“…In this study, P wave durations were measured over 11 leads, whilst in the study by Michlik et al, only 9 leads were used [ 40 ]. Previous studies in animals have used either six or nine leads to calculate the P wave indices [ 37 , 38 , 39 ]. However, it has been reported that the use of adjacent leads with shared vectorial orientation may provide greater sensitivity for distinguishing inhomogeneity of atrial activation [ 46 ], and it has been suggested that ECGs with ≤nine leads should be excluded from the analysis [ 9 , 45 , 46 ].…”

“…Few studies have reported the use of P wave indices in veterinary medicine [ 37 , 38 , 39 , 40 , 41 , 42 ]. In dogs, Pd has been shown to be significantly increased in those with chronic valvular disease and disturbances of supraventricular conduction [ 38 , 42 ] and was also found to be a useful predictor of arrhythmia recurrence following electrical cardioversion of AF [ 39 ]. In horses, only one study has been performed to determine the values of Pd in healthy Silesian and Polish primitive horses [ 40 ].…”

P wave indices are used as non-invasive electrocardiographic markers of atrial remodelling in humans. Few studies have investigated their use in animals. The aim of this study was to measure P wave duration and P wave dispersion (Pd) in healthy standardbred horses and investigate variables that might influence these measurements. A 12-lead electrocardiogram was recorded at rest and P wave indices were calculated in 53 horses. A general linear model was used to investigate the main effects: age, bodyweight, sex, resting heart rate, presence of a murmur, exercise status and the number of years raced. There were significant associations with exercise status for both the maximum P wave duration and Pd, with both values being increased in strenuously exercising versus non-active horses. Furthermore, a significant moderate positive correlation was identified between the duration of exercise (number of years raced) and both Pmax and Pd. No other significant associations were identified. These findings are similar to those reported in elite human athletes versus sedentary individuals. The increases in these P wave indices most likely occur due to prolongation and heterogeneity in atrial conduction time, which are associated with structural and electrical remodelling, and may explain the increased risk of atrial fibrillation in athletic horses.

“…[5] A study in dogs found higher Pd values predictive of PAF recurrence after cardioversion. [6] High Pd values have also been found in patients with metabolic syndrome and HT risk. [7] Atrial dilation and atrial interstitial fi brosis have been recognized in atrial remodeling; these changes involve the renin-angiotensin system, which is already known to be part of the pathophysiology of hypertension, through the profi brotic effect of angiotensin II.…”

This study is part of the Development Center Community Outreach project for diagnosis and management of hypertension in children (PROCDEC II) in Spain and Cuba, which began in 2000; the Cuban segment includes 5025 children aged 8-11 years from 43 urban primary schools in the municipality of Santa Clara in Villa Clara Province and involves a multidisciplinary research group of pediatricians, cardiologists, pediatric cardiologists, endocrinologists, clinical laboratory specialists, psychologists, statisticians and computer scientists. [15] A detailed clinical history was taken of all children and pertinent testing performed (two-dimensional abdominal and renal ultrasound, renal artery Doppler ultrasound, thyroid hormones, echocardiogram to rule out coarctation of the aorta, vanilmandelic acid, fundoscopic exam, creatinine, proteinuria, albuminuria and microalbuminuria) to diagnose essential and secondary hypertension. Participants were also assessed for other comorbidities (diabetes; hematologic, renal and adrenal diseases; hypertrophic cardiomyopathy) and for pubertal development (Tanner stage). [16] Type of study and sample A cross-sectional study was conducted from September 2009 through June 2011, using cluster sampling and randomly selecting the schools involved, with

Canine visceral leishmaniasis is a protozoan disease affecting most vital organs and also causing myocardial and/or renal damage. P-wave dispersion, a newly used non-invasive ECG indicator, is used to follow atrial arrhythmias, atrial fibrillation, valvular disease in both human and veterinary medicine. The purpose of this study involving Canine Visceral Leishmaniasis (CVL)-infected dogs in stage III and IV was to verify whether the P-wave dispersion was related to the renal failure. For this purpose, a total of 17 dogs of different ages, both sexes, comprising eleven animals with CVL (at stage III and IV) diagnosed using a rapid ELISA (enzyme-linked immunosorbent assay) test and serological IFAT (immunofluorescence.antibody titres) and six healthy dogs used as controls were enrolled. Significant differences between the P-wave dispersion (regarding the mean values) of the control, stage III and IV-infected groups (P = 0.003) were detected as follows: 21.8 ± 0.5, 20.6 ± 1.2 and 25.0 ± 0.4 ms, respectively. The P-wave dispersion value was moderately longer in the stage IV-infected group compared with the control one (P = 0.022), however, the aforementioned relationship was determined as significant between the stage IV and III-infected groups (P = 0.003). Regarding all of the biomarkers of the renal function monitored within this study, there were differences between the control and stage IV-infected group for the creatinine (P = 0.002), the control and stage IV-infected group for the urine protein/creatinine ratio (P < 0.001), and the stage III and stage IV-infected groups for the urine protein/creatinine ratio (P < 0.001). In conclusion, an increased P-wave dispersion was not associated with renal failure. It might be related to the limitation of our study including small sample sizes in the groups. Therefore, the cardiac indicators were not analysed. For more accurate results, it is desirable to perform further studies including a larger sample size along with an investigation of the cardiac and renal indicators.
