Rest and exercise right and left ventricular function were compared using equilibrium gated radionuclide angiography in 19 normal sedentary control subjects (mean age 28 years, range 22 to 34) and 34 patients w
(which can be defined in hypertensive patients) can extend to the periodbeforethe appearance of fixed BP elevation. For example, echocardiographic indices ofdiastolic functionappear to become abnormal when measured BP is within the normal range in the offspring of parents with hypertension. Indeed, ...
The heart rate, QRS axis, QRS width, and QTc interval were normal. The mean QRS duration of PVC was 111 ± 31 ms. The morphology of PVC was observed as an LBBB pattern in 61 (56%) patients and OT-origin morphology in 54 (58.7%). 24-h Holter monitoring 24-h Holter monitoring...
Normal distribution of data was assessed using the Shapiro–Wilk test. Continuous variables were reported as mean ± standard deviation (SD) for normally distributed data, while non-normally distributed data were presented as median with interquartile range. Gender differences were evaluated using ...
In the present study, we showed that despite normal LVEF, RV function, in particular RV strains in HCM patients were significantly reduced, with a small reduction in RVEF although this was still within the normal range, for an age- and sex-matched controls. We also showed that LV strain pa...
We sought to investigate the association of prolonged ventricular repolarization with mild cognitive impairment (MCI) and the potential underlying neuropathological mechanisms in older adults. This cross-sectional study included 4328 dementia-free participants (age ≥ 65 years; 56.8% female) in ...
Regarding systolic function, we observed that EF remained within the normal range compared to the baseline both in smokers and controls with a mean value at 100 W of 69(2)% and 68.4(1.7)%, in smokers and controls respectively (p = ns). However, by analysing the LV systolic mechan...
In this study, we evaluated the activity of the cardiac autonomic nervous system by analyzing heart rate variability (HRV). The time-domain indices of HRV included the standard deviation of all normal sinus RR intervals (SDNN), the standard deviation of the average NN intervals for all 5-minut...
Nitrite infusion increased the ΔCO/ΔVo2 slope compared with placebo (+2.1 ± 2.2 ml/ml vs. +0.3 ± 1.7 ml/ml; p = 0.025) to a mean value that falls within the normal range for humans without heart failure (dotted line, Figure 3B), indicating an improvement in CO reserve relative...
It is defined as three or more consecutive ventricular beats occurring at a rate greater than 120 beats/minute (Fig. 16.27). The QRS morphology in VT is different from that in sinus rhythm, and the QRS duration is typically prolonged for age. ECG features that support this diagnosis include...
