Article Synopsis
  • Inpatient monitoring is traditionally recommended when starting sotalol, but this study aimed to evaluate the safety of initiating it in an outpatient setting.
  • The study reviewed 880 patients who started sotalol, mostly for atrial fibrillation, and monitored their QTc intervals over time to assess for significant prolongation and other clinical events.
  • Findings indicated that outpatient initiation of sotalol is generally safe, with minimal serious adverse effects and a low rate of QTc prolongation, although ongoing monitoring and follow-up are essential.

Skeletal muscle microvascular blood flow (MBF) plays an important role in glucose disposal in muscle. Impairments in muscle MBF contribute to insulin resistance and prediabetes. Animal studies show that short-term (3 day) high-fat feeding blunts skeletal muscle MBF before impairing insulin-stimulated glucose disposal.

Article Synopsis
  • The study aimed to evaluate how factors like vector length, implant angle, and patient characteristics influence the accuracy of electrogram sensing in insertable cardiac monitors (ICMs).
  • It involved analyzing 1800 ECG tracings from 150 participants using different distances, angles, and postures, finding that longer vector lengths (75 mm) and oblique angles improved P- and R-wave amplitudes significantly.
  • The findings suggest that optimizing vector length and implant angle can enhance electrogram visibility, which is crucial for reducing false alerts in cardiac monitoring.

Importance: Randomised trials have shown that catheter ablation (CA) is superior to medical therapy for ventricular tachycardia (VT) largely in patients with ischaemic heart disease. Whether this translates to patients with all forms and stages of structural heart disease (SHD-e.g.

Article Synopsis
  • Most modern cardiac implantable electronic devices (CIEDs) can now undergo MRI scans, which requires both pre- and post-scan checks, leading to increased workload for cardiac services.
  • A study covering three years revealed 739 CIED checks related to MRI scans, showing a rise in the demand for these checks over time.
  • The projected annual cost for handling CIED checks is expected to reach AUD$161,695 in ten years, highlighting the need for better budgeting and staff management.
