Severe Hypertriglyceridemia Without Pancreatitis Causing Total Pseudohypocalcemia With True Ionized Symptomatic Hypocalcemia: A Diagnostic Pitfall

Clinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT Severe hypertriglyceridemia (HTG) can interfere with laboratory assays. HTG‐induced pancreatitis usually presents with hypocalcemia, but the effect of severe HTG, with no associated pancreatitis, on calcium levels is not well described. We present a 25‐year‐old male with severe HTG and diabetes who presented with generalized weakness, nausea ...

Are patients admitted to emergency departments with regular supraventricular tachycardia (SVT) treated appropriately? [PDF]

, 2013
Regular supraventricular tachycardia (SVT) is frequently encountered in clinical practice. Guidelines are available from the National Service Framework (NSF) for the treatment of patients attending emergency departments (ED) with SVT.

Stabilizing Extreme Few‐Shot ECG Classification via Self‐Supervised Contrastive Pretraining

Annals of Noninvasive Electrocardiology, Volume 31, Issue 3, May 2026.
Under extreme few‐shot ECG classification, supervised training frequently collapses to degenerate solutions. Self‐supervised pretraining stabilizes optimization, eliminates early collapse, and enables reproducible multi‐class rhythm classification with limited labeled data. ABSTRACT In clinical electrocardiogram (ECG) analysis, high‐quality annotations

What is the best approach to the evaluation of resting tachycardia for an adult? [PDF]

, 2007
The best evidence about the diagnostic evaluation of resting tachycardias in adults is currently outlined by practice guidelines. 1 Initial evaluation includes clinical history, physical examination, and 12-lead electrocardiogram (ECG).

Technical Feasibility of the RHYTHMIA Mapping System in Pediatric Patients Weighing Less Than 20Kg

Pacing and Clinical Electrophysiology, Volume 49, Issue 5, Page 523-530, May 2026.
ABSTRACT Background Catheter ablation in pediatric patients remains technically challenging. The RHYTHMIA high‐density mapping system is increasingly used in pediatric electrophysiology; however, procedural experience in patients weighing less than 20 kg is limited.

A Review of Vagus Nerve Stimulation for Disease: Comprehensive Theory and Evidence for Mechanisms of Action

Comprehensive Physiology, Volume 16, Issue 2, April 2026.
Vagus nerve stimulation (VNS) effects span central and peripheral organ systems through diverse mechanistic pathways. This comprehensive review provides a unified synthesis of these mechanisms across neurological, cardiovascular, immunological, metabolic, and gastrointestinal domains, filling a critical gap and serving as a foundational resource for ...

Characterization of health care utilization in patients receiving implantable cardioverter-defibrillator therapies: An analysis of the managed ventricular pacing trial. [PDF]

, 2017
BACKGROUND: Implantable cardioverter-defibrillators (ICDs) are effective in terminating lethal arrhythmias, but little is known about the degree of health care utilization (HCU) after ICD therapies.
