“…5,7,12,[14][15][16] Some of the other values obtained with the sECG such as P wave duration, QRS duration, PR interval, and QT interval were either very similar to or slightly different from those reported in Roe deer and domestic ruminant species. 7,8,17 The mean ± SD T wave amplitude recorded in our Sika deer was 0.58 ± 0.40 mV, which was nearly identical to reported values for Roe deer (0.59 ± 0.33 mV) in the base-apex measurement performed in that study, 7 but slightly higher than the amplitude obtained with the lead II standard bipolar and augmented unipolar limb leads in the same Roe deer (0.20 ± 0.79 mV) and in geriatric cattle 8 (0.34 ± 0.01 mV) and Chios sheep 17 (0.12 ± 0.050 mV). Such differences when comparing base-apex ECG to the standard bipolar limb leads in both deer and Chios sheep should be taken into consideration when measuring and comparing cardiac electrical activity in ruminants.…”

OBJECTIVE To describe qualitative and quantitative cardiothoracic values in geriatric Sika deer (Cervus nippon) using digital radiography, 6-lead ECG (sECG), and smartphone-based ECG (aECG). ANIMALS 10 healthy geriatric Sika deer (9 females and 1 male). PROCEDURES Deer were chemically immobilized, thoracic radiographs were obtained, and inhalant anesthesia was initiated. An sECG and aECG were simultaneously recorded for each animal using the same ECG specifications. Results were compared between devices. RESULTS Radiographically, no deer had any cardiopulmonary abnormalities. Median (range) values for the most important cardiac measurements were 170 (153–193) mm for cardiac height, 135 (122–146) mm for cardiac width, 9 (8–9) for vertebral heart score, and 99 (69–124) mm for cardiosternal contact. All deer had a normal sinus rhythm with no pathological arrhythmias noted. A significant difference between sECG and aECG was identified for minimum heart rate (49 vs 51 beats/min, respectively), P wave duration (0.05 vs 0.03 seconds), P wave amplitude (0.28 vs 0.10 mV), PR interval (0.15 vs 0.12 seconds), and QT interval (0.39 vs 0.30 seconds). CLINICAL RELEVANCE Thoracic radiographs were suitable to evaluate basic cardiothoracic morphology in Sika deer. The aECG was useful for assessing heart rate and rhythm but, compared with sECG, proved no substitute for evaluating duration and amplitude of ECG waveforms.

“…It was stated that the ECG data could be altered according to factors that would change the heart pulse counts per minutes such as age, gender, stress, drug administration etc. (1,10,22,26,28). Different studies reported in their respective studies that the durations of P and T-waves, QRS complex, PR, QT, and ST intervals, the amplitudes of P and T-waves decrease when the heart pulse counts per minute increase (10,22,28).…”

Different studies reported in their respective studies that the durations of P and T-waves, QRS complex, PR, QT, and ST intervals, the amplitudes of P and T-waves decrease when the heart pulse counts per minute increase (10,22,28). Similarly in our study, the groups of higher heart pulse counts per minutes were provided with shorter durations for P and T-waves, QRS complex, PR and QT intervals, and with lower amplitude for P-wave.…”

The objective of the study was to investigate the stress effects induced by transportation in blood parameters and in electrocardiography data in Kangal Akkaraman sheep breed. Clinically healthy 36 Kangal Akkaraman sheep were used in the study. Electrocardiography data from the sheep were obtained by holder device during the resting period, and during 30 minute and 120 minute transportation periods. Blood parameters were determined from serum samples obtained during resting period, and after 30 minute and 120 minute transportations. Significant differences were obtained in the durations both PR to QT interval and P-wave, in the amplitude of P-wave, in heart pulse count per minute, and serum glucose levels in groups of resting and 30 min transportation, and resting and 120 transportation, and 30 min transportation and 120 min transportation. Significant differences were obtained for durations of both the QRS complex and T-wave in groups of resting and 30 min transportation, and of 30 min transportation and 120 min transportation. Significant differences were obtained for serum total protein, albumin, and creatinine levels in groups of resting and 120 min transportation, and 30 min transportation and 120 min transportation. No significant difference was obtained for serum blood urea nitrogen levels between study groups. This study is the first in literature where the effects of transportation induced stress in electrocardiography data and blood parameters in Kangal Akkaraman breed sheep were investigated.

