Background: Thoracic aortic dissection (TAD) is an uncommon complication in patients with Tetralogy of Fallot (TOF). Information concerning risk factors for TAD in patients with TOF is very limited.

Methods: We report a case of Stanford type A TAD in a female patient with previously repaired TOF.

Article Synopsis
  • Pulmonary vein isolation (PVI) effectively manages paroxysmal atrial fibrillation (PAF), and this study investigates how P wave parameters from ECG can predict PVI success.
  • The research involved 211 patients undergoing first-time PVI, measuring various P wave metrics before the procedure, and found that specific parameters correlated with successful outcomes at 12 months.
  • Key predictors of PVI failure included increased corrected P wave duration (PWDc), decreased P wave amplitude (PWV) and area (PWA), and intra-atrial block (IAB), while P wave dispersion (PWDisp) and terminal force in V1 (PTFV1) didn’t show significant correlation.

Background: Prolonged exposure to hand-arm vibration is associated with a disorder of the vascular, neurological, and musculoskeletal systems of the upper limb known as hand-arm vibration syndrome (HAVS). Currently, the evidence of HAVS in tropical environments is limited.

Objectives: To determine the prevalence and severity of HAVS among tyre shop workers in Kelantan, Malaysia.

In this paper, a new method for clustering analysis of QRS complexes is proposed. We present an efficient Arrhythmia Clustering and Detection algorithm based on medical experiment and Ant Colony Optimization technique for QRS complex. The algorithm has been developed based on not only the general signal detection knowledge, but also on the ECG signal's specific features.
