Heart Diseases in Reptiles: Diagnosis and Therapy.

The notion that poikilotherms do not suffer from cardiovascular conditions is being increasingly challenged as diagnostic tools used in companion animal practice are applied to reptiles. However, the cause, diagnosis, and treatment of cardiac conditions in reptiles is difficult because of the scarcity of published literature. Auscultation, electrocardiography, radiography, and ultrasonography are helpful diagnostic techniques in herpetologic practice. Although the pharmacokinetics and pharmacodynamics of cardiovascular drugs are poorly understood in these animals, basic principles remain applicable; these include pharmacologic and nonpharmacologic interventions. Further research is needed to establish species-specific cardiac reference ranges and evidence-based treatment options.
