AI Article Synopsis

  • The study examines surface electrocardiograms (ECGs) during episodes of wide QRS complex tachycardia, a type of irregular heartbeat characterized by a prolonged QRS duration.
  • Adenosine triphosphate (ATP) is injected to observe its effects and understand the underlying mechanism of the wide QRS tachycardia.
  • The goal is to identify the physiological processes that lead to the conduction abnormalities observed in this type of tachycardia.

Article Abstract

The surface electrocardiograms during a wide QRS complex tachycardia and during the injection of 10 mg of adenosine triphosphate. What is the mechanism of this wide QRS tachycardia?

Background: Cardiac resynchronization therapy (CRT) is an essential treatment for patients with symptomatic heart failure and ventricular conduction abnormalities. Low-ejection-fraction (EF) cardiomyopathy often involves a wide QRS complex displaying a left bundle branch block (LBBB) morphology and markedly delayed activation of the LV lateral wall. Following CRT, patients with heart failure and LBBB have better outcomes and quality-of-life improvements.

Article Synopsis
  • Differentiating between ventricular tachycardia (VT) and supraventricular wide tachycardia (SWCT) using 12-lead ECG is challenging and has traditionally depended on manual interpretation, which can be limited by the user's expertise.
  • Recent research has introduced automated algorithms that may offer improved accuracy over manual methods, but there has been little direct comparison between these two approaches.
  • A study by LoCoco et al. (2024) evaluated the effectiveness of traditional manual ECG differentiation methods against five automated algorithms, analyzing 213 ECGs to assess their diagnostic performance.

Background: Wide QRS complex tachycardia (WCT) differentiation into ventricular tachycardia (VT) and supraventricular wide complex tachycardia (SWCT) remains challenging despite numerous 12-lead electrocardiogram (ECG) criteria and algorithms. Automated solutions leveraging computerized ECG interpretation (CEI) measurements and engineered features offer practical ways to improve diagnostic accuracy. We propose automated algorithms based on (i) WCT QRS polarity direction (WCT Polarity Code [WCT-PC]) and (ii) QRS polarity shifts between WCT and baseline ECGs (QRS Polarity Shift [QRS-PS]).

Severe Hyperkalemia in a Child with Vomiting and Diarrhea.

Clin Pract Cases Emerg Med

November 2024

Sidra Medicine, Department of Emergency Medicine, Ar-Rayyan, Qatar.

Case Presentation: A 13-month-old child with past medical history of congenital adrenal insufficiency presented to the emergency department with vomiting and diarrhea. Initially the child was noticed to have bradycardia with normal blood pressure. An electrocardiogram (ECG) showed tall T waves, broad QRS complex, and widened PR interval suggestive of severe hyperkalemia.
