“…Tilley et al (2008), a onda P é o resultado da despolarização atrial, sendo que a amplitude refere-se à despolarização atrial direita, enquanto a duração refere-se à despolarização atrial esquerda. Desta forma, a interpretação para casos de aumento atrial direito deve ser feita de forma criteriosa, visto que diversos parâmetros eletrocardiográficos são passíveis de alterações em relação às raças (Fernandes et al, 2004;Diniz et al, 2008;Melchert et al, 2012) e às técnicas eletrocardiográficas empregadas (Camacho et al, 2010;Gava et al, 2011;Oliveira et al, 2013 A análise dos traçados eletrocardiográficos revelou que em 7,32% dos mesmos a onda P apresentou-se bifásica para os dois métodos de ECG conforme demonstra a Fig. 2.…”

RESUMOA eletrocardiografia computadorizada é mais precisa e prática quando comparada à convencional e por essa razão vem ganhando espaço na rotina clínica. No entanto os valores de referência devem diferir para os dois métodos. O objetivo desse trabalho foi analisar e comparar o exame eletrocardiográfico computadorizado com o exame obtido pelo método convencional em equinos. O estudo demonstrou diferenças na amplitude da onda P (P<0,0001) com valor médio de 0,21 mV para o método convencional e 0,17 mV para o computadorizado; duração do intervalo PR (p=0,0005), tendo o valor médio de 260,49 ms para o método convencional e 242,37 ms para o informatizado e duração do complexo QRS (p=0,0003), sendo a média de valores para o método convencional de 75,61ms e 84,83 ms para o computadorizado. Essas diferenças devem ser levadas em consideração com o intuito de evitar equívocos na interpretação da eletrocardiografia na espécie equina.Palavras-chave: cavalo, eletrocardiografia digital, impulso elétrico cardíaco ABSTRACT Computerized electrocardiography has been gaining space in clinic routines

“…Não foram observadas diferenças na amplitude da onda P, R e T as quais permaneceram dentro dos valores aceitos para a espécie [19,28], bem como, não foi observado desnível de segmento ST, o qual poderia indicar hipóxia ou isquemia do miocárdio [30]. Aumento da onda T sugestivos de hipóxia do miocárdio, já foram descritos após uma hora de infusão de propofol e cetamina em altas doses (0,4 mg/kg/min e 200 µg/kg/min) [3].…”

Background: General anesthetics and sedatives are commonly used for long-term sedation in veterinary medicine; however, they can lead to cardiac suppression. Cardiac troponin I is a biomarker used to detect myocardial pathology, monitor treatment, and assess outcomes in veterinary patients. The aim of this study was to evaluate the serum concentration of troponin I (cTnI), the electrocardiographic (ECG) tracing, and the ventricular stroke work index in dogs undergoing two long-term sedation protocols over 24 h. Materials, Methods & Results: Twelve healthy mongrel dogs with an average weight of 13.2 ± 2.3 Kg were admitted for this study. Twenty-four h before the experiment began (M-24), venous blood samples were collected for chemiluminescent cTnI evaluation and ECG data were obtained, specifically heart rate (HR); P, PR, QRS and T wave duration; P, R, T wave amplitude; and ST segment depression. On the day of the experiment, the animals were anaesthetized with propofol and isoflurane, and instrumented. After instrumentation, right and left ventricular stroke work index (RVSWI and LVSWI respectively) and intrapulmonary shunt (Qs/Qt) were performed as baseline parameters. The isoflurane was then discontinued and the animals randomly allocated to two groups (n = 6 each): Midazolam and fentanyl group (GMF), in which the animals received a bolus and continuous rate infusion (CRI) of midazolam (0.5 mg/kg and 0.5 mg/kg/h) and fentanyl (5 µg/kg and 10 µg/kg/h) or ketamine and morphine group (GKM), in which the animals received a bolus and CRI of ketamine (1 mg/kg and 0.6 mg/kg/h) and morphine (0.5 mg/kg and 0.26 mg/kg/h). Both groups also received propofol as a bolus and CRI (3 mg/kg and 0.3 mg/ kg/min) over 24 h. The ECG and cTnI parameters were evaluated at 6, 12, and 24 h during CRI (M6, M12, and M24) and 12 and 24 h after the end of infusion (T12 and T24). The hemodynamic parameters RVSWI, LVSWI, and Qs/Qt were evaluated every 2 h until the end of CRI. There was a non-significant increase in cTnI from M6 in both groups; however, a significant increase was only observed in GMF between M-24 and T12. During sedation, HR decreased an average of 46% in GKM and 51% in GMF compared to M-24. The QT interval (milliseconds) increased in both groups after CRI started, returning to baseline values at T24. There were no differences in P, QRS, and T wave amplitude or ST segment depression in either group. Discussion: The serum concentration of cTnI increased in GMF at T12, more probably due to hemodynamic changes during sedation rather than myocardial lesions, since the increase was relatively mild. A greater hemodynamic change was observed in GMF, with a greater increase in RVSWI compared to baseline than GKM, which may reflect an increase in cardiac effort and possibly cTnI release; however, in both groups, the cTnI values remained within the acceptable values for the species. Bradycardia was reported during long-term sedation, which may be due to the synergism between opioids as a result of vagal stimulation, central s...

“…Thus, further research in the area is necessary (KOETHER et al, 2016). Electrocardiography is a non-invasive exam (MENDES NETTO, 2014;OLIVEIRA et al, 2013) that promote the graphical visualization of linear segments showing the results of depolarization and repolarization of cardiac cells (NUNES et al, 2014). According to Oliveira et al (2008) the best results in relation to the capture of electrocardiographic tracing in cattle is the use of electrodes on the four limbs, with a similar indication for sheep.…”

“…The use of computerized electrocardiography has become frequent in veterinary medicine due to its handling, sensitivity in capturing traces and practicality when compared to conventional devices (PELTER; ADAMS; DREW, 1996;OLIVEIRA et al, 2013). According to Pereira Neto et al (2006) the test can be used for different diagnostic purposes, such as preoperative evaluation, electrocardiographic monitoring, recognition of arrhythmias, suggesting cardiac remodeling or the presence of chest effusions.…”

Article historyComputerized electrocardiography is a method widely used in veterinary medicine in several species and currently, with the availability of several devices in the market. In sheep, studies have shown variations in electrocardiographic values according to race, age, and methods of capture, but the values obtained in different computerized devices have not been compared. Thus, the present study sought to determine and compare the values of electrocardiographic variables between two computerized devices in healthy sheep. Fifty sheep (n = 50), Suffolk breed, female, launched, adult, nonpregnant, with average age and weight of two years and 50kg, respectively, were studied properly selected and clinically fit. The electrocardiographic tracings were obtained in two computerized electrocardiography devices (Apparatus A and B) individually and subsequently, with subsequent recording and interpretation of the tracings. The results showed a predominance of sinus rhythm in 78% (n = 39) and 22% (n = 11) with sinus arrhythmia in both devices. Significant differences among the devices (p <0.05) were identified in the duration variables (ms), such as P wave, P-R interval and segment, QRS complex, Q-T interval, S-T segment and T wave; and in the P-wave and R-wave amplitudes (mV). However, the values obtained were within the normal ranges recommended for the species, regardless of the capture method used. Thus, it is possible to conclude the presence of different values among the computerized electrocardiographs, suggesting variations in the tracking uptake sensitivity among the devices in released Suffolk sheep.
