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.

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

Prior ECG on file: Sinus tachycardia, imperfect baseline, otherwise unremarkable. Sinus tachycardia with unequivocal evidence of hyperkalemia, including widened QRS with "pulled apart" morphology (widened QRS) compared to baseline, as well as clearly peaked T-waves. Compartment pressures in the right calf were all 40-50 mmHg.

On arrival in the ED, he was hypotensive with a systolic blood pressure in the 70s. After initiating treatment for hyperkalemia, repeat ECG showed resolution of Brugada pattern: The ECG shows sinus tachycardia. A Very Wide Complex Tachycardia. Fluid resuscitation was initiated.
