Myxomatous mitral valve disease, an acquired valvular degeneration, is the most common cardiac disorder in dogs, affecting approximately 10% of dogs in primary care veterinary practice. Dogs with myxomatous mitral valve disease frequently require anaesthesia for routine procedures.

ABSTRACT Introduction Multipoint pacing (MPP) delivers sequential stimuli from multiple left‐ventricular electrodes, potentially improving cardiac resynchronization therapy (CRT) response versus conventional biventricular pacing (BiV). We performed an updated systematic review and meta‐analysis to synthesize contemporary evidence.

Acute intermittent hypercapnic hypoxia augments left ventricular contractility
Abstract figure legend Twenty‐four healthy adults were studied to determine the effects of an acute session of 40 min of intermittent hypercapnic hypoxia on cardiac performance. Cardiac function was assessed via echocardiography at rest and during graded stages of lower‐body negative pressure before and after the intervention to quantify load ...

Repolarization adaptation to rapid change in heart rate in human models – a review
Abstract figure legend This review focuses on non‐invasive assessment of repolarization duration and dispersion (heterogeneity) adaptation to change in heart rate (HR). HR was increased incrementally by left atrial pacing during an electrophysiology (EP) study and by a bolus injection of atropine and in a step up/down fashion by repeated right atrial ...

Abstract figure legend The β1‐adrenergic receptor is the predominant adrenergic subtype expressed on cardiac myocytes. Upon stimulation it activates downstream signalling pathways that increase the heart rate and cardiac output to meet metabolic demands.
