Background:In diabetic ketoacidosis (DKA), cardiac complications such as QTc interval prolongation can pose a risk for ventricular tachycardia. Circulation, Volume 150, Issue Suppl_1 , Page A4143624-A4143624, November 12, 2024. Inclusion criteria encompassed patients under 21 years with two 12-lead ECGs taken during and after DKA resolution.

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. McLaren : We’ve answered the first question – Sinus Tachycardia with episodic runs of wide QRS (RBBB morphology) and PVC’s.

His prehospital ECG showed "inferior" ST depression and high voltage, with tachycardia. I suspected no OMI, that this could be due to LVH plus tachycardia. Conclusion: Type II MI probable due to hypoxia and tachycardia from resp arrest and amphetamine use. On arrival to the ED, the patient was diaphoretic, tachycardic.

But there are 3 other wide beats in the tachycardia that begins with beat #6 ( = beats #7; 13,14 ). Most Torsades is the result of a pause-dependent effect that predisposes to development of the malignant arrhythmia ( Dohadwala et al — Heart Rhythm Case Rep 3(2):115-119, 2017 ).

The ECG shows sinus tachycardia, a narrow, low voltage QRS with alternating amplitudes, no peaked T waves, no QT prolongation, and some minimal ST elevation in II, III, and aVF (without significant reciprocal STD or T wave inversion in aVL). It is difficult to tell if there is collapse during diastole due to the patient’s tachycardia.

POTS stands for postural orthostatic tachycardia syndrome. Let’s call it Postural Orthostatic Tachycardia Syndrome – that’s not really a diagnosis – it’s just a medical jargon filled term for what the patient has just told us. What is POTS? When you examine them, the heart rate can be found to be excessively fast.

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?