“…The predominant negative correlation was noticed between the PR interval and the heart rate was noticed while aging. Chalmeh et al [4] reported the electrocardiography parameters in Chios breed as mean amplitude of P wave, QRS complex and T wave was in 0.052±0.016, 0.054±0.012 and 0.110±0.057 mV respectively in Chios breed lambs and it was 0.055±0.010, 0.059±0.018and 0.122±0.050 mV respectively. These findings were within range of present study.…”

“…Nellore cross-breed sheep is one of the common adapted breeds in the YSR District of Andhra Pradesh and it is the source for meat production which contributes significant economy to the formers ( Figure 1). There are several kinds of literatures on electrocardiographic studies in different animals including in ruminants, but there is no previous study regarding the normal ECG parameters at different age groups in the Nellore cross -breed sheep [3,4]. The current study was done to provide ECG values and to evaluate the effects of age on these parameters in this breed.…”

Aim: Present study was aimed to record the electrocardiography indices in different age groups of clinically healthy Nellore cross-breed sheep.Background: Normal electrocardiographic studies of different species of animals help in detection of cardiac abnormalities and helpful while monitoring the vital parameters during the diseased conditions, treatment trails and operative procedures. Variations in the parameters were recorded in small ruminants based on the breed. Information pertaining to the electrocardiographic findings of Nellore cross-breed sheep was not documented. Methodology:The present study was conducted at College of Veterinary Science, Proddatur, YSR Kadapa District of Andhra Pradesh, India from 2013 to 2016. Apparently, healthy local Nellore cross-breed of sheep were categorized into five groups based on their age and in each group twenty sheep were included. The animals were examined prior to ECG recording and were proved to be clinically healthy. The electrocardiography was recorded on a bipolar base apex lead system. Duration and amplitude of the P, QRS complex and T wave and the PR, QT intervals and heart rate were measured and averaged from successive beats in lead I. Results:Heart rate was 73.2±1.62 in adults and it was 115.8±2.76 in kids. The mean amplitude of P wave was 0.169±0.005 mV in lambs and 0.177±0.005 mV in the adult group. Mean duration of P wave, QRS complex and T wave was 0.044±0.003 sec, 0.066±0.003 sec, 0.103±0.003 sec in adult group and it was 0.041±0.006 sec, 0.063±0.003 sec and 0.104±0.004 sec in kids. Conclusion:No significant difference was found in P wave amplitude, duration of P wave, QRS complex and T wave. The heart rate, an amplitude of ECG waves including QRS complex, T wave and duration of P-R, Q-T and R-R intervals showed the significant difference between the age groups. Heart rate was gradually decreased while aging and the negative correlation between age of the sheep and heart rate was noticed. This study provides information on the cardiac rhythm, heart rate, duration, and amplitude of ECG deflections in one of the common sheep breed in the YSR District of Andhra Pradesh.Keywords: Sheep; Electrocardiography; Heart rate; Nellore brown Materials and MethodsThe present study was conducted at Department of Veterinary Clinical Complex, College of Veterinary Science, Proddatur, Andhra Pradesh from 2013 to 2016. Apparently healthy local cross-breed of sheep (Nellore) were categorized into five groups based on their age and in each group twenty sheep were included. Sheep were categorized into Group-I (below six months), Group-II (six months to one year), Group-III (one year to two years), Group-IV (two years to three years) and Group-V (above three years). The animals were examined prior to ECG recording and were proved to be clinically healthy. The electrocardiography was recorded on a bipolar base apex lead according to the standard and previous studies [5]. Electrocardiography recording was done in a quiet standing position by using the alligator type e...
