“…The results of the present study showed that the value of ST-segment duration ranged from 0.08±0.01 to 0.22±0.02 (second) with an average of 0.11±0.01 and 0.16±0.01 in sheep and goats, respectively. Our findings showed that ST-segment duration in goats was little different from that reported by Pogliani et al (2013) in Saanen goats (0.15±0.041) and was less than what was reported by Ahmed and Sanyal (2008) in Black Bengal goats (0.19±0.014). Also our findings showed that ST-segment duration in Kermani sheep was less than that reported by Ahmed and Sanyal (2008) in Garol sheep (0.13±0.010).…”

Also our findings showed that ST-segment duration in Kermani sheep was less than that reported by Ahmed and Sanyal (2008) in Garol sheep (0.13±0.010). It may be due to the breed variation, ECG lead system differences, heart rate, and size of body and heart during aging in sheep and goats.…”

The importance of obtaining normal values of ST-segment for specific breeds of animals besides the high variability of indices in small ruminant has been emphasized. The animals were assigned into 4 groups (G1-4), according to their age: G1<3 months, 3 months ≤G2< 1 year, 1 year≤G3<3 years, and G4 ≥ 3 years old. There were 34 animals in each study group. The animals were assigned to two comprising groups: sheep, goat, male and female. Also, the animals were divided into three groups according to their breed, including: Kermani sheep, Saanen and Cashmere (Raini) goats. The present study showed that sex, age and breed had no effect on ST-segment in sheep and goats and the obtained data can provide a good basis for judging the ST-segment length and morphology in difference sexes, breeds and age groups of sheep and goats.

“…This may have been due to a lack of coordinated atrial activity, so that P waves were not being formed, or it could be that P waves were present but were just not clear. The QRS complex was both monophasic and diphasic in different limb leads of Angora goats, as has been reported for other goat breeds (1,16,22). Smith and Sherman (22) reported that the T wave in goats was generally sharp and positive, especially in lead III; the exception was lead aVL, which showed a negative T wave.…”

“…Electrocardiographic examination is one of the methods most commonly used for detecting cardiac arrhythmias in sheep and goats (5); however, it has been reported that ECG parameters can vary among different breeds of goat (1,13,16,17). ECG studies in sheep and dogs have shown age-related variations (2,24).…”

“…For instance the goat has a small body size, reproduces easily, and costs little in monetary terms, which makes it preferable to other ruminants for biological research (23). Recently studies have been performed to investigate the normal ECG values in different goat breeds (1,13,16,17) and the effect of various chemicals on the goat heart (9,10,12,19).…”

Summary:Electrocardiography is a noninvasive and easily applied technique used in the determination of cardiac hypertrophy and dilatation, the classification of cardiac arrhythmias, and the diagnosis of conduction abnormalities. The aim of this study was to determine the normal electrocardiographic (ECG) values in Angora goats. A total of 30 healthy Angora goats of both sexes, ranging in age from 1 to 2 years, were used in the study. The 3 standard bipolar limb leads (I, II, III) and unipolar augmented limb leads (aVR, aVL, aVF) were recorded with the goats standing. The morphology and amplitude of P waves, QRS complexes, and T waves were analyzed in all leads. Cardiac rhythm, heart rate, and the durations of P, QRS and T waves, as well as the PR interval and QT interval, were calculated in the limb leads. The mean electrical axis for each individual was determined from the net amplitude of the QRS complex in leads I and III. Most of the animals had sinus rhythm. The mean heart rate was 108.71 ± 3.289 per minute and ranged from 75 to 143. The mean electrical axis was between -178° and +170°. In conclusion, the findings presented here may be useful to clinicians and researchers as reference values for the normal ECG of Angora goats.Keywords: Angora goat, configuration, electrocardiogram, wave. Ankara keçilerinde bazı elektrokardiyografik değerlerÖzet: Non-invaziv ve kolayca uygulanan elektrokardiyografi; kalpteki dilatasyon ve hipertrofilerin belirlenmesinde, kardiyak aritmilerin sınıflandırılmasında ve iletim bozukluklarının teşhisinde kullanılan bir tekniktir. Bu çalışmada Ankara keçilerine ait bazı elektrokardiyografik değerlerin ortaya konulması amaçlandı. Çalışmada her iki cinsiyetten, 1-2 yaş arası, toplam 30 tane sağlıklı Ankara keçisi kullanıldı. Hayvanlardan ayakta bipolar ekstremite derivasyonları (I, II, III) ve artırılmış unipolar ekstremite derivasyonlarının (aVR, aVL, aVF) kayıtları alındı. Tüm derivasyonlarda P dalgası, QRS kompleksi ve T dalgalarının morfolojileri ve amplitüdleri belirlendi. Ayrıca kalp ritmi ve dakika kalp atım sayısının yanısıra ekstremite derivasyonlarının tümünde P, QRS ve T dalgaları, PR aralığı ve QT aralığı süreleri hesaplandı. Her bir hayvan için I ve III. derivasyonlardaki net QRS kompleksi amplitüdünden ortalama elektriksel eksen belirlendi. Hayvanların çoğunda sinus ritmi bulundu. Dakika kalp atım sayısı ortalama 108,71±3,289, değişim aralığı ise 75-143 adet/dk olarak belirlendi. Ortalama elektriksel eksen -178° ile +170° arasında hesaplandı. Sonuç olarak, bu araştırmadan elde edilen bulguların Ankara keçilerine ait normal EKG değerleri ile ilgili bir referans olarak klinisyen ve araştırmacılara faydalı olacağı düşünülmektedir.

The most frequently used animal species in experimental cardiac electrophysiology are mice, rabbits, and dogs. Murine and human electrocardiograms (ECGs) show salient differences, including the occurrence of a pronounced J-wave and a less distinctive T-wave in the murine ECG. Mouse models can resemble human cardiac arrhythmias, although mice differ from human in cardiac electrophysiology. Thus, arrhythmia mechanisms in mice may differ from those in humans and should be transferred to the human situation with caution. Further relevant cardiovascular animal models are rabbits, dogs, and minipigs, as they show similarities of cardiac ion channel distribution with the human heart and are suitable to study ventricular repolarization or pro- and antiarrhythmic drug effects. ECG recordings in large animals like goats and horses are feasible. Both goats and horses are a suitable animal model to study atrial fibrillation (AF) mechanisms. Horses frequently show spontaneous AF due to their high vagal tone and large atria. The zebrafish has become an important animal model. Models in "exotic" animals such as kangaroos may be suitable for particular studies.
