Atrial Fibrillation (AFib) vs. Ventricular Fibrillation (VFib) Topic Guide

Arrhythmias or heart rhythm disorders are conditions that causes changes in the normal heartbeat. There are numerous types of arrhythmias, for example, supraventricular tachycardia, sinus sick syndrome, atrial fibrillation, atrial flutter, and ventricular fibrillation. Signs and symptoms of an arrhythmia may include: Chest pain or discomfort Shortness of breath Palpitations Racing heart sensation Treatment for arrhythmias depend upon the cause.

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.

Chest pain has a variety of noncardiac and cardiac causes, some of which can be very serious. Signs and symptoms of chest pain may include burning, squeezing, or heaviness in the chest. Atherosclerosis, angina, lung tumors, chest trauma, abdominal pain, and gastric reflux are just a few potential causes of chest pain. Chest pain is diagnosed by taking the patient history and performing a physical exam. Blood work, imaging tests, and an exercise stress test may be ordered. The treatment and prognosis of chest pain depends on the underlying cause.

Dizziness may be a minor problem, or could be something life-threatening. Causes of dizziness include high blood pressure, low blood pressure, heart problems, conditions of the brain, medications, metabolic conditions, aging, other illnesses or conditions, or psychiatric conditions.

Coronary heart disease (CHD) is a group of different types of heart disease. Symptoms of heart disease depend on the cause and inclue chest pain or angina, shortness of breath, palpitations, and dizziness. Many conditions causes heart disease, for example, genetics, obesity, high cholesterol, and smoking. Treatment for heart disease depend on the cause and include diet and other lifestyle changes, medications, procedures, and surgery. The prognosis (outlook) and life span for someone with heart disease varies depending on the cause.

High blood pressure (hypertension) may be present in an individual, without any symptoms. Thus, it is called the "silent killer." Causes of high blood pressure include heart disease, kidney disease, tumors, birth control, alcohol, thyroid dysfunction, and birth control pills.Treatment of high blood pressure is generally through diet, exercise, and medication if necessary.

Some factors such as genetics are uncontrollable for having high cholesterol. You can lower your cholesterol levels naturally with lifestyle changes such as weight loss and control, exercise, diet, and quitting smoking. If these measures don't lower cholesterol enough a person may need to take cholesterol medications.

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.
