Retrospectively — I interpret this 1:1 retrograde conduction as diagnostic of a reentry SVT rhythm as the etiology of the initial tachycardia. As noted by Moodie in his manuscript on Adult Congenital Heart Disease ( Tex Heart Inst J: 38(6):705, 2011 ) — there are now more people over the age of 20 with CHD than under that age!

She was awake, alert, well perfused, with normal mental status and overall unremarkable physical exam except for a regular tachycardia, possible rales at both bases, some mild RUQ abdominal tenderness. Thus, I believe it is a regular, monomorphic, wide complex tachycardia. Or it could simply still be classic VT. What is the Diagnosis?

IMPRESSION: Given the presence of a wide tachycardia — with 2 distinct QRS morphologies, and no sign of P waves — a presumed diagnosis of B i D irectional Ventricular Tachycardia has to be made. Multifocal vs Polymorphic VT — September 23, 2011 post from Dr. S.

Here is his 12-lead ECG: The computer reads supraventricular tachycardia. In these cases, they were misdiagnosed as sinus tachycardia (not PSVT): Notice there is a "P-wave" just before the QRS in V1 Notice there is a "P-wave" directly superimposed (on top of) the T-wave in V1. Narrow complex tachycardia at rate of 135.

Chagas disease (ChD) was associated with increased rates of ventricular tachycardia and ventricular fibrillation in ICD patients only in the initial two periods, but there was no statistical difference in the last period. Time periods were chosen based on the establishment of the Arrhythmia Service in 2011.

Answer : you must treat the patient's underlying condition causing sinus tachycardia, and repeat the ECG at the lower heart rate.

During observation in the ED the patient had multiple self-terminating runs of Non-Sustained monomorphic Ventricular Tachycardia (NSVT). This patient very likely has some form of idiopathic ventricular tachycardia. Of the ventricular outflow tract tachycardias (RVOT-VT) makes up 80-90%.
