A patient in the ICU with significant underlying cardiac disease [HFrEF 30%, non-ischemic cardiomyopathy, LBBB s/p CRT-D (biventricular pacer), AVNRT s/p ablation a few yrs ago, hx sinus tachycardia while on max tolerated BB therapy] went into a regular wide-complex tachycardia after intubation for severe COPD exacerbation.

An Initial ECG was performed: Initial ECG: Sinus tachycardia with prolonged QT interval (QTc of 534 ms by Bazett). She was admitted to the ICU where subsequent ECGs were performed: ECG at 12 hours QTc prolongation, resolution of T wave alternans ECG at 24 hours Sinus tachycardia with normalized QTc interval.

A 65 y/o Female was admitted to the ICU for septic shock. From afar, there is gross tachycardia, cadence irregularities, and narrow QRS complexes that may, or may not, be Sinus in origin; and finally – a cacophony of wide complexes that might very well be ventricular in origin. Question 2: What explains the conduction abnormalities?

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;

There is a regular, wide complex, (mostly) monomorphic tachycardia. The differential of wide, regular, monomorphic tachycardia is: VT or SVT with aberrancy, all +/- hyperkalemia (see diagrams below). He made it to the ICU, however the patient unfortunately expired approximately 24 hours after ICU admission.

She had a single chamber ICD/Pacemaker implanted several years prior due to ventricular tachycardia. Answer : The ECG above shows a regular wide complex tachycardia. Said differently, the ECG shows a rather slow ventricular tachycardia with a 2:1 VA conduction. Cardiac output (CO) was being maintained by the tachycardia.

The findings include sinus tachycardia, characteristic QRS morphology most diagnostic in V3 with a small R wave followed by a very large S wave with a convex upward ST segment morphology, ST segment strain morphology in the inferior and anterior leads leading to deep symmetric T-wave inversion. and tachycardia, 1.8. incomplete RBBB 1.7
