Palpitations are uncomfortable sensations of the heart beating hard, rapidly, or irregularly. Some types of palpitations are benign, while others are more serious. Palpitations are diagnosed by taking the patient history and by performing an EKG or heart monitoring along with blood tests. An electrophysiology study may also be performed. Treatment of palpitations may include lifestyle changes, medication, ablation, or implantation of a pacemaker. The prognosis if palpitations depends on the underlying cause.
Those who experience panic attacks are often nervous about having additional episodes. To avoid having a panic attack in a public space, they may avoid places like shopping malls or other crowded spots where previous incidents may have occurred or places that they fear will not allow them immediate access to help, such as an airplane or movie theater. This avoidance when severe may lead to agoraphobia, the inability to leave familiar, safe surroundings because of intense fear and anxiety about having a panic attack outside the home.
Anxiety disorders fall into a set of distinct diagnoses, depending upon the symptoms and severity of the anxiety the person experiences. Anxiety disorders share the anticipation of a future threat, but differ in the types of situations or objects that induce fear or avoidance behavior. Different types of anxiety disorder also have different types of unhealthy thoughts associated with them.

The philosopher Søren Kierkegaard, in The Concept of Anxiety (1844), described anxiety or dread associated with the "dizziness of freedom" and suggested the possibility for positive resolution of anxiety through the self-conscious exercise of responsibility and choosing. In Art and Artist (1932), the psychologist Otto Rank wrote that the psychological trauma of birth was the pre-eminent human symbol of existential anxiety and encompasses the creative person's simultaneous fear of – and desire for – separation, individuation, and differentiation.
Genetics and family history (e.g., parental anxiety) may predispose an individual for an increased risk of an anxiety disorder, but generally external stimuli will trigger its onset or exacerbation.[57] Genetic differences account for about 43% of variance in panic disorder and 28% in generalized anxiety disorder.[58] Although single genes are neither necessary nor sufficient for anxiety by themselves, several gene polymorphisms have been found to correlate with anxiety: PLXNA2, SERT, CRH, COMT and BDNF.[59][60][61] Several of these genes influence neurotransmitters (such as serotonin and norepinephrine) and hormones (such as cortisol) which are implicated in anxiety. The epigenetic signature of at least one of these genes BDNF has also been associated with anxiety and specific patterns of neural activity.[62]
What is depression and what can I do about it? Depression is a mood disorder characterized by low mood, a feeling of sadness, and a general loss of interest in things. Depression is not a short-term problem and can last for months. There are many types of depression, and it is essential to see a doctor or mental health therapist for correct diagnosis and treatment.

We all tend to avoid certain things or situations that make us uncomfortable or even fearful. But for someone with a phobia, certain places, events or objects create powerful reactions of strong, irrational fear. Most people with specific phobias have several things that can trigger those reactions; to avoid panic, they will work hard to avoid their triggers. Depending on the type and number of triggers, attempts to control fear can take over a person’s life.

People often fear the worst when they're having an anxiety attack. Most of the time, there’s no underlying physical problem, such as a real heart attack. But you should get the medical all clear if you have repeat anxiety attacks, just to be sure you don’t need additional treatment. Then find a cognitive behavioral therapist with experience treating anxiety to help you through.
Antidepressants are used to treat depression, but they can also be helpful for treating anxiety disorders. They may help improve the way your brain uses certain chemicals that control mood or stress. You may need to try several different antidepressant medicines before finding the one that improves your symptoms and has manageable side effects. A medication that has helped you or a close family member in the past will often be considered.
If you have a debilitating fear of being seen negatively by others and humiliated in public, you may have social anxiety disorder, also known as social phobia. Social anxiety disorder can be thought of as extreme shyness. In severe cases, social situations are avoided altogether. Performance anxiety (better known as stage fright) is the most common type of social phobia.
People who have repeated, persistent attacks or feel severe anxiety about having another attack are said to have panic disorder. Panic disorder is strikingly different from other types of anxiety disorders in that panic attacks are often sudden and unprovoked.[18] However, panic attacks experienced by those with panic disorder may also be linked to or heightened by certain places or situations, making daily life difficult.[19]
Once someone has had a panic attack, he or she may develop irrational fears, called phobias, about the situations they are in during the attacks and begin to avoid them. That, in turn, may reach the point where the mere idea of doing things that preceded the first panic attack triggers terror or dread of future panic attacks, resulting in the individual with panic disorder being unable to drive or even step out of the house. If this occurs, the person is considered to have panic disorder with agoraphobia.
These attacks are a symptom of panic disorder, a type of anxiety disorder that affects some 2.4 million U.S. adults. The disorder most often begins during the late teens and early adulthood and strikes twice as many American women as men. No one knows what causes panic disorder, though researchers suspect a combination of biological and environmental factors, including family history (panic disorder seems to run in families), stressful life events, drug and alcohol abuse, and thinking patterns that exaggerate normal physical reactions.
Many neurotransmitters are affected when the body is under the increased stress and anxiety that accompany a panic attack. Some include serotonin, GABA (gamma-aminobutyric acid), dopamine, norepinephrine and glutamate. More research into how these neurotransmitters interact with one another during a panic attack is needed to make any solid conclusions, however.
Poverty and low education level tend to be associated with anxiety, but it is unclear if those factors cause or are caused by anxiety. While some statistics suggest that disadvantaged ethnic minorities tend to suffer from internalizing disorders like panic disorder less often than the majority population in the United States, other research shows that may be the result of differences in how ethnic groups interpret and discuss signs and symptoms of intense fright, like panic attacks. Also, panic and other anxiety disorders are thought to persist more for some ethnic minorities in the United States. Difficulties the examiner may have in appropriately recognizing and understanding ethnic differences in symptom expression is also thought to play a role in ethnic differences in the reported frequency of panic and other internalizing disorders.
Butterflies in your stomach before an important event? Worried about how you will meet a deadline? Nervous about a medical or dental procedure? If so, you are like most people, for whom some worry about major events (like having a child, taking an exam, or buying a house), and/or practical issues (like money or health conditions), is a normal part of life. Similarly, it is not uncommon to have fears about certain things (like spiders, injections, or heights) that cause you to feel some fear, worry, and/or apprehension. For example, many people get startled and feel nervous when they see a snake or a large insect. People can differ in what causes them to feel anxious, but almost everyone experiences some anxiety in the course of their life.
Although beta-blockers are most often used to treat high blood pressure, they can also be used to help relieve the physical symptoms of anxiety, such as rapid heartbeat, shaking, trembling, and blushing. These medications, when taken for a short period of time, can help people keep physical symptoms under control. They can also be used “as needed” to reduce acute anxiety, including as a preventive intervention for some predictable forms of performance anxieties.
