Background: Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a rare inherited arrhythmia disorder characterized by ventricular arrhythmia triggered by adrenergic stimulation.

Case Presentation: A 9-year-old boy presented with convulsions following physical exertion. Bidirectional ventricular tachycardia (VT) during a treadmill test led to the diagnosis of catecholaminergic polymorphic ventricular tachycardia (CPVT).

Right ventricular reserve in cardiopulmonary disease: a simultaneous hemodynamic and three-dimensional echocardiographic study.

J Heart Lung Transplant

December 2024

Department of Cardiology, Ospedale San Luca IRCCS Istituto Auxologico Italiano, Milano, Italy; Department of Management, Information and Production Engineering, University of Bergamo, Dalmine (BG), Italy.

Background: RV reserve has been linked to exercise capacity and prognosis in cardiopulmonary diseases. However, evidence in this setting is limited, due to the complex shape and load dependency of the RV. We sought to study right ventricular (RV) adaptation to exercise by simultaneous three-dimensional echocardiography (3DE) and right heart catheterization (RHC).

Background: Recent studies provide strong evidence for a key role of skeletal muscle pathophysiology in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). In a 2021 review article on the pathophysiology of ME/CFS, we postulated that hypoperfusion and ischemia can result in excessive sodium and calcium overload in skeletal muscles of ME/CFS patients to cause mitochondrial damage. Since then, experimental evidence has been provided that supports this concept.

Background: The last phases of a competitive game are when shoulder injuries most commonly happen, and fatigue is thought to be a major contributing factor, perhaps because of reduced proprioception and motor control. The purpose of this study was to investigate the effect of concentric fatigue on proprioception, motor control, and performance of the upper limb in handball players.

Methods: Forty-six right-handed handball players (all males, age 26.

Evidence of Left Ventricular Cardiac Remodeling After 6 Weeks of Sprint Interval Training.

Scand J Med Sci Sports

December 2024

Division of Clinical Physiology, Department of Laboratory Medicine, Karolinska Institutet, Stockholm, Sweden.

Sprint interval training (SIT) leads to similar improvements in maximal oxygen uptake (V̇O) and maximal cardiac output as previously reported for traditional endurance training, but the exercise-induced effects on cardiac remodeling are still largely unknown. The aim of the current study was therefore to explore the effects of SIT on cardiac structure and function assessed by echocardiography in relation to, and controlling for, changes in both blood volume (BV) and heart rate (HR). Healthy men and women (n = 28) performed 6 weeks of SIT.
