Journal ArticleDOI
Mobile health technology evaluation: The mHealth evidence workshop
Santosh Kumar,Wendy Nilsen,Amy P. Abernethy,Audie A. Atienza,Kevin Patrick,Misha Pavel,William T. Riley,Albert O. Shar,Bonnie Spring,Donna Spruijt-Metz,Donald Hedeker,Vasant Honavar,Richard L. Kravitz,R. Craig Lefebvre,David C. Mohr,Susan A. Murphy,Charlene C. Quinn,Vladimir Shusterman,Dallas Swendeman +18 more
TL;DR: Current evaluation standards are described to describe current evaluation standards, discuss future possibilities, and set a grand goal for the emerging field of mHealth research.
Journal ArticleDOI
Upsurge in T-Wave Alternans and Nonalternating Repolarization Instability Precedes Spontaneous Initiation of Ventricular Tachyarrhythmias in Humans
TL;DR: The magnitude of repolarization instability, manifested by TWA and beat-to-beat oscillations of T-wave amplitudes at other frequencies, increased before the onset of VTA, which can facilitate timely detection of high-risk periods and may be useful for initiation of preventive treatments.
Journal ArticleDOI
Autonomic nervous system activity and the spontaneous initiation of ventricular tachycardia
Vladimir Shusterman,Benhur Aysin,Venkateshwar Gottipaty,Raul Weiss,Susan Brode,David Schwartzman,Kelley P. Anderson +6 more
TL;DR: Heart rate rose, whereas LFP, LFPnand LFP/HFP fell before the onset of VT, suggesting that alterations in autonomic activity contributed to arrhythmogenesis in this group of patients.
Journal ArticleDOI
Calcium-dependent arrhythmias in transgenic mice with heart failure.
Barry London,Linda C. Baker,Joon S. Lee,Vladimir Shusterman,Bum-Rak Choi,Toru Kubota,Charles F. McTiernan,Arthur M. Feldman,Guy Salama +8 more
TL;DR: Both action potential prolongation and abnormal Ca(2+) handling may contribute to the initiation of reentrant arrhythmias in this heart failure model by mechanisms distinct from enhanced dispersion of refractoriness or triggered activity.
Journal ArticleDOI
Atrial contractile dysfunction, fibrosis, and arrhythmias in a mouse model of cardiomyopathy secondary to cardiac-specific overexpression of tumor necrosis factor-α
Samir Saba,Andrzej M. Janczewski,Linda C. Baker,Vladimir Shusterman,Erdal Gursoy,Arthur M. Feldman,Guy Salama,Charles F. McTiernan,Barry London +8 more
TL;DR: Alarming abnormalities in action potential propagation and Ca(2+) handling contribute to the initiation of atrial arrhythmias in this mouse model of heart failure.
