Research field

Cardiac Electrophysiology

Cardiac electrophysiology studies the electrical impulse generation and propagation that coordinates rhythmic heart contraction, investigating ion channels, gap junctions, and cellular architecture that govern normal sinus rhythm and the molecular defects precipitating arrhythmias. Researchers combine molecular electrophysiology—patch-clamp recordings of individual ion channels—with whole-heart optical imaging, clinical catheter studies, and patient-specific computational models to understand how abnormal electrical circuits arise in atrial fibrillation, ventricular tachycardia, and inherited channelopathies. The field drives direct clinical impact through catheter ablation techniques curing arrhythmias by creating precise lesions in abnormal conduction pathways, and through implantable devices including pacemakers and defibrillators. Translational research connects basic channel biology to drug development for anti-arrhythmic therapies and next-generation cardiac monitoring devices.
