“…Several studies have shown that the use of medicinal plants in chickens susceptible to pulmonary hypertension reduces the ratio of RV/TV (Ahmadipour et al, ; Ahmadipour, Hassanpour, Asadi, et al, ; Ahmadipour, Hassanpour, Asadi, et al, ). Electrocardiography is a noninvasive technique that is widely used to evaluate cardiac function during infectious and noninfectious diseases (Hassanpour, Zamani Moghadam, Teshfam, & Zarei, ). According to the results of this study, the proportion of RV/TV, RV/BW and TV/BW ratio as well as R, S and T wave amplitudes of electrocardiogram were declined as consumption 3 or 4 g/kg of S. securidaca in broiler diets.…”

This experiment was conducted to evaluate the effects of dietary Securigera securidaca seed powder on growth performance, haematological parameters, cardiac indices, electrocardiographic parameters and expression of catalase (CAT), endothelin 1 (ET-1) and inducible nitric oxide synthase (iNOS) genes in the lung in the broilers reared at high altitude (2,100 m above sea level). A total number of 200-day-old male broilers (Ross 308) were randomly assigned to five treatments including different levels of S. securidaca 0, 1, 2, 3 and 4 g/kg in a 42-day trial. The results of this experiment showed that the dietary inclusion of S. securidaca powder improvement in feed conversion ratio (p < 0.05). The dietary utilization of 2-4 g/kg S. securidaca significantly increased concentrations of nitric oxide (NO), although significantly lower serum concentrations of malondialdehyde (MDA) and significantly decrease T, R, S electrocardiogram waves compared with control group. Also, the dietary inclusion of 2-4 g/kg S. securidaca prevented right ventricular hypertrophy and increased the expression of iNOS and CAT genes in lung tissue of broilers. On the other hand, S. securidaca significantly suppressed the expression of ET-1 in lung tissue. Generally, the results of this study showed that the use of 3 g/kg of medicinal plant S. securidaca can be beneficial in prevention of pulmonary hypertension syndrome (PHS) in broiler chickens reared at high altitudes.

“…[13][14][15][16][17] As has been reported in mammals, 18 ECG parameters differ significantly among species of birds. 6,7,12,[18][19][20][21][22] These variations in ECG parameters among species support the need to determine specific ECG patterns and reference values for each species of exotic birds.…”

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.

“…The experiment was conducted in the experimental facility of Shahrekord University (2,100m altitude), Shahrekord, Iran, to evaluate the effect of different levels of hawthorn extract in the drinking water on the physiological responses of chickens affected with PHS and ascites. According to similar studies (Ahmadipour et al, 2015;Hassanpour et al, 2005;Hassanpour et al, 2008), hypobaric hypoxia was defined as reduced partial oxygen pressure that occurs at altitudes higher than1500m. Therefore, comparing to partial oxygen pressure of 21% at sea level, the partial oxygen pressure in the experimental site calculated as 15.75% and considered as an hypobaric hypoxia condition that may cause PHS and ascites (Julian 2000;Wideman et al, 2013).…”

Hawthorn has been traditionally used to improve blood circulation and medicating cardiac disorders as well as blood stasis and elimination of pulmonary hypertension. An experiment was conducted to evaluate the effect of different levels of hawthorn extract in the drinking water on cardiac indicators, serum antioxidant activity, growth and immunity of pulmonary hypertensive broilers reared at high altitude and prone to ascites. A total of 225 one-day-old unsexed broiler chicks (Ross308) were randomly assigned to 15 floor pens. A basal corn-soy based diet was formulated for all treatments. The treatments consisted of the addition of 0, 0.1, or 0.2 mL of hawthorn extract per liter of drinking water. Both levels of hawthorn flavonoid extract significantly (p<0.05) improved feed intake, body weight gain and FCR, and significantly (p<0.05) reduced abdominal fat, liver, and heart relative weights, as well as the number of birds affected with PHS compared with the controls. RV and TV were significantly (p<0.05) lower in hawthorn flavonoid extract fed birds than the controls in addition of significantly (p<0.05) lower TBARS but higher NO serum levels. In conclusion, hawthorn flavonoid extract may effectively be used as an herbal medicine to prevent pulmonary hypertension and cardiac disorders in chickens.
