To the Editor:—
In connection with the editorial in the Jan. 26, 1952, issue of The Journal, page 289, on the differential diagnosis between pulmonary embolism and myocardial infarction, I should like to refer you to a paper on the electrocardiographic changes in pulmonary embolism in the April, 1952, issue of the Florida Medical Journal (38:701-712)The electrocardiographic differentiation between the two, particularly that between infarction of the posterior wall and pulmonary embolism, can often be greatly facilitated by attention to the ST and T wave changes in the precordial V leads over the right side of the heart. In posterior wall infarction they are reciprocally elevated and increased in amplitude, never inverted; in pulmonary embolism they may either remain unchanged or show inversion, i. e., the right ventricular "strain pattern" of acute cor pulmonale.
