A new study from Ohio State University helps explain why women typically have faster heartbeats than men and why men are more prone to irregular heart rhythms like atrial fibrillation (AFib).
Researchers found that the heart’s natural pacemaker, called the sinoatrial node (SAN), operates differently at the genetic level between the sexes.
The SAN controls the heartbeat, and this study discovered that women’s hearts express higher levels of genes, such as TBX3 and HCN1, which promote faster heart rates.
In contrast, men’s hearts show more gene activity linked to inflammation and collagen production, which can disrupt electrical signals and raise the risk of arrhythmias like AFib.
These findings provide important insights into sex-specific heart health and may guide more personalized treatments for heart rhythm disorders.
Understanding these differences could improve how doctors prevent and manage conditions that affect millions, such as heart failure and abnormal heart rhythms.
Maintaining heart health is crucial for everyone. Regular exercise, a balanced diet low in processed foods and rich in fruits and vegetables, and managing stress can support a healthy heartbeat.
If you experience palpitations, irregular pulses, or other heart symptoms, seek medical advice early for proper diagnosis and care.
