Background: There is a frequent association between renal insufficiency and patients with cardiovascular disease, suggesting a common pathogenic mechanism. The electrocardiogram (ECG) is a quick and cheap tool that can detect early cardiac abnormalities. The aim of this study was to quantitatively analyze ECG alterations in relation to renal function of a population of 65 years or older. Methods: A population sample of 1,536 patients aged 65 or older (45.4% male; mean age 75.6±6.0 years) from the judicial district of Toledo, Spain, who had undergone a general medical checkup including an ECG were included. In 996 patients (64.8%) renal function (plasma creatinine and estimated glomerular filtration rate) was assessed and the relationship between ECG alterations and renal function was subsequently evaluated. Results: Only 36% of the ECGs analyzed were considered normal. Significant correlations of heart rate, QRS complex duration, and the frontal plane QRS-T angle with reduced renal function were observed. Other ECG parameters such as voltage, QRS and T wave axes, and QTc interval showed no correlation with renal function. Conclusions: In patients aged 65 years or older with impaired renal function there was a relationship of renal function with certain ECG parameters, which may constitute early markers of renal and cardiac pathology and suggest a common pathogenic mechanism.

“…This study was approved by the ethical committee of the Faculty of Veterinary Medicine, Ghent University (Merelbeke, Belgium) (EC 2016/35) and animal care was according to their guidelines. Seven warmblood geldings aged 12.5 (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) years (median (range)) with height 163 cm (155-179 cm) at the withers and mass 548 kg (420-706 kg) were used. Four horses were owned by the Faculty of Veterinary Medicine, whereas three horses were donated for scientific research followed by euthanasia because of orthopedic problems.…”

“…The VCG provides additional insight that remains unexplored in the 12-lead ECG, such as the true QRS complex direction and amplitude in three dimensions and the spatial angle between the initial and maximum electrical axis of the QRS complex [ 14 , 15 ]. The VCG can be used to increase the power of statistical analyses by decreasing the number of independent variables because calculating the VCG from the 12-lead ECG offers a reduction in the number of independent leads from eight to three, with only minimal information loss [ 16 ].…”

In human cardiology, the anatomical origin of ventricular premature depolarizations (VPDs) is determined by the characteristics of a 12-lead electrocardiogram (ECG). Former studies in horses had contradictory results regarding the diagnostic value of the 12-lead ECG and vectorcardiography (VCG), which results were attributed to the different cardiac conduction system in this species. The objective of this study was to determine if the anatomical origin of pacing-induced VPDs could be differentiated in horses based upon VCG characteristics. A 12-lead ECG was recorded in seven horses under general anesthesia while right and left ventricular endomyocardial pacing was performed (800–1000 ms cycle length) at the apex, mid and high septum and mid and high free wall, and at the right ventricular outflow tract. Catheter positioning was guided by 3D electro-anatomical mapping and echocardiography. A median complex, obtained from four consecutive complexes, was calculated for each pacing location and sinus rhythm. The VCG was calculated from the 12-lead ECG-derived median complexes using custom-made algorithms and was used to determine the initial and maximum electrical axes of the QRS complex. An ANOVA for spherical data was used to test if VCGs between each paced location and between pacing and sinus rhythm were significantly (p < 0.05) different. The model included the radius, azimuth and elevation of each electrical axis. Pacing induced significantly different initial and maximum electrical axes between different locations and between pacing and sinus rhythm. The current results suggest that VCG is a useful technique to identify the anatomical origin of ventricular ectopy in horses.
