Neuroscience in the heart: Recent advances in neurocardiac communication and its role in cardiac arrhythmias

The International Journal of Biochemistry & Cell Biology

Abstract

Autonomic nervous system dysregulation is involved in the pathophysiology of multiple cardiac arrhythmias, and therefore modulating sympathetic or parasympathetic input to the heart provides novel therapeutic options for arrhythmia management. Examples include decreasing intrinsic cardiac neuron communication, patterned vagal nerve stimulation, denervation, and blockade of post-ganglionic neurons. However, lessons from ventricular arrhythmias, where increased sympathetic activity and vagal rebound activity both amplify arrhythmia risk, stress the importance of understanding the regulatory mechanisms that modulate the balance and levels of sympathetic and parasympathetic activity. Of critical need is an increased understanding of plasticity mechanisms in the autonomic nervous system, to a level similar to what is known in the central nervous system, in order to develop safe and effective neuromodulatory therapies.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
