Refractory Premature Ventricular Complex Triggered Ventricular Fibrillation Responsive to Cardiac Sympathetic Denervation

open access: yesAnnals of Internal Medicine: Clinical Cases, 2022
A healthy 34-year-old woman sustained refractory idiopathic ventricular fibrillation (IVF) secondary to premature ventricular contractions (PVCs). Ischemic, structural, and genetic evaluations did not identify an attributable pathology. Here, we review the epidemiology, prognosis, and management of PVC-induced IVF. We additionally highlight the utility

Cardiac troponins in intensive care [PDF]

open access: yes, 2005
The cardiac troponins are integral components of the myofibrillary apparatus and they regulate muscle contraction. The measurement of cardiac troponins has replaced other biomarkers for the specific detection of myocardial necrosis and for the diagnosis ...

Effects of spironolactone on extrasystoles and heart rate variability in haemodialysis patients: a randomised crossover trial

open access: yesUpsala Journal of Medical Sciences, 2021
Background: Spironolactone treatment reduces mortality in haemodialysis (HD) patients. The objective of this study was to evaluate if spironolactone affects cardiac electric activity in this population. Methods: Participants were randomised to start with

Ventricular tachycardia from intracardiac hematoma in the setting of blunt thoracic trauma

open access: yesIndian Heart Journal, 2014
In the victims of motor vehicle accidents, unrecognized myocardial injuries may pose diagnostic and therapeutic challenges. Herein, we present a case of a 17-year-old man who developed multiple ventricular premature complexes and nonsustained ventricular

Reactivation of the mitosis-promoting factor in postmitotic cardiomyocytes [PDF]

open access: yes, 2003
Cardiomyocytes cease to divide shortly after birth and an irreversible cell cycle arrest is evident accompanied by the downregulation of cyclin-dependent kinase activities.

Mena/VASP and αII-Spectrin complexes regulate cytoplasmic actin networks in cardiomyocytes and protect from conduction abnormalities and dilated cardiomyopathy [PDF]

open access: yes, 2013
BACKGROUND: In the heart, cytoplasmic actin networks are thought to have important roles in mechanical support, myofibrillogenesis, and ion channel function.

Intramuscular Diphenhydramine Does Not Affect Acute Doxorubicin Infusion-Related Arrhythmia Number or Severity in a Prospective Crossover Study in Canine Lymphoma: A Pilot Study

open access: yesFrontiers in Veterinary Science, 2020
Background: Doxorubicin (DOX) is one of the most effective chemotherapeutics for canine high-grade lymphoma. In addition to dose-dependent chronic cardiotoxicity, DOX can trigger acute cardiac arrhythmias during drug infusion.

Sports Activity and Arrhythmic Risk in Cardiomyopathies and Channelopathies: A Critical Review of European Guidelines on Sports Cardiology in Patients with Cardiovascular Diseases

open access: yesMedicina, 2021
The prediction and prevention of sudden cardiac death is the philosopher’s stone of clinical cardiac electrophysiology. Sports can act as triggers of fatal arrhythmias and therefore it is essential to promptly frame the athlete at risk and to carefully ...
