-cause mortality. This systematic review and meta-analysis revealed 10 studies, including 3,007 patients with acute PE, that demonstrate that six findings of RV strain on 12-lead ECG (heart rate > 100 beats/min, S1Q3T3, complete RBBB, inverted T waves in V1–V4, ST elevation in aVR, and atrial fibrillation) are associated with increased risk of circulatory shock and death. Patients who were outcome-negative had a significantly lower mean ± SD Daniel score (2.6 ± 1.5) than patients with hemodynamic collapse (5.9 ± 3.9 p = 0.039, ANOVA with Dunnett's post hoc), but not patients with all-cause 30-day mortality (4.9 ± 3.3 p = 0.12). OR data showed no evidence of publication bias, but the proportions of patients with hemodynamic collapse or death and S1Q3T3 and RBBB tended to be higher in smaller studies. The authors also assessed heterogeneity (I 2) and calculated the odds ratios (OR) for each ECG sign from the random effects model if I 2 > 24% and fixed effects if I 2 100 beats/min, S1Q3T3, complete RBBB, inverted T waves in V1–V4, ST elevation in aVR, and atrial fibrillation) had likelihood and ORs with lower-limit 95% confidence intervals above unity, suggesting them to be significant predictors of hemodynamic collapse and 30-day mortality. Papers were assessed for selection and publication bias. Papers with evidence of a predefined reference standard for PE and the results of 12-lead ECG, stratified by outcome (hemodynamic collapse, defined as circulatory shock requiring vasopressors or mechanical ventilation, or in hospital or death within 30 days) were included. Case reports, non-English papers, and those that lacked either patient outcomes or ECG findings were excluded. Studies were identified by a structured search of MEDLINE, PubMed, EMBASE, the Cochrane library, Google Scholar, Scopus, and bibliographies in October 2014.

The objective of this study was to measure the prognostic value of specific ECG findings (the Daniel score, which includes heart rate > 100 beats/min, presence of the S1Q3T3 pattern, incomplete and complete right bundle branch block, and T-wave inversion in leads V1–V4, plus ST elevation in lead aVR and atrial fibrillation suggestive of RV strain from acute pulmonary hypertension), in patients with acute PE.

The hypothesis was that 12-lead electrocardiography (ECG) can aid in this determination. Treatment guidelines for acute pulmonary embolism (PE) recommend risk stratifying patients to assess PE severity, as those at higher risk should be considered for therapy in addition to standard anticoagulation to prevent right ventricular (RV) failure, which can cause hemodynamic collapse.
