“…9 The ECG can also be part of the clinical assessment of birds in zoological collections in which cardiac, metabolic, and/or electrolyte abnormalities can result from trauma, electrocution, and poisoning. Until now, however, little information on the ECG parameters of unanesthetized avian species kept in zoological collections has been available, [10][11][12][13][14] although, in some cases, ECG data have been obtained from sedated or anesthetized birds. 10,12 The purpose of this study was to analyze the feasibility of obtaining ECG tracings in conscious helmeted guinea fowl (Numida meleagris) and to describe the normal ECG patterns and values for this species.…”

The goal of this study was to describe normal electrocardiographic (ECG) patterns and values in conscious helmeted guinea fowl (Numida meleagris). Using 8 clinically healthy birds, 4 males and 4 females, standard bipolar and augmented unipolar limb lead ECGs were recorded. 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 wave form was tabulated in all leads. The mean electrical axis (MEA) for the frontal plane was calculated by using leads II and III. The mean (SD) heart rate calculated from the lead II was 338.4 +/- 19.0 beats/min. The P wave was predominantly positive in all leads. The dominant pattern of wave forms of the QRS complexes was RS in leads II, III, and aVF; R in lead I; QR in lead aVR; and qR in lead aVL. The T wave was predominantly positive in leads I, II, III, and aVF. The mean (SD) of the heart MEA was -60.2 degrees +/- 24.0 degrees. The ECG values and patterns tabulated in these clinically normal helmeted guinea fowl should provide a means of comparison to aid in the diagnosis of pathologic abnormalities in this species.

The aim of this study was to describe normal electrocardiogram (ECG) patterns and values in unanesthetized green peafowl (Pavo muticus). The standard bipolar and augmented unipolar limb leads ECGs were recorded in the birds. The waveforms were analyzed in all leads at 50 mm/sec and at 10 mm = 1 mV to determine P, PR (segment and interval), QRS, ST, QT durations, P, net QRS complex and T amplitudes. The polarity of each waveform was tabulated in all leads. The mean electrical axis (MEA) for the frontal plane was calculated using leads II and III. The mean heart rates were calculated from lead II that was 257.5 ± 5.33 beats/min. The P wave was dominantly positive in all leads. The dominant pattern of waveforms of the QRS complexes were QS in leads II, III, and aVF. In leads I, aVR and aVL, the R pattern was dominant. The T wave was almost positive in leads I, II, and aVF. The average value of the heart MEA was -96.75 ± 3.31°. Description of normal ECG parameters will facilitate a better realizing of ECG changes of unhealthy green peafowls.

“…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.
