The sympathetic nervous system (SNS) is essential for the body's immediate response to stress, initiating physiological changes that can be measured through sympathetic nerve activity (SNA). While microneurography (MNG) is the gold standard for direct SNA measurement, its invasive nature limits its practical use in clinical settings. This study investigates the use of multi-wavelength photoplethysmography (PPG) as a non-invasive alternative for SNA measurement.

Introduction: Quetiapine shares sodium channel-blocking properties with tricyclic antidepressants. We present the electrographic findings in two patients with severe quetiapine poisoning.
Case Summaries: Two patients poisoned with quetiapine presented with impaired consciousness, requiring mechanical ventilation and vasopressor support, with one also experiencing status epilepticus.

The giant anteater (Myrmecophaga tridactyla) is a vulnerable species that is threatened mostly due to anthropogenic pressure. The anteater is a highly specialized insectivore, challenging the species' ex situ maintenance and conservation efforts. Several dietary-associated health issues have been reported in captive anteaters, including heart conditions such as dilated cardiomyopathy.

Background: The interrupted technique of left bundle branch pacing (LBBP) limits the continuous monitoring of paced electrocardiogram and intracardiac electrogram (EGM) transitions, which may result in overlooked or misinterpreted subtle transitions.
Objectives: This study aimed to explore the electrophysiological characteristics of lead position-dependent EGM continuous transitions to evaluate lead depth and to investigate the clinical significance of transseptal pacing modalities.
Methods: A continuous pacing and recording technique enabled by a rotatable connector was used to allow the real-time monitoring of progressive changes in paced EGM and electrocardiographic morphology.
