Cardiac arrhythmias are abnormal heart rhythms that can occur when the electrical impulses that coordinate heartbeats are not functioning properly. These irregular heartbeats can cause the heart to beat too fast, too slow, or irregularly. This can result in symptoms such as palpitations, dizziness, shortness of breath, or chest pain. Cardiac arrhythmias can be caused by a variety of factors, including genetics, heart disease, high blood pressure, and electrolyte imbalances. Treatment for cardiac arrhythmias may include medications, lifestyle changes, or procedures such as catheter ablation or implantable devices like pacemakers or defibrillators. Research in this area focuses on understanding the mechanisms of arrhythmias, improving diagnostic tools, and developing new treatments to effectively manage and prevent these potentially dangerous heart rhythm disorders.
