Anxiety
Anxiety as a medical condition is characterized by worry, fear, nervousness, shortness of breath, sleep problems and other symptoms. Diarrhea, tremors, and rapid heart rate are some physical symptoms of severe anxiety, which may arise from a mental or physical condition, drug use, or some combination of these causes. Treatment can include medication and psychotherapy. -
Atrial Fibrillation
Atrial fibrillation (AFib) describes a rapid, irregular heart rhythm. The irregular rhythm, or arrhythmia, results from abnormal electrical impulses in the heart. Atrial fibrillation may be treated with medications or surgery. There are many causes of atrial fibrillation, for example, pneumonia, heart disease, alcohol use, and thyroid problems. Symptoms of atrial fibrillation include chest pain and/or angina, nausea, dizziness, and heart palpitations. Atrial fibrillation is managed and treated with medication, medical procedures, and surgery. -
Atrial Flutter
Atrial flutter is a type of arrhythmia, that is, an irregularity in the beating of the heart. Symptoms of atrial flutter include heart palpitations, shortness of breath, anxiety, weakness, and a fluttering feeling in the chest. Causes of atrial flutter include heart disease, hypertension, heart muscle disease, heart abnormalities, substances, and diseases that affect other areas of the body. Treatment of atrial flutter includes defibrillation and medication. -
Automated External Defibrillators (AED)
Automated external defibrillators (AEDs) are used when a person has had a heart attack or sudden cardiac arrest. It is a machine that instructs the user through the steps to defibrillate the victim. As more and more AEDs are placed in public places, more lives are saved from sudden cardiac arrest. -
Congestive Heart Failure
Congestive heart failure (CHF) is a condition in which the heart can't pump enough blood and oxygen to the body's tissues. Learn about symptoms and treatment. -
Electrocardiogram (ECG)
An electrocardiogram (ECG, EKG) is a tool used to assist in diagnosing heart diseases and conditions, for example, atrial and ventricular fibrillation, heart attacks, and heart failure. -
Fainting
Fainting or syncope, is a temporary loss of consciousness. Causes of fainting include vasovagal, situational, postural, cardiac, neurologic, and psychogenic. Treatment of fainting depends on the cause. -
Palpitations
Heart palpitations are an abnormality of the normal heartbeat and rhythm and are a symptom of another disease or problem. Causes of heart palpitations include heart disease or other heart problems (mitral valve prolapse, atrial fibrillation), during pregnancy, perimenopause, menopause, postmenopause, anxiety, emotional stress, stimulants (caffeine, alcohol, drugs), and some over-the-counter and prescription medications. Other symptoms that may accompany heart palpitations include nausea, vomiting, sweating, shortness of breath, and angina (heart pain). Some types of heart palpitations can be fatal, for example, ventricular fibrillation or ventricular tachycardia. -
Stroke
Stroke is a medical emergency. When a person has a stroke, part of the blood supply to the brain is cut off or greatly decreased. There are two main types of stroke, ischemic and hemorrhagic. Stroke symptoms include dizziness, sudden headache, weakness in an arm or leg on the same side, weakness in the muscles of the face, difficulty speaking, vision problems, and more. Treatment of stroke depends on the type and severity of the stroke suffered. -
Sudden Cardiac Arrest
Sudden cardiac arrest (SCA) usually causes death if it is not treated within minutes. Some of the causes of sudden cardiac death include ventricular fibrillation, medication or drug abuse/overdose, heart attack, physical stress, inherited disorders, and changes in the structure of the heart. Automatic external defibrillator (AED), if available is the best immediate treatment for sudden cardiac arrest. -
Supraventricular Tachycardia
Supraventricular tachycardia (SVT, PSVT) is a type of heart rhythm disorder in which the heart beats faster than normal. Learn about symptoms, causes, and treatment.
