Different tests for Arrhytmias

To diagnose a heart arrhythmia, your doctor may ask about — or test for — conditions that may trigger your arrhythmia, such as heart disease or a problem with your thyroid gland. Your doctor may also perform heart-monitoring tests specific to arrhythmias. These may include:

Electrocardiogram (ECG). During an ECG, sensors (electrodes) that can detect the electrical activity of your heart are attached to your chest and sometimes to your limbs. An ECG measures the timing and duration of each electrical phase in your heartbeat.
Holter monitor. This portable ECG device can be worn for a day or more to record your heart’s activity as you go about your routine.
Event monitor. For sporadic arrhythmias, you keep this portable ECG device at home, attaching it to your body and pressing a button when you have symptoms. This lets your doctor check your heart rhythm at the time of your symptoms.
Echocardiogram. In this noninvasive test, a hand-held device (transducer) placed on your chest uses sound waves to produce images of your heart’s size, structure and motion.

The pain of Angina and similar pains

Angina is relatively common but can be hard to distinguish from other types of chest pain, such as the pain or discomfort of indigestion. If you have unexplained chest pain, seek medical attention right away.

Angina is a type of chest pain caused by reduced blood flow to the heart muscle. Angina is a symptom of coronary artery disease. Angina is typically described as squeezing, pressure, heaviness, tightness or pain in your chest.

Angina, also called angina pectoris, can be a recurring problem or a sudden, acute health concern.

To diagnose angina, your doctor will start by doing a physical exam and perhaps the most accurate would be the Nuclear Stress Test.

How to determine a Severe Asthma Attack?

Determine if the asthma attack is severe. Severe asthma attacks happen less frequently, but are characterized by:
-Wheezing or whistling produced by breathing in and out
-Rapid breathing
-Uncontrollable coughing
-Chest pain or chest tightening
-Difficulty talking
-Anxiety or panic
-Pale face and blue lips or fingers
-Persistence of symptoms despite use of asthma medications

In the case of a severe asthma attack, call emergency medical services. Most of the time, severe attacks will progress with few warnings. If signs do occur, it is important to treat them immediately, so that they do not lead to severe attacks.






What are the signs of a Stroke?

The most common symptoms of a stroke are:

-Weakness or numbness of the face, arm or leg on one side of the body.
-Loss of vision or dimming (like a curtain falling) in one or both eyes.
-Loss of speech, difficulty talking or understanding what others are saying.
-Sudden, severe headache with no known cause.
-Loss of balance, unstable walking, usually combined with another symptom.

A stroke, sometimes called a “brain attack,” occurs when blood flow to an area in the brain is cut off. The brain cells, deprived of the oxygen and glucose needed to survive, die. If not caught early, permanent brain damage can result.






How Common is Silent Ischemia and Who is at Risk?

The American Heart Association estimates that 3 to 4 million Americans have episodes of silent ischemia. People who have had previous heart attacks or those who have diabetes are especially at risk for developing silent ischemia. Heart muscle disease (cardiomyopathy) caused by silent ischemia is among the more common causes of heart failure in the United States.
Major risk factors include:
• Previous heart attack
• Coronary artery disease
• Diabetes
• High blood pressure (hypertension)
• Cardiomyopathy
• Obesity
• Smoking
• Alcohol and drug abuse

SymptomsSilent ischemia has no symptoms. Researchers have found that patients who have noticeable chest pain may also have episodes of silent ischemia.






How to manage Peripheral Artery Disease

Many people can manage the symptoms of peripheral artery disease and stop the progression of the disease through lifestyle changes, especially quitting smoking. To stabilize or improve PAD:
Stop smoking. Smoking contributes to constriction and damage of your arteries and is a significant risk factor for the development and worsening of PAD. If you smoke, quitting is the most important thing you can do to reduce your risk of complications
Exercise. This is a key component. Success in treatment of PAD is often measured by how far you can walk without pain. Proper exercise helps condition your muscles to use oxygen more efficiently. Your doctor can help you develop an appropriate exercise plan.
Eat a healthy diet. A heart-healthy diet low in saturated fat can help control your blood pressure and cholesterol levels, which contribute to atherosclerosis.
Avoid certain cold medications. Over-the-counter cold remedies that contain pseudoephedrine (Advil Cold & Sinus, Aleve Sinus & Headache, Claritin-D, Sudafed, Tylenol Cold, Zyrtec-D, others) constrict your blood vessels and may increase your PAD symptoms.






