Advances in transcriptional regulation of the heart rhythm.

Underlying normal cardiac rhythm is a network of transcriptional programs that ensures normal impulse initiation and impulse propagation. We highlight work that shows how alterations in individual transcriptional networks can lead to increased arrhythmia susceptibility, cardiomyopathy, and congenital heart defects. Lastly, we focus on a study that leverages transcription factor biology to therapeutically modulate heart rhythm.
