Quizplus · Accepted Answer

Tachycardia (fast heart rate) and depressed ST segment are the two most common ECG findings in patients with pulmonary embolism. Other possible ECG findings in this condition may include inverted T waves, right ventricular strain pattern, and atrial fibrillation. However, the combination of tachycardia and ST segment depression is the most sensitive and specific ECG pattern suggestive of pulmonary embolism.
