Studies of ECG findings in Pulmonary Embolism: | |||
• Ferrari E, et al. The ECG in pulmonary embolism. Chest. 1997;111:537-43 | |||
− Anterior T wave inversions had a sensitivity of 85%, specificity of 81% for massive PE | |||
in 80 patients with suspected to have PE; this was the most common finding on ECG | |||
(68%), followed by S1Q3T3 (50%) | |||
• Rodger M, et al. Diagnostic value of the electrocardiogram in suspected pulmonary embolism. | |||
Am J Cardiol. 2000; 86:807-9 | |||
− In 246 consecutive patients with PE compared to controls, only tachycardia and | |||
incomplete RBBB differentiated PE from no PE. | |||
• Sreeram N, et al. Value of the 12-lead ECG at hospital admission in the diagnosis of PE. Am | |||
J Cardio 1999;73:298-303 | |||
− In 49 patients with PE, ECGs were analyzed for RV overload. Although many of the | |||
patients with PE had signs of RV overload on ECG, these signs were non-specific and | |||
performed poorly in patients with underlying lung disease | |||
• Stein PD, et al. Clinical characteristics of patients with acute pulmonary embolism. Am J Cardio. 1991;68:1723 | |||
− In this retrospective study of 117 patients with acute PE, non-specific ST-T wave changes were the most commonfinding on the ECG (49%) | |||
