Transvenous pacing therapy is a life-saving technique for patients with clinically significant bradyarrhythmias. For most symptomatic bradyarrhythmias in small animals, there is no effective substitute for cardiac pacing. The methods employed for pacemaker placement, although potentially time-consuming, are not technically difficult. This article discusses the indications, techniques, clinical decision-making, and potential complications associated with temporary and permanent transvenous cardiac pacing.

Background: Traumatic physical injuries can lead to psychological distress and increased risk of psychiatric disorders, often reflected in dysregulated autonomic responses measurable through heart rate variability (HRV). Slow-paced breathing has shown potential in enhancing HRV, but its effectiveness in injured survivors remains unexplored. This study investigates the effect of slow-paced breathing on HRV among injured survivors compared to non-injured individuals and explores the influence of psychological distress and spontaneous respiratory rate on this effect.

Objective: To describe the outcome of a case of severe drug-resistant fetal tachyarrhythmia with progressive hydrops treated with fetoscopic transesophageal pacing (FTEP).
Method: A case of fetal tachyarrhythmia complicated by progressive hydrops is presented. The fetus, diagnosed at 26 weeks of gestation, had supraventricular tachycardia with a mechanism suggestive of atrial reentry.

Resonance frequency (RF) is characterized as the specific frequency at which a system, equipped with delayed self-correction or negative feedback mechanisms, exhibits maximal amplitude oscillations in response to an external stimulus of a particular frequency. Emerging evidence suggests that the cardiovascular system has an inherent RF, and that breathing at this frequency can markedly enhance health and cardiovascular function. However, the efficacy of resonance frequency breathing (RFB) and the specific responses of the cardiovascular, respiratory, and central nervous systems during RFB remain unclear.
