Common causes of Tachycardia include: Heart-related conditions such as high blood pressure (hypertension) Poor blood supply to the heart muscle due to coronary artery disease (atherosclerosis), heart valve disease, heart failure, heart muscle disease (cardiomyopathy), tumors, or infections.

A normal pulse beats in a steady, regular rhythm. However, in some people this rhythm is uneven, or ‘jumps about’. This is known as an irregular pulse.

Rapid, fast heartbeat at rest could be caused by stress, caffeine, alcohol, tobacco, thyroid pills, cold medication, asthma drugs or diet pills. Sometimes low blood pressure , heart disease and some heart rhythm conditions can cause rapid heartbeat, too.

These include: Coronary artery disease, other heart problems and previous heart surgery. Narrowed heart arteries, a heart attack, abnormal heart valves, prior heart surgery, heart failure, cardiomyopathy and other heart damage are risk factors for almost any kind of arrhythmia.

People with harmless arrhythmias can live healthy lives and usually don’t need treatment for their arrhythmias. Even people with serious types of arrhythmia are often treated successfully and lead normal lives.

“With a heart monitor we can usually determine if it is really a panic attack or an arrhythmia.” One way to determine if what you’re experiencing is atrial fibrillation or anxiety is to understand both sets of symptoms.

Anxiety causes the release of stress hormones in the body. These hormones trigger an increase in the heart rate and a narrowing of the blood vessels. Both of these changes cause blood pressure to rise, sometimes dramatically.

Common anxiety signs and symptoms include:

• Feeling nervous, restless or tense.
• Having a sense of impending danger, panic or doom.
• Having an increased heart rate.
• Breathing rapidly (hyperventilation)
• Sweating.
• Trembling.
• Feeling weak or tired.
• Trouble concentrating or thinking about anything other than the present worry.

Follow the 3-3-3 rule. Then, name three sounds you hear. Finally, move three parts of your body — your ankle, fingers, or arm. Whenever you feel your brain going 100 miles per hour, this mental trick can help center your mind, bringing you back to the present moment, Chansky says.

Rather than trying to stop or get rid of an anxious thought, give yourself permission to have it, but put off dwelling on it until later.

1. Create a “worry period.” Choose a set time and place for worrying.
2. Write down your worries.
3. Go over your “worry list” during the worry period.

Try these when you feel nauseated:

1. Eat a small amount of something dry, like plain crackers or plain bread.
2. Slowly sip water or something clear and cold.
3. If you’re wearing something tight, change into clothing that doesn’t restrict your stomach.
4. Try to calm yourself by taking long, deep breaths.

Many anxious children and adults develop physical symptoms related to their anxiety. These can include dizziness, tummy pains, headaches and vomiting, as is the case with your daughter. Often, when physical symptoms happen, this can add a new layer to the worrying.

Brain shivers or zaps. Most often, this bizarre sensation is caused by antidepressants or withdrawal from them. However, sometimes it’s associated with anxiety. Brain shivers can range from mild to severe and feel different from person-to-person, though they usually last only a brief time.

The stress from anxiety can cause feelings of genuine sickness. These feelings are often very similar to the way physical illnesses make you feel. Your stomach can feel like it’s rumbling and you may even feel nauseated. Feeling sick may be a sign that you’ve fallen ill, but it can also be a sign of anxiety.

Feeling run down, getting sick often, or feeling nauseous always is often explained by a lack of sleep, poor diet, anxiety or stress. However, it could also be a sign of pregnancy or chronic illness.

You might worry about things like health, money, or family problems. But people with generalized anxiety disorder (GAD) feel extremely worried or feel nervous about these and other things—even when there is little or no reason to worry about them.

On the other hand, the ‘overthinking’ about traumatic events might explain the negative symptoms of schizophrenia (such as apathy, lack of motivation, not talking). There has already been some work on trauma as a cause of schizophrenia, as well as a book on overthinking and schizophrenia.
