Site Information
mayoclinichealthsystem.org
Link authority for mayoclinichealthsystem.org (registrable domain: mayoclinichealthsystem.org) from the Common Crawl web graph: PageRank and harmonic centrality history since 2017, current scores, and the site's top backlink sources.
Link authority data (PageRank, harmonic centrality) and backlinks come from the Common Crawl web graph.
Current Scores
Web-graph authority (0-100)
Domain scores measure mayoclinichealthsystem.org as a whole: every subdomain's links rolled up into one node of Common Crawl's domain-level web graph. Host scores measure the exact hostname mayoclinichealthsystem.org. WWW scores cover the www variant of that hostname, which the graph tracks as its own entry since January 2026 (before that, www and bare host were merged). A big gap between domain and host usually means the domain's authority lives on other subdomains. PageRank is link-endorsement authority: how much weight the sites linking here carry themselves. Harmonic centrality measures reach: how close this site sits to the rest of the web when following links, which favors broadly connected sites over ones boosted by a few heavy linkers. All are normalized 0 to 100 within each crawl snapshot; a dash means that series does not exist for this site.

While occasional skipped beats may be harmless, symptoms like weakness, fatigue, shortness of breath or chest discomfort could signal a heart rhythm problem such as atrial fibrillation (Afib).\n\u0026ldquo;Afib is a common heart rhythm disorder that can cause an irregular and often rapid heartbeat,\u0026rdquo; says Mayo Clinic Health System cardiologist Divya Korpu, M.B.B.S. \u0026ldquo;It can cause symptoms such as palpitations, fatigue, weakness, shortness of breath, dizziness or chest discomfort. Recognizing these symptoms and knowing when to seek care can help protect your heart health.\u0026rdquo;\nCommon symptoms of Afib and irregular heartbeat\nAfib symptoms often start subtly but can become serious over time. \nYou might notice:\n\n A fluttering or pounding heartbeat\n Shortness of breath, even at rest\n Fatigue or weakness\n Dizziness or fainting\n Chest discomfort\n\nWondering what Afib feels like? Many describe it as a rapid, irregular thumping in the chest, like your heart is \u0026ldquo;out of sync.\u0026rdquo; Episodes can last minutes or hours and may come and go.\nIrregular heartbeat symptoms can include similar sensations: skipped beats, racing heart or a slow, uneven rhythm. Tachycardia symptoms \u0026mdash; when the heart beats too fast\u0026mdash;may cause palpitations, lightheadedness and sometimes fainting.\nSome people with Afib have no noticeable symptoms. In these cases, the condition may be discovered during a routine exam or after a complication such as a stroke.\nIs an irregular heartbeat dangerous?\nNot all irregular rhythms are harmful, but Afib can increase your risk of stroke and heart failure. In Afib, the upper chambers (atria) of the heart beat irregularly. This can allow blood to pool in the atria, increasing the risk of clot formation. These clots can travel to the brain and cause a stroke.\nIf your heart beats too fast for too long, the heart muscle can weaken, leading to heart failure. Because complications can develop, symptoms should be evaluated by a healthcare professional. \nWhen to seek care\nCall your healthcare team or seek emergency care if you experience:\n\n Sudden chest pain or pressure\n Severe shortness of breath\n Fainting or near-fainting episodes\n A racing or irregular heartbeat that doesn\u0026rsquo;t resolve quickly - especially if accompanied by chest pain, shortness of breath or fainting\n\nEven mild symptoms, like occasional fluttering or fatigue, deserve attention. Early diagnosis makes treatment easier and reduces complications.\nWhat causes Afib and irregular heartbeat?\nSeveral factors can trigger rhythm problems, including:\n\n High blood pressure\n Sleep apnea\n Diabetes\n Thyroid issues\n Excess alcohol use\n Heart valve disease\n Obesity\n Recent illness or surgery\n Coronary artery disease or prior heart attacks\n\nSometimes Afib occurs without an obvious cause. That\u0026rsquo;s why regular checkups and heart health monitoring are essential.\nHow Afib is diagnosed\nIf your provider suspects Afib, an electrocardiogram (ECG or EKG) can confirm the diagnosis. Today, some FDA-approved wearable devices, like smartwatches, can detect Afib. However, a medical evaluation and ECG are required to confirm the diagnosis. Additional tests may check for underlying conditions such as thyroid disease or diabetes.\nBottom line\nIf you\u0026rsquo;re wondering, \u0026ldquo;Is irregular heartbeat dangerous?\u0026rdquo;\u0026mdash; the answer is yes, it can be. \n\u0026ldquo;Do not ignore symptoms such as palpitations, fatigue, weakness, shortness of breath, dizziness, fainting or chest pain,\u0026rdquo; says Dr. Korpu. \u0026ldquo;Make an appointment with a cardiologist if symptoms are new or recurrent. Seek emergency care for chest pain, fainting or severe shortness of breath.\u0026rdquo;\nYour heart health matters, and early care can make all the difference.\nDepending on your individual condition, treatment options may include:\n\n Medication to control heart rate or rhythm \n Blood thinners to reduce the risk of stroke\n Cardioversion or catheter ablation\n\nReady to take the next step?\nExplore treatment options for heart rhythm disorders.\nDivya Korpu, M.B.B.S., is a cardiologist with Mayo Clinic Health System in Eau Claire, WI."}

