3-lead ECG may detect more serial changes than 12-lead in acute PE; hypothesis-generating and should not yet change practice.
Does a 3 orthogonal lead electrocardiogram with computer assisted interpretation improve the detection of serial electrocardiographic changes compared to a 12-lead electrocardiogram in patients with acute pulmonary embolism?
The 3 orthogonal lead electrocardiogram with computer-assisted interpretation is more helpful than the conventional 12-lead ECG for following serial electrocardiographic changes in patients with acute pulmonary embolism.
Dunn et al. (1976) studied this question.
