CASE CONTINUED She was admitted to the ICU. Even with tachycardia and a paced QRS duration of ~0.16 Smith has provided excellent overview of measuring and correcting QT interval in scenarios where QRS duration is prolonged (e.g., LBBB, ventricular pacing, etc.)." J Am Coll Cardiol.

The patient was upgraded to the ICU for closer monitoring. and tachycardia, 1.8. Finally , they found that S1Q3T3, precordial T-wave inversions V1-V4, and tachycardia were independent predictors of PE. Echocardiogram showed severe RV dilation with McConnell’s sign and an elevated RVSP. inverted T-waves in V1 and V2, 1.8;
