flag Scientists find gender differences in heart's pacemaker genes, explaining varied heart rates and risks.

flag Researchers at Ohio State University found that the sinoatrial node, the heart's natural pacemaker, operates differently in men and women due to distinct gene expressions. flag Women have faster heart rates due to genes like TBX3 and HCN1, while men are more prone to heart rhythm disorders like atrial fibrillation due to gene networks linked to inflammation. flag This discovery could lead to more personalized treatments for heart rhythm disorders.
