The Evolution Of Nuclear Cardiology Takes Us Back To The Beginning To Develop Today's 'New Standard Of Care' For Cardiac Imaging: How Quantifying Regional Radioactive Counts At Five And 60 Minutes Post-Stress Unmasks Hidden Ischemia
Autor: Gordon M. Harrington, Kayla Avery, Richard M. Fleming, Scott Jay, Sridevi Challapalli, Jim Green, Riaz Baqir
Publikováno v: Methodist DeBakey Cardiovascular Journal. 5:42-48
The history and evolution of nuclear cardiology in relation to cardiac imaging is discussed. A description of the new standard of care for cardiac imaging and how it contributes to clinical cardiology is highlighted.

Relationship of Heart Rate Variability to Parasympathetic Effect
Autor: Alan H. Kadish, Sridevi Challapalli, Michele Parker, Roderick Tung, Jeffrey J. Goldberger
Publikováno v: Circulation. 103:1977-1983
Background —Baroreflex-mediated parasympathetic stimulation has variable effects on heart rate variability (HRV). We postulated that a quadratic function would describe the relationship between HRV and parasympathetic effect better than a linear fu

Differential Effects of Parasympathetic Blockade and Parasympathetic Withdrawal on Heart Rate Variability
Autor: Alan H. Kadish, Sridevi Challapalli, Jeefrey J. Goldberger, George Horvath
Publikováno v: Journal of Cardiovascular Electrophysiology. 10:1192-1199
Parasympathetic Withdrawal and Blockade Effects on HRV. introduction: Low heart rate variability (HRV) has been shown to have important prognostic significance in multiple settings. Although this is believed to reflect reduced parasympathetic tone, t

Twelve-Lead QT Dispersion Is Smaller In Women Than In Men
Autor: George Horvath, Rajeswari Lingamneni, Alan H. Kadish, Sridevi Challapalli, Michele Parker, Jeffrey J. Goldberger
Publikováno v: Annals of Noninvasive Electrocardiology. 3:25-31
Background Although gender differences in the corrected QT interval (QTc) have been described, gender differences in QT dispersion (QTd) have not been carefully evaluated. This study was designed to measure QTd in 22 young healthy women and in 20 hea

Uncertainty principle of signal-averaged electrocardiography
Autor: Sridevi Challapalli, Alan H. Kadish, Shmuel Inbar, David A. Johnson, Jeffrey J. Goldberger, Mirza W. Ahmed, Michael Waligora
Publikováno v: Circulation. 101(25)
Background —Signal-averaged ECG (SAECG) reproducibility is reported to have a component that is independent of residual noise. Methods and Results —In group 1, multiple paired SAECGs were obtained to noise levels of 0.3±0.1 and 0.5±0.2 μV. For

Congestive heart failure due to reversible cardiomyopathy in patients with hyperthyroidism
Autor: Guillermo E. Umpierrez, Cam Patterson, Sridevi Challapalli
Publikováno v: The American journal of the medical sciences. 310(3)
The authors describe the clinical characteristics and response to therapy of seven patients with hyperthyroidism, dilated cardiomyopathy, and low-output cardiac failure. All patients (4 women and 3 men, age 47 +/- 4 years, mean +/- standard error of
