Genetics of sinoatrial node function and heart rate disorders

1 May 2023

Abstract excerpt

The sinoatrial node (SAN) is the primary pacemaker of the mammalian heart, initiating its electrical activation and ensuring that the heart's functional cardiac output meets physiological demand. SAN dysfunction (SND) can cause complex cardiac arrhythmias that can manifest as severe sinus bradycardia, sinus arrest, chronotropic incompetence and increased susceptibility to atrial fibrillation, among other cardiac...
