Various techniques help heal ailing heart
Once there, medical professionals discovered the Osseo woman had an irregular heart rhythm.
Before fainting, the longtime elementary art teacher in the Osseo-Fairchild school district had been tired, but she hadn't thought much about it. She had no history of heart problems.
Referred to the Cardiac Center at Mayo Clinic Health System in Eau Claire, Gregory saw Dr. John Rozich, a cardiologist, and nurse practitioner Mona Howard. Rozich implanted a loop recorder monitor under Gregory's skin to capture information about her abnormal heart rhythm.
Gregory was diagnosed with atrial fibrillation, an irregular and often rapid heart rate that commonly causes poor blood flow to the body.
During atrial fibrillation, the heart's two upper chambers — the atria — beat chaotically and irregularly, out of coordination with the two lower chambers — the ventricles -_of the heart.
Left untreated, atrial fibrillation can lead to stroke or heart failure.
"It's a debilitating disease that significantly can affect the quality of life," said Dr. Arturo Valverde, an electrophysiologist at Mayo Clinic Health System in Eau Claire.
Electrophysiologists are cardiologists with additional training in the diagnosis and treatment of abnormal heart rhythms.
About 2.2 million Americans have atrial fibrillation, according to WebMD.com. Dr. Mahmoud Sharaf, an interventional cardiologist with the Eau Claire Heart Institute, expects to see the prevalence of the condition increase as the population ages.
Age is one risk factor for atrial fibrillation, physicians said. Others include heart disease, high blood pressure and family history.
Gregory, now 56, has a family history of heart disease and high blood pressure.
In addition, the loop recorder showed that she developed a very slow heart rate at times.
Several months after Gregory had the loop recorder implanted, Rozich replaced it with a pacemaker, which treats slow heart rhythm but does not treat atrial fibrillation. Her A-fib symptoms continued.

Measuring Cardiac Rhythm While Training
A cardiac rhythm is the manner by which the heart beats, or is the rhythm pattern in the sequence of heart beats. The rhythm may change if there is a heart disease, or something is wrong with the heart’s electrical system in which case the heart does not beat regularly. This irregular beating results in a cardiac rhythm disorder which is called arrhythmia , which is caused by a coronary heart disease but also by heart valve problems or high blood pressure. The other causes of rhythm disorder may include physical or emotional stress, infection or fever, thyroid disease, anemia , drugs and such other stimulants as tobacco, caffeine, cocaine, alcohol, amphetamines and certain prescription medicines. The two most common types of abnormal cardiac rhythm are the sinus bradycardia and sinus tachycardia. Sinus bradycardia has a heart rate of lower than 50 beats per minute, while sinus tachycardia the heart rate is greater than 100 beats per minute. Cardiac rhythm disorders can become life-threatening and therefore, there is need for the heart rhythm to be diagnosed, measured and managed. Abnormal rhythms do not always cause symptoms but they can be determined efficiently by a device called electro-cardiogram (ECG) which can also detect an arrhythmia and measure the pulse beats. If you are on an exercise or training routine, the greater is your need to measure your heart rhythm. This will help you see how well your heart is working with your physical activity and find some symptoms of possible irregular heartbeat. If, however, you do not have an immediate access to an ECG, you can measure your own cardiac rhythm in your own way. While you are at rest, you can find your carotid artery that pulsates with your heartbeat. This artery can be found under your jawbone. Once you find the artery, place your middle and index fingers on it as it pulsates with the heart.
