Heart rate variability in sick sinus syndrome: does it have a diagnostic role?
2019
BACKGROUND: Hypothesis of our study was that the irregular rhythm of sick sinus syndrome (SSS) was characterized by an augmented HRV. Objective was to assess whether SSS patients had a typical HRV profile. METHODS: We screened all 1947 consecutive Holter ECGs performed in our Units of Vascular Medicine and Internal Medicine and Cardioangiology at the University of Palermo (Italy) from April 2010 to September 2014. Among these, we selected 30 patients with ECG criteria of SSS. They were compared to 30 patients without SSS matched for age, sex and comorbidities. RESULTS: The SSS group had a lower mean heart rate (HR) (P=0.003), and a longer mean NN max-min longer (P<0.0005) compared to con…
Feasibility of Ultra-Short-Term Analysis of Heart Rate and Systolic Arterial Pressure Variability at Rest and during Stress via Time-Domain and Entro…
2022
Heart Rate Variability (HRV) and Blood Pressure Variability (BPV) are widely employed tools for characterizing the complex behavior of cardiovascular dynamics. Usually, HRV and BPV analyses are carried out through short-term (ST) measurements, which exploit ~five-minute-long recordings. Recent research efforts are focused on reducing the time series length, assessing whether and to what extent Ultra-Short-Term (UST) analysis is capable of extracting information about cardiovascular variability from very short recordings. In this work, we compare ST and UST measures computed on electrocardiographic R-R intervals and systolic arterial pressure time series obtained at rest and during both post…
NEW TECHNOLOGIES AND INFORMATION MANAGEMENT IN THE HOSPITALITY INDUSTRY: ANALYSIS BETWEEN UPSCALE HOTELS IN ITALY AND CROATIA
2012
Uvođenje novih tehnologija i upravljanje informacijama neprestano pružaju priliku za diferencijaciju unutar uslužnog sektora, a posebice u hotelijerstvu. Napredak informacijsko komunikacijske tehnologije (ICT) dao je pozitivan doprinos ugostiteljstvu. Oblikovanje usluga i jačanje lojalnosti klijenata uvelike ovise o dostupnosti podataka o njima. Stoga je svrha ovog istraživanja ispitati primjenu novih tehnologija i upravljanja podacima u hotelijerstvu iz perspektive menadžera i korisnika usluga. Cilj rada je utvrditi postoje li razlike u njihovoj uporabi i percepciji između visokokategoriziranih hotela u Italiji i Hrvatskoj.
