Among individuals without known heart disease, arrhythmias are generally random, isolated occurrences that do not carry any significance. However, a discussion with a physician is advised.
A variety of heart diseases cause arrhythmias. Heart disease can refer to patients with coronary artery disease, heart valve problems, heart failure, or disorders with heart conduction or high blood pressure. Remember, however, that having an arrhythmia does not necessarily mean that you have heart disease. Arrhythmias have many causes; sometimes the cause of an arrhythmia is never determined.
Sometimes, conditions other than heart disease may cause or aggravate arrhythmias. These conditions include the following:
Infection or fever
Physical or emotional stress
Diseases such as anemia or thyroid disease
Drugs and other stimulants, such as caffeine, tobacco, alcohol, cocaine, amphetamines, and certain over-the-counter and prescription medications
Certain arrhythmias can be inherited as well
Circulatory System
Circulatory System, or cardiovascular system, in humans, the combined function of the heart, blood, and blood vessels to transport oxygen and nutrients to organs and tissues throughout the body and carry away waste products. Among its vital functions, the circulatory system increases the flow of blood to meet increased energy demands during exercise and regulates body temperature.
