Prohormones in the early diagnosis of cardiac syncope [PDF]

open access: yes, 2017
Background--The early detection of cardiac syncope is challenging. We aimed to evaluate the diagnostic value of 4 novel prohormones, quantifying different neurohumoral pathways, possibly involved in the pathophysiological features of cardiac syncope ...

The carotid body as a putative therapeutic target for the treatment of neurogenic hypertension [PDF]

open access: yes, 2013
In the spontaneously hypertensive (SH) rat, hyperoxic inactivation of the carotid body (CB) produces a rapid and pronounced fall in both arterial pressure and renal sympathetic nerve activity (RSA).

Asymptomatic Sinus Bradycardia Post-Bariatric Surgery: A Case Report

open access: yesProceedings of Singapore Healthcare, 2022
Bradyarrhythmia as a result of significant weight loss post-bariatric surgery is slowly gaining recognition in few case reports and even fewer studies. However, awareness of its diagnosis and management amongst physicians remains modest. We report a case

Symptomatic Long Pauses and Bradycardia due to Massive Multinodular Goiter

open access: yesCase Reports in Cardiology, 2017
Sinus node dysfunction with symptomatic bradycardia or chronotropic incompetence is generally an indication for pacemaker implantation. However, in patients with symptomatic sinus bradycardia, the identification and treatment of underlying pathologies ...

Recanalization of the Chronically Occluded Internal Carotid Artery: Review of the Literature. [PDF]

open access: yes, 2020
Introduction: We reviewed the literature on interventions for patients with medically refractory chronically occluded internal carotid artery (COICA) to assess the risks and/or benefits after recanalization via an endovascular technique (ET) or hybrid ...

The effects of repetitive electric cardiac stimulation in dogs with normal hearts, complete heart block and experimental cardiac arrest [PDF]

open access: yes, 1955
Direct cardiac stimulation was conducted in the open chest. In normal animals, auricular stimulation at frequencies faster than the spontaneous rate caused little change in vascular pressures or cardiac output.

Electrocardiography in horses, part 2: how to read the equine ECG [PDF]

open access: yes, 2010
The equine practitioner is faced with a wide variety of dysrhythmias, of which some are physiological. The recording of an exercise electrocardiogram (ECG) can help distinguish between physiological and pathological dysrhythmias, underlining the ...

A critical reappraisal of the carotid sinus and carotid bulb: Distinguishing neurohistological function from vascular geometry

open access: yesThe Anatomical Record, EarlyView.
This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...
