Mayne's Sign is a clinical indicator used by doctors to help diagnose aortic regurgitation, a condition where the heart's aortic valve doesn't close tightly. This sign involves measuring the difference in blood pressure between the arm and the leg. If the systolic blood pressure in the leg is significantly higher than in the arm, it may suggest aortic regurgitation. Understanding Mayne's Sign can be crucial for early detection and treatment of heart conditions. This blog post will dive into 30 fascinating facts about Mayne's Sign, shedding light on its history, significance, and how it’s used in modern medicine. Whether you're a medical student, a healthcare professional, or just curious about heart health, these facts will provide valuable insights.
Key Takeaways:
- Mayne's Sign is a crucial tool for diagnosing heart conditions. It measures blood pressure differences between limbs, helping doctors detect aortic regurgitation early and improve patient outcomes.
- Despite its age, Mayne's Sign remains relevant in modern medicine. It's a valuable, low-cost diagnostic tool that can be used in emergency settings and routine check-ups, potentially saving lives.

- 04
Mayne's Sign is measured by comparing systolic blood pressure in the arm and the leg. Systolic blood pressure is the pressure in your arteries when your heart beats.
- 05
A significant difference in blood pressure readings indicates a positive Mayne's Sign. Typically, a difference of more than 20 mmHg is considered significant.
- 06
Doctors use a sphygmomanometer to measure blood pressure in both limbs. This device is commonly known as a blood pressure cuff.
Clinical Significance
Mayne's Sign holds great importance in diagnosing and understanding aortic regurgitation.
- 07
A positive Mayne's Sign suggests the presence of aortic regurgitation. This condition can lead to heart failure if not treated promptly.
- 08
Early detection through Mayne's Sign can improve patient outcomes. Timely diagnosis allows for better management and treatment of the condition.
- 09
Mayne's Sign is one of several signs used to diagnose aortic regurgitation. Other signs include Corrigan's pulse and Quincke's sign.
Limitations and Considerations
