Mechanisms Of Atrial Arrhythmia: Investigations Of The Neuro-Myogenic Interface In The Mouse, Jari Michael Tuomi
Mechanisms Of Atrial Arrhythmia: Investigations Of The Neuro-Myogenic Interface In The Mouse, Jari Michael Tuomi
Electronic Thesis and Dissertation Repository
Arrhythmia mechanisms rely on multiple factors including structural (myogenic), nervous (neurogenic), and interrelated (the neuro-myogenic interface) factors. I hypothesized that due to this neuro-myogenic interface, the intrinsic cardiac autonomic nervous system (ICANS) is involved in most atrial arrhythmias. This thesis also provides a "Threshold Model" as a tool to assess the role of different physiological factors influencing arrhythmia. This model allows relative comparison and interpretation of the role of various factors influencing arrhythmogenesis. The mouse allows relatively simple manipulation of genes to determine their role in arrhythmia. This thesis determined what atrial arrhythmias are inducible in the mouse (in vivo) …
