Asynchronous development of electrical remodeling and cardiac hypertrophy in the complete AV block dog.
OBJECTIVE Left ventricular hypertrophy has been associated with the prolongation of QT-time, and an increased risk of ventricular arrhythmias. The renin angiotensin system has been implicated in the development of ventricular hypertrophy. At 5 weeks complete AV block (CAVB) in the dog, there is: (1) biventricular hypertrophy associated with a transient activation of components of the renin angi...
متن کاملSudden Cardiac Death Sudden Cardiac Death in the Athlete
Sudden cardiac death (SCD) in a young athlete commonly brings to the forefront the many gaps in knowledge regarding how to predict and prevent these rare tragic events.1–3 Although the number of athletic sudden deaths is relatively small, with 100 to 150 competitive deaths during sports in the United States annually, they represent an important and emotionally charged public health issue, perha...
متن کاملSudden death in a case of cardiac amyloidosis immediately after pacemaker implantation for complete atrioventricular block.
We report a patient with cardiac involvement associated with primary amyloidosis presenting marked left ventricular (LV) wall thickening, severely decreased systolic and diastolic function, and complete atrioventricular block (CAVB), who died suddenly of cardiac arrest caused by electro-mechanical uncoupling occurring immediately after permanent pacemaker implantation. Post mortem examination s...
متن کاملLeft ventricular cardiac myxoma and sudden death in a dog
BACKGROUND Myxoma is a very rare benign cardiac tumor in dogs. This is the first description of a cardiac myxoma originating from the left ventricular outflow tract, presumably causing sudden death. CASE PRESENTATION A previously healthy 12-year-old male West Highland white terrier was found dead during its 1-week stay in a kennel. The dog was known to have a cardiac murmur. On necropsy, a pe...
متن کاملEnhanced susceptibility for acquired torsade de pointes arrhythmias in the dog with chronic, complete AV block is related to cardiac hypertrophy and electrical remodeling.
BACKGROUND Chronic, complete AV block (CAVB) in the dog leads to ventricular hypertrophy, which has been described as an independent risk factor for arrhythmias. In this model, we examined (1) whether the short- and long-term electrical adaptations predispose to acquired torsade de pointes arrhythmias (TdP) and (2) the nature of the structural and functional adaptations involved. METHODS AND ...
