Implication
Refines models of cardiac sodium channel gating; leaves open translation to human arrhythmias.
Key Points
- This research aims to understand the factors influencing the gating behavior of cardiac sodium channels.
- Analyzed sodium channels using high-resolution single-channel recordings.
- Studied channels over a broad range of potentials to observe gating behavior.
- Identified molecular transitions affecting channel opening and closing.
- Channels displayed both complex and simple gating patterns at varying voltages.
- Behavioral diversity linked to balance between two molecular transitions.
- Molecular transitions influence the channels' ability to exit the open state.

Intervention
High-resolution single-channel recordings over a broad range of potentials
O
Outcome
Gating patterns and molecular transitions
The behavioral diversity of cardiac sodium channels can be explained by the balance between two molecular transitions for exiting the open state.
