The Quincke Fingernail Sign

The Quincke sign is the name given to the capillary pulsations visible upon lightly pressing the tip of the fingernail bed. This sign was named after a physician from Germany who first coined the term in 1868, Dr. Heinrich Quincke. He also contributed to several other noteworthy medical advances, such as identifying the angioedema and his work on the lumbar puncture technique. The Quincke sign results from an increased systolic stroke volume, a widened pulse pressure, and a rapid decrease in pressure in the arteries.

Symptoms of Severe Aortic Regurgitation

Typically, the condition develops over time, with symptoms often not arising for years. However, sometimes it hits suddenly, usually due to a valve infection. As aortic valve regurgitation worsens, symptoms can also include shortness of breath, particularly during exercise or when lying down.

People also experience increased tiredness and weakness, especially after any sort of physical activity. Irregular heartbeats, lightheadedness, or fainting may also occur. Pain or tightness in the chest is also common among patients, especially after exercise. Additionally, as the condition progresses, some people may experience heart palpitations and swelling in the ankles and feet.

When Should You See A Doctor

The Quincke fingernail sign is among more than 30 reported signs of severe aortic regurgitation. If you are experiencing any of the above symptoms, you are advised to book an appointment with your doctor immediately since these are potential signs of a serious heart problem.

Aortic regurgitation diagnosis usually involves undergoing certain tests that measure your heart’s performance, in addition to taking scans that provide insight into its structure. Your treatment will vary depending on the severity of your condition. Patients with milder conditions will likely need to return for regular check-ups, and other patients may be prescribed medications to combat potential side effects.

The Bottom Line on Your Fingernails

There are many signs that may indicate that you have aortic regurgitation. The Quimcke fingernail sign is an easily observable indication as to whether you have this condition or not. If you want to check for Quinckes sign yourself, gently press on your fingernail then release it.

Now observe the nail bed under decent lighting conditions. Look out for rhythmic pulsations or alternating redness and paleness. This could indicate the presence of aortic regurgitation. However, it should not be considered a definitive diagnostic tool, but rather a sign to see your doctor.