Sudden Death in sports occurs mostly in Men

Overall, sudden cardiac death isn’t the most common thing to happen during a sporting event. But for French men, at least, a little extra screening before participating could be life-saving because, according to a new study, men have an almost 20 times higher risk of sudden death than women.

“Compared with men, we found a lower incidence of sports-related sudden death in women and differences by age and sport,” the researchers wrote. “The observed sex differences may be a result of variation in the rate of sports participation between men and women.”

To account for that disparity, the researchers measured sudden cardiac death incidents per million participants. They also counted only participants who were engaging in moderate to vigorous intensity exercise, and also based their results on the three sports most popular among French women: cycling, jogging, and swimming.

Sudden cardiac death occurs when the heart stops beating unexpectedly. Also known as sudden cardiac arrest (SCA), it’s much different from a heart attack, which occurs when blood flow to the heart muscle is blocked. Sometimes, the electrical impulses that control the heart’s beating can lose rhythm — called arrhythmia — or sometimes they stop altogether. This is when SCA occurs.






Breakfast helps your Healthy Heart

Men who skip breakfast or indulge in late-night cravings might be more at risk for a heart attack and coronary heart disease, according to a new study published in the journal Circulation.

While studies have long pointed to the idea that breakfast is important for children, little research has been done on whether “the most important meal of the day” is really that critical for adults.

“Skipping breakfast may lead to one or more risk factors, including obesity, high blood pressure, high cholesterol and diabetes, which may in turn lead to a heart attack over time,” said lead author Dr. Leah Cahill, a postdoctoral research fellow in the Department of Nutrition at Harvard School of Public Health.






Are you a Diabetic? Your veggies are served!

Add plenty of non-starchy vegetables, such as broccoli, spinach and green beans, to your diet, diabetes experts say. These foods are high in fiber and low in carbohydrates, which make them ideal for people with diabetes.
In contrast, starchy vegetables include peas, potatoes, sweet potatoes, broad beans, corn and butternut squash. There’s no need to cut them from the diet. They do give us additional nutrients. We want to maintain balance, but because starchy vegetables have more carbohydrates and raise blood sugar more, it’s important to stick to proper portion sizes.

There’s evidence, too, that vegetables are healthy for people with diabetes.

Researchers have found that a low-fat vegan diet may help type 2 diabetes patients to better manage their disease. In a study in the US publication Diabetes Care, 43% of people with type 2 diabetes who followed a low-fat vegan diet for 22 weeks reduced the need to take diabetes medications. Because people with diabetes are more prone to heart disease, eating with heart health in mind matters as much as blood sugar control.






What is a sweat test related with ANS?

Sweat tests evaluate a particular part of the autonomic nervous system. The brain increases sweating by directing an increase in sympathetic nervous system traffic to sweat glands in the skin. The chemical messenger, acetyl-choline, is released, which acts on the sweat glands to stimulate the production of sweat. The QSART is a special form of sweat test. It tests the ability of sympathetic nerve terminals in the skin to release acetylcholine and increase sweat production. A drug is applied to a nearby patch of skin. This evokes sweating at the site, but it also allows the body to release its own acetyl-choline, resulting in sweat production. If a person had a loss of sympathetic nerve terminals that release acetyl-choline, applying the patches would not lead to increased sweating. By this sort of neuropharmacologic test, doctors can distinguish sympathetic cholinergic failure due to loss of cholinergic terminals from failure due to abnormal regulation of sympathetic nerve traffic to intact cholinergic terminals.
