URMC / Heart Research Follow-up Program / Digital ECG Holter Laboratory

ECG and Electrophysiology Core Laboratory Services

The Heart Research Follow-up Program (HRFUP) has been involved in electrocardiology research for over 20 years.  The main focus of this research is on ventricular arrhythmias and ventricular repolarization analyses.  The HRFUP ECG core laboratory is prepared to conduct analysis of all types of ECG recordings including standard 12-lead ECG, signal-averaged ECG (SAECG), digital high resolution ECG, and analog or digital long-term 24-hour Holter recordings.  Over several years of conducting the NIH and industry sponsored large clinical studies and trials, the HRFUP has developed expertise in the central coordination and analysis of ECG recordings.

We are pleased to inform you that our research-oriented ECG Core Lab at Heart Research Follow-up Program of Cardiology Unit is broadening the spectrum of its activity. Our ECG Core Lab is actively involved in various clinical and animal ECG studies requiring central management of ECG data acquisition, central reading and analysis of ECGs in various technical forms. The analysis of paper-copy ECGs, with particular emphasis on QT interval evaluation, is our routine activity related to specific research or drug-safety oriented projects. In the current era of digital ECG technology, we are fully operational managing data acquisition and analysis of digital standard 12-lead ECG and 24-hour Holter ECG recordings utilizing the state-of-the-art methodologies.
