Cardiac Electrophysiology is the study of the electrical activity of the heart. It focuses on how electrical signals control the heart's rhythm and ensure it beats effectively. When these signals are disrupted, it can lead to conditions like arrhythmias, where the heart beats too fast, too slow, or irregularly. Doctors specializing in this field use various tests and procedures, such as electrophysiology studies and catheter ablation, to diagnose and treat these heart rhythm problems. Understanding cardiac electrophysiology helps improve treatments and outcomes for patients with heart conditions, ensuring their hearts function properly.
