What this research studies

Our hearts rely on electrical signals, and tiny channels in heart cells, called SK channels, play a key role in these signals. This project aims to better understand how these SK channels work in both healthy and diseased hearts. We know that SK channels are involved in heart rhythm problems like atrial fibrillation and are more active in heart failure, but we need to learn more about their exact role. By combining laboratory experiments and computer models, this work seeks to clarify how these channels contribute to heart conditions.

Who could benefit from this research

Good fit: Patients with heart rhythm disorders like atrial fibrillation or heart failure may eventually benefit from the discoveries made in this foundational research.

Not a fit: Patients seeking immediate treatment options will not directly benefit from this basic science research, as it focuses on fundamental understanding.

Why it matters

Potential benefit: If successful, this work could lead to new ways to treat common heart rhythm disorders and heart failure by targeting these specific channels.

How similar studies have performed: Previous studies have shown the important roles of SK channels in the heart, but there are still unanswered questions and seemingly conflicting findings that this project aims to resolve.
