“…In this respect, there is compatibility between our results and those findings reported by many authors [16,17,[28][29][30] . On the other hand, Hassanpour et al found that the P waves were mainly positive in all leads in green peafowl [31] and in helmeted guinea fowl [32] . Machida and Aohagi [33] reported that the P waves are generally biphasic in lead I and III, and positive in lead II.…”

The aim of this study was to establish normal electrocardiographic values and patterns in pheasants (Phasianus colchicus). The electrocardiograms were recorded in 24 conscious pheasants from both genders. All electrocardiograms were standardized at 1 mV=20 mm , with a paper speed of 50 mm/sec. Morphological patterns of P, QRS and T deflections were evaluated in the six limb leads (I, II, III, aVR, aVL, aVF). The amplitude and duration of waves and intervals were determined by using lead II. A regular sinus rhythm was observed in all birds. There was no significant difference between male and female pheasants except for amplitudes of P and T waves and duration of T wave. In all leads P waves were mainly positive in both sexes except for lead aVR. The dominant waveforms of the QRS complexes were rS in lead II, III and aVF, and qR in lead aVR and aVL in both sexes. Generally, T waves were positive in lead I, II, III and aVF, and negative in aVL, aVF. The majority of birds showed a slightly elevated ST segment in lead II. Heart rates were 193.5±45.8 and 235.7±59.9 beats per minute and mean electrical axes were -91±10° and -92±18° in male and female birds, respectively. This study provides electrocardiographic data for pheasants, which can be used for clinical purposes.

Bu amaçla her iki cinsiyetten 24 adet uyanık sülünün elektrokardiyogramları 50 mm/sn hızda ve 20 mV/mm amplitüdte kaydedildi. Bipolar ve unipolar ekstremite derivasyonlarında (I, II, III, aVR, aVL, aVF) P, QRS ve T dalga morfolojileri değerlendirildi. Dalgaların süre, yükseklik ve aralıklarının hesaplanmasında derivasyon II kullanıldı. Çalışmada tüm kuşlarda düzenli sinüs ritmi izlendi. Erkek ve dişi sülünler arasında P ve T dalgalarının amplitüdü ve T dalgalarının süresi dışında önemli fark saptanmadı. P dalgası aVR dışında tüm derivasyonlarda her iki cinsiyette de pozitifti. Her iki cinsiyette de QRS kompleksi II, III ve aVF derivasyonlarında rS formunda, aVR ve aVL derivasyonlarında qR formunda gözlendi. T dalgası I, II, III ve aVF derivasyonlarında pozitif iken aVL ve aVF derivasyonlarında negatif olarak belirlendi. Derivasyon II'de ST segmentinde hafif bir yükselme saptandı. Kalp atım sayısı erkeklerde 193.5±45.8 atım/dk ve dişilerde 235.7±59.9 atım/dk olarak hesaplanırken, ortalama elektriksel eksen erkeklerde -91±10° ve dişilerde -92±18° olarak hesaplandı. Bu çalışma ile klinik amaçlar için kullanılabilecek sülünlere ait elektrokardiyografik veriler elde edilmiştir.

“…The sequence of the heart depolarization is followed by the right ventricular apex, right ventricular base, left ventricular base, and then the left ventricular apex. 4,5 The electrocardiogram (ECG) is a noninvasive, transthoracic graphic that shows electrical activity of the heart. In the clinical setting, an ECG is done subsequent to severe trauma, electrocution, or toxicoses, and in the workup of cardiac, metabolic, and/or electrolyte abnormalities.…”

“…6 Several studies have been published regarding ECGs in zoo birds. [5][6][7][8][9][10][11] The purpose of this study was to analyze the ECG tracings in unanesthetized Muscovy ducks (Cairina moschata) and to describe their normal ECG patterns and values. To our knowledge, the ECG parameters of the Muscovy duck have not been previously studied.…”

To describe normal electrocardiographic parameters in conscious Muscovy ducks (Cairina moschata), standard bipolar (I, II, and III) and augmented unipolar limb (aVR, aVL, and aVF) lead electrocardiograms were recorded in 10 clinically healthy birds. Wave forms were analyzed in all leads at 50 mm/s and at 10 mm= 1 mV to determine PR, QRS, ST, QT durations; the net QRS complex; and P and T amplitudes. The polarity of each waveform was tabulated in all leads. The mean electrical axis (MEA) for the frontal plane was calculated by using leads II and III. The mean (SEM) heart rate calculated from lead II was 146.6 - 6.8 beats/min. The P wave was predominantly positive in all leads. The dominant pattern of waveforms of the QRS complexes was rS in leads II, III, and aVF, whereas, in leads aVR, and aVL, the pattern was R. The T wave was positive in leads II, III, and aVF and was negative in leads aVR and aVL. The mean (SEM) of the heart MEA was -91.2 2 1.8. The electrocardiographic values and patterns tabulated in these clinically normal Muscovy ducks should provide a means of comparison to aid in the diagnosis of pathologic abnormalities in this species.

It has been hypothesized that Helicobacter pylori (Hp) infection may contribute to reduced stature, risk of hypertension or obesity. The aim was to evaluate body indices in Hp positive and negative persons. A total of 2436 subjects (4-100 years old) were tested for Hp status by 13 C-urea breath test. Data on height and weight were collected for 84%, and blood pressure for 80% of the study subjects. The prevalence of Hp infection was 41.6%. The odds ratio for a 10-year increase in age was 1.21 (95% CI 1.17-1.25, p-value <0.001). Statistically significant negative association of Hp positivity with body height was most pronounced in the younger age groups, while a positive association of Hp positivity with body mass index was only seen in those aged 15+ years. There was a negative effect of Hp positivity on systolic and diastolic blood pressure in subjects below 25 and a relatively strong positive effect on blood pressure in subjects over 65 years. Residual confounding by social characteristics as a possible explanation for the associations of Hp positivity with height and blood pressure cannot be excluded. Unmeasured factors related to social and family environment may cause the apparent association between Hp positivity and children's growth and blood pressure.
