A Survey on Electrocardiographic Parameters in Broiler Chickens Following the Intracerebroventricular Injection of Melatonin

Objective- The pineal gland and its principal hormone melatonin play an important role in the circadian organization in birds. However, little is known about the role of melatonin in cardiac activity of broiler chicken. The aim of this study was to assess the impact of intracerebroventricular injection of melatonin in electrocardiographic parameters, heart rate and mean electri...

Effects of intracerebroventricular injection of histamine and H1, H2 receptor antagonists on electrocardiographic parameters in broiler chickens

The aim of this study was to assess the effects of exogenous histamine and H1 and H2 central receptorson electrocardiographic (ECG) parameters, heart rate and mean electrical axis in broiler chickens. For thispurpose, Ross broiler chickens (750-800 g weight) received intracerebroventricularly (ICV) histamine.Moreover, to determine the receptors involved in histamine-induced alterations in ECG c...

Electrocardiographic parameters of Markhoz goat using base apex lead and six standard limb leads

Electrocardiographic study of 50 healthy Markhoz goats ranging from less than 1 to more than 3 years inage was carried out. The heart rate varied from 99 to 123 beats/min with a mean of 110 beats/min. There wasa significant difference between the heart rate of goats in 3 age groups (PT waves and QT interval in base apex lead, QRS wave in lead I, P-R and PQ interval in aVF lead were higherand du...

Seasonal and circadian variations of hemodynamic and electrocardiographic parameters in telemetered beagle dogs

The Effect of Iron Replacement Therapy on Electrocardiographic Consequences in Pediatric Patients

Background Sudden cardiac death is an important problem, because the patients have no opportunity to receive medical service. Recently some electrocardiogram (ECG) parameters are used for predicting arrhythmias, including P wave duration for predicting atrial arrhythmias and corrected QT and T wave peak to end interval (Tp-e), for predicting ventricular arrhythmi...
