Prevalence and Prognostic Significance of Long QT Interval in Patients With Acute Coronary Syndrome: Review of the Literature.

CONCLUSION:: The available evidence is contradictory and includes serious limitations in design and QT measurement and correction. Until accurate and reliable data are available, it is difficult to determine the additional clinical value and prognostic significance of long QT interval in patients with ACS beyond that in other patients. CLINICAL IMPLICATIONS:: Long QT interval is not uncommon among patients with ACS. Automated continuous QT interval monitoring is superior to manual QT interval measurement with the standard 10-second electrocardiogram. Optimum care for patients with ACS requires nurses to keep monitoring the QT interval several days after the initial event. PMID: 23839573 [PubMed - as supplied by publisher]

This study aims at evaluating chronic effects of different IMT intensities on cardiovascular control in amateur cyclists. A longitudinal, randomized, controlled, blind study was performed on 30 recreational male cyclists undergoing IMT for 11 weeks. Participants were randomly allocated into sham-trained group (SHAM, n=9), trained group at 60% of the maximal inspiratory pressure (MIP60, n=10), and trained group at critical inspiratory pressure (CIP, n=11). Electrocardiogram, finger arterial pressure and respiratory movements were recorded before (PRE) and after (POST) training at rest in supine position (REST) and during ac...

ConclusionAD, characterized by sympathovagal imbalance due to a reduced parasympathetic tone with high LF/HF ratio, could be responsible for the reduced myocardial vasodilatory response after CPT.

Authors: Tomichi Y, Kawano H, Mukaino A, Chiba A, Doi Y, Arakawa S, Ishimatsu T, Fukae S, Abiru N, Maemura K Abstract A 24-year-old Japanese man with type 2 diabetes mellitus and diabetic neuropathy was admitted to our ward to evaluate the cause of orthostatic intolerance. During a head-up tilt test, his heart rate increased from 105 to 155 beats/minute within 3 minutes, and chest discomfort began. He was diagnosed with postural orthostatic tachycardia syndrome (POTS), and orthostatic intolerance disappeared after β-blocker treatment. Scintigraphy using 123I-metaiodobenzylguanidine showed decreased cardiac upt...

ConclusionIn conclusion, cardiac sympathetic overdrive and decreased vagal control appear during CKD 4 and 5. The association with GFR is curvilinear. Diabetes mellitus was significantly associated with both cardiac and vascular autonomic neuropathy, as measured by heart rate variability and nocturnal blood pressure dipping, respectively. Knowing that arrhythmias, often due to sympathetic hyperactivity, are an important cause of sudden death in the dialysis population, this study contributes important knowledge on possible intervention thresholds.

Authors: Taranto-Montemurro L, Messineo L, Perger E, Salameh M, Pini L, Corda L, Ferliga M, Tantucci C Abstract Obstructive sleep apnea (OSA) and chronic obstructive pulmonary disease (COPD) coexist in 0.5-1% of the general population. Both OSA and COPD are associated with increased sympathetic nervous activity, and patients affected by both disorders have higher risk for increased morbidity and mortality as compared with patients with COPD or OSA alone. We tested the hypothesis that patients with COPD and OSA (Overlap syndrome) have higher sympathetic and lower parasympathetic modulation of heart rate variability ...

This study investigated the relationship between burnout and hemodynamic and autonomic functioning in both medical students (N=55) and premedical undergraduate students (N=77). Questionnaires screened for health related issues and assessed school burnout and negative affect symptomatology (anxiety and depression). Continuous beat-to-beat blood pressure (BP) through finger plethysmography and electrocardiogram (ECG) monitoring was conducted during conditions of baseline and cardiac stress induced via the cold pressor task to produce hemodynamic, heart rate variability, and blood pressure variability indices. Independent sam...

This study aims to noninvasively investigate the electrophysiological features in SDB patients with and without arterial HT. MethodsFifty‐three patients with SDB were classified into two groups: SDB group and SDB + HT group. Twenty subjects with arterial HT were enrolled as controls (HT group). To assess arrhythmogenic vulnerability, high‐resolution 24‐h ambulatory electrocardiograms were obtained for analyzing continuous late potential (LP), T‐wave amplitude variability (TAV), and heart rate variability (HRV). ResultsA higher incidence of positive LP was observed in the SDB + HT (85%) group than that observed in t...

The objective of this study was to explore the effect of 12 sessions of 0.5 Hz repetitive transcranial magnetic stimulation (rTMS) over dorsolateral prefrontal cortex (DLPFC) on autonomic activity in children with ASD. Electrocardiogram and skin conductance level (SCL) were recorded and analyzed during each session of rTMS. The measures of interest were time domain (i.e., R-R intervals, standard deviation of cardiac intervals, NN50-cardio-intervals>50 ms different from preceding interval) and frequency domain heart rate variability (HRV) indices [i.e., power of high frequency (HF) and low frequency (LF) compon...

Discussion: Although the VU-AMS version 5fs system detected anticipated hemodynamic and sympathetic nervous system changes to postural shift in participants (n = 10), the elimination of 64% (n = 18) of the sample because of scoring difficulties limits the use of this impedance cardiography device using standard scoring algorithms in persons with heart failure with reduced ejection fraction.