While it often starts as mild irritation, pink eye can be uncomfortable and, in some cases, contagious. Knowing the symptoms, understanding what causes pink eye and recognizing when to seek care can help protect your eye health and reduce the risk of spreading infection to others.\nAccess virtual care 24/7 with Primary Care On Demand through your patient portal on a computer or any mobile device via the Mayo Clinic app wherever you are in Minnesota, Iowa and Wisconsin. Available 24/7/365 for patients age three and older.\nWhat is pink eye?\nPink eye occurs when the thin, clear membrane lining the eyelid and covering the white part of the eye becomes inflamed. When this happens, small blood vessels become more visible, giving the eye a pink or reddish appearance.\nPink eye can have several causes. The most common cause is a viral infection, but it can also result from bacteria or allergies. In babies, blocked tear ducts may lead to similar symptoms. Because some forms of pink eye are contagious, early diagnosis and simple precautions can help limit its spread at home, school or work.\nCommon pink eye symptoms\nSymptoms of pink eye can vary depending on the cause, but many people experience one or more of the following:\n\n Redness in one or both eyes\n Itching, burning or a gritty feeling\n Discharge that may cause the eyelids to stick together, especially overnight\n Excess tearing\n Sensitivity to light\n\nSymptoms may start in one eye and spread to the other, particularly with viral or bacterial conjunctivitis. Allergic pink eye often affects both eyes at the same time and may occur along with sneezing or nasal congestion.\nIf you are unsure what is causing your symptoms, a healthcare professional can help determine whether treatment is needed.\nWhen to seek urgent care for pink eye\nMost cases of pink eye are mild and improve with basic care or time. However, some symptoms may signal a more serious eye condition and should be evaluated promptly.\nSeek urgent care if you experience:\n\n Eye redness with pain\n A sensation that something is in the eye\n Blurred or reduced vision\n Increased sensitivity to light\n Symptoms that worsen or do not improve within 12\u0026nbsp;to 24\u0026nbsp;hours\n\nPeople who wear contact lenses should stop wearing them as soon as symptoms begin. Continuing to wear contacts may increase the risk of complications.\nHow pink eye spreads and how to prevent it\nViral and bacterial pink eye can spread easily through direct contact. Good hygiene plays an important role in prevention.\nSteps that can help reduce the risk of spreading pink eye include:\n\n Avoid touching or rubbing the eyes\n Wash hands often with soap and water\n Use clean towels and washcloths\n Avoid sharing personal items such as towels, washcloths or eye makeup\n Replace old eye cosmetics, including mascara\n Change pillowcases regularly\n\nThese steps are especially important in households with children, shared living spaces and workplaces where close contact is common.\nGetting care for pink eye\nPink eye is common, but it should not be ignored. Understanding the symptoms, knowing when to seek care and taking steps to prevent spread can help protect your vision and the health of those around you.\nIf you think you may have pink eye, talking with a healthcare provider can help you understand what is causing your symptoms and what treatment, if any, is appropriate. In many cases, pink eye can be evaluated through a virtual visit.\nReady to feel better, faster?\nDon\u0026rsquo;t wait for symptoms to disrupt your life.

Web-Graph History
Authority over time
Every Common Crawl web-graph release since 2017, roughly quarterly. The domain series goes back to 2017; Common Crawl only began publishing the host-level graph in 2020, so host lines start there. Click a legend entry to show or hide that line. Flat lines are normal for established sites; watch for sustained rises or drops, which track real gains or losses in who links here.
A note on www: through the end of 2025 the source web graph merged www and non-www hostnames into the bare name, so one host line covers both. Starting in January 2026 the graph splits them into separate entries, which is why www can carry its own scores going forward.
Backlink Data
Backlink counts
Unique linking domains seen in Common Crawl's link graphs. This is a different dataset than the 0-100 authority scores above: these are raw counts, host-level for mayoclinichealthsystem.org and domain-level for mayoclinichealthsystem.org with all its subdomains combined. Common Crawl covers a large sample of the web, not all of it, so treat counts as comparable between sites rather than absolute totals.
