Arrhythmia (also called an irregular heartbeat) is a condition in which the heart beats too fast, too slow, or in an uneven rhythm. Normally, the heart’s electrical system controls a steady heartbeat. When these electrical signals don’t work properly, the rhythm becomes abnormal.
Symptoms vary depending on the type but may include palpitations (fluttering or pounding heartbeat), dizziness, shortness of breath, chest discomfort, fatigue, or fainting. Some people may have no symptoms at all.
Underlying heart disease, such as coronary artery disease or a prior heart attack, and high blood pressure can increase the risk. Other important contributors are electrolyte imbalances, thyroid disorders, diabetes, obesity, smoking, and increasing age.
Treatment depends on the type and severity. Options include lifestyle changes, medications, procedures like cardioversion or catheter ablation, pacemakers, or implantable defibrillators. Early diagnosis and medical guidance are important to prevent complications.
