What is Heart Arrhythmia?
Heart arrhythmia (also known as arrhythmia, dysrhythmia, or irregular heartbeat) is a group of conditions in which the heart beats with an irregular or abnormal rhythm. It can cause the heart to beat too slowly, too quickly, or erratically. Heart arrhythmia can cause symptoms such as dizziness, fatigue, chest pain, shortness of breath, and palpitations. It can also lead to more serious complications such as stroke, heart failure, and even sudden death.
What Causes Heart Arrhythmia?
Heart arrhythmia can be caused by a variety of factors including genetics, underlying medical conditions, lifestyle factors, and medications. Common causes of heart arrhythmia include coronary artery disease, high blood pressure, diabetes, thyroid disease, alcohol or drug abuse, and certain medications.
How Is Heart Arrhythmia Diagnosed?
Heart arrhythmia can be diagnosed through a physical exam and a review of your medical history. Your doctor may also order tests such as an electrocardiogram (ECG), an echocardiogram, or a Holter monitor to help diagnose the condition.
How Is Heart Arrhythmia Treated?
Treatment for heart arrhythmia depends on the type of arrhythmia and the severity of the condition. Treatment may include lifestyle changes, medications, or medical procedures. Common treatments for heart arrhythmia include medications to control heart rate and rhythm, catheter ablation to destroy areas of the heart that cause arrhythmias, and implantation of a pacemaker or defibrillator.
