AI Article Synopsis

  • A 60-year-old man experienced a myocardial infarction affecting the inferior wall of his heart, along with intermittent preexcitation syndrome.
  • In his ECG results, the abnormal Q waves typically seen in inferior leads were difficult to detect due to the effects of the intermittent preexcitation.
  • The patient also exhibited paroxysmal (random and sudden) asymptomatic second-degree atrioventricular block, coupled with inconsistent atrioventricular conduction that was supported by an accessory pathway, sometimes leading to a 2:1 ratio of conduction.

Article Abstract

We describe a case of a 60 year-old man after inferior wall myocardial infarction with intermittent preexcitation syndrome. In ECG, the pathologic Q waves in the inferior leads were masked by the intermittent preexcitation. In this patient, paroxysmal asymptomatic second-degree atrioventicular block coexists with inconstant atrioventricular conduction maintained by the accessory pathway, periodically 2:1.

ECG challenge: Intermittent wide QRS complexes in heterotaxy syndrome.

J Electrocardiol

January 2025

Division of Pediatric Cardiology, Department of Pediatrics, Medical University Graz, Graz, Austria.

We report wide QRS complexes appearing in conjunction with prolonged R-R intervals in a 5- year old patient with situs ambiguous and mirror image dextrocardia, who had undergone ASD and VSD closure at of the age of one. We present differential diagnoses of intermittent spontaneous QRS widening and refer to ECG lead positioning in mirror image dextrocardia patients.

Article Synopsis
  • - Telecardiology effectively enables ECG screening for large groups, successfully evaluating non-competitive athletes (NCA) across Italy over a four-year study period.
  • - In a sample of 216,424 NCA, 88 individuals (4.1 per 10,000) were identified with Wolff-Parkinson-White (WPW) syndrome, primarily in the 10-15 year age group, with no significant sex differences noted.
  • - The study revealed that the most common accessory pathways for WPW syndrome were in the right antero-septal, mid-septal, and postero-septal areas, with 9% of those diagnosed exhibiting intermittent pre-excitation.

Spontaneous pre-excited supraventricular tachycardias in a Labrador Retriever.

J Vet Cardiol

August 2024

Clinica Veterinaria Malpensa, Viale Marconi, 27, 21017, Samarate, VA, Italy; College of Veterinary Medicine, Cornell University, 930 Campus Road, 14853, Ithaca, NY, USA.

A four-year-old Labrador Retriever was presented for intermittent tachycardia. The electrocardiogram showed sinus rhythm conducted with ventricular pre-excitation and short runs of orthodromic atrioventricular reciprocating tachycardia. Four months later, the rhythm degenerated into a symptomatic sustained tachycardia, suspected to be pre-excited atrial fibrillation, a potentially life-threatening rhythm in the presence of an accessory pathway with a short refractory period.

Agammaglobulinemia represents the most profound primary antibody deficiency, stemming from early cessation of B-cell development. Deficiency in folliculin-interacting protein 1 (FNIP1) is a novel inborn error of immunity characterized by a severe defect in B-cell development, agammaglobulinemia, variable neutropenia, and hypertrophic cardiomyopathy. FNIP1 plays a critical role in B-cell development and metabolic homeostasis, establishing a metabolic checkpoint that ensures pre-B cells possess sufficient metabolic capacity to undergo division while concurrently limiting lymphogenesis due to abnormal growth.
