“…The reptilian heart can be classified as crocodilian and non-crocodilian. In the non-crocodilian heart, the ventricles are not physically divided and the pulmonary and systemic blood flow are separated and regulated by functional plasticity, divided by incomplete muscular ridges (White, 1976;Farrell et al, 1998;Schilliger, 2012).…”

“…Cardiac diseases are difficult to diagnose in turtles and tortoises, and most are not discovered until necropsy (Hnizdo and Pantchev, 2011). Direct auscultation is not possible in chelonians, but Doppler probes help determine the pulse frequency (Murray, 2006b;Schilliger, 2012).…”

“…Electrocardiography (ECG) could be helpful in diagnosing cardiac disease in the reptile patient (Murray, 2006b). Standardised ECG techniques according to Einthoven have been used in the past (Murray, 2006b;Schilliger, 2012). Unfortunately, standard ECG parameters are not established for many species (Schilliger, 2012).…”

Unfortunately, standard ECG parameters are not established for many species (Schilliger, 2012). Interpretation is difficult due to the limited amount of reference material and the limited degree of sensitivity of the equipment available (Kik and Mitchell, 2005).…”

The lack of knowledge on how to perform species-specific electrocardiographic (ECG) measurements in chelonians makes ECG evaluations difficult. The aim of this study was to establish non-invasive methods for ECG sample collection in different species of non-anaesthetised chelonians, focusing on adhesive and clamp electrodes. A total of 72 turtles and tortoises from 20 species and various sizes were used for the study. Body weight ranged from 32 g to 65 kg. From the aspect of specimen fixation, dorsal recumbency proved to be the most useful. Both adhesive and clamp electrodes yielded results when applied to the plastron and skin folds. Pre-emptive results suggest an indirect correlation with plastron thickness, the presence of a hinge, habitat and measurable ECG wave amplitude. ECG wave recordings are more likely in aquatic chelonians and species with a hinge. With size the plastron also thickens, making wave detection impossible. ECG waves were detected in 41 of the 72 specimens, complete PQRST complexes in 19 animals, with the rest showing absent P waves in all leads. ECG amplitudes were below 1 mV, with an average of 0.15 mV R wave amplitude.

Pericardial effusion in a central bearded dragon (Pogona vitticeps), with a technique for pericardiocentesis

A 10‐year‐old central bearded dragon (Pogona vitticeps) presented with dyspnoea, tachypnoea, lethargy, pale mucous membranes, excessive oral mucus and exercise intolerance. Echocardiography demonstrated a marked pericardial effusion. A pericardiocentesis was performed under general anaesthesia, demonstrating cytology consistent with a presumptive diagnosis of a proteinaceous effusion secondary to atherosclerosis. Nonspecific abnormalities were diagnosed on haematology and biochemistry, including a heterophilia, bacteraemia, hypoproteinaemia, elevated aspartate aminotransferase and a hyperphosphatemia. Full‐body radiographs demonstrated an enlarged cardiac silhouette with no other abnormalities detected. Echocardiography demonstrated a marked pericardial effusion. A pericardiocentesis was performed under general anaesthesia demonstrating cytology consistent with a non‐inflammatory cause. The patient was started on furosemide, pimobendan and benazepril. After an initial improvement, the patient declined and the owner elected euthanasia on humane grounds after 4 weeks. Pericardial effusion is becoming better recognised in bearded dragons; however, there is little to no literature available describing antemortem diagnostic protocols, treatments and outcomes. In this case, the survival time was higher than other cases that used pericardiocentesis alone. This report has opened an area of cardiology requiring investigation in the future.
