The Washington University School of Medicine Heart Rate Variability Laboratory is one of the premier facilities for research Holter analysis in the world. Since our inception in 1995, we have stored approximately 15,000 files in our research archive. The laboratory specializes in exact characterization of continuous ECG signals, with special attention to accurate beat onset detection and ectopy identification.
We collaborate in academic, Department of Defense (DOD) and industry-sponsored studies, both large and small. All recordings are analyzed by research-trained Holter technicians and then carefully overread by the principal investigator, Dr. Phyllis K. Stein. The laboratory is capable of taking any continuous ECG and performing any desired HRV analysis of the signal.
