Electrophysiology Clinical Research & Innovations

Mission Statement

The mission of the Electrophysiology Clinical Research & Innovations program (ECRI) is to create and develop an infrastructure for translational and clinical cardiac arrhythmia research and innovation in order to establish Texas Heart Institute as a nationally and internationally recognized leader in the field of cardiac arrhythmias.


ECRI is focused on design and implementation of ongoing research projects targeting detection, management, and treatment of cardiac arrhythmias and the development of strategies for community-wide cardiovascular disease education.

Ongoing studies include a variety of clinical research topics, as follows:

  • Study of the effects of weight loss supplements on heart rhythm;
  • Identification of important risk factors for development of specific cardiac rhythm disorders (atrial fibrillation) during and after cardiac surgery;
  • Evaluation of a predictive scoring system and possible interventions to mitigate these risks.
EPCI also performs numerous translational and large animal studies to test new drugs, procedures or devices for treatment or prevention of heart rhythm disorders and ECRI investigators developed the first electrophysiology database for Texas Heart Institute.   


Electrophysiology: The biomedical field dealing with the study of electric activity in the body, including that of the heart.

Arrhythmia: Any irregularity in the heart's natural rhythm 

Atrial fibrillation: An abnormal and irregular heart rhythm in which electrical signals are generated chaotically throughout the upper chambers (atria) of the heart.
