Electrophysiology focuses on understanding and treating irregular heart rhythms or arrhythmias. Through specialized testing, cardiologists study the heart's electrical activity to pinpoint the source of rhythm disturbances. Treatments can include medication management, implantation of pacemakers or defibrillators, and catheter ablation to correct abnormal electrical pathways. By restoring normal heart rhythm, electrophysiology helps prevent complications like fainting spells, stroke, and heart failure, improving patients' overall well-being. This field continually advances with innovative technologies and techniques, offering precise diagnoses and tailored treatments to address a wide range of arrhythmias and enhance heart health.
