Electrocardiographic Findings in a Young Man With Tachycardia and Hypotension

Electrocardiographic Findings in a Young Man With Tachycardia and Hypotension A 25-year-old man presented to the emergency department complaining of shortness of breath, cough, and malaise, which had progressed over the preceding several weeks. He had a 7-year history of daily methamphetamine use. He had presented to the emergency department 3 times in the previous month complaining of similar symptoms and had been discharged with treatment for an upper respiratory infection; there was no evidence of hemodynamic instability. At this presentation, however, his blood pressure was 95/60 mm Hg, his heart rate was 114 beats/min, and his oxygen saturation was 98% on room air. Physical examination revealed a jugular venous pressure of 15 cm H2O, bilateral pulmonary rales, an inferolaterally displaced point of maximal impulse, and an S3 gallop, all of which were new findings compared with those of previous examinations. A chest x-ray film revealed bibasilar pulmonary infiltrates, consistent with pulmonary edema, and an enlarged cardiac silhouette. An electrocardiogram (ECG) was obtained (Figure 1).
