Chapter
Electrocardiography is a noninvasive technique employed to record the electrocardiogram (electrical activity of the heart plotted against the time) of the humans and animals. History of electrocardiography dates back to 1616 when Harvey discovered blood circulation, and later in 1887 Waller recorded the electrical activity of human heart for the fi...
Chapter
Heart failure is the final outcome of heart diseases and is characterized by cardiac pump failure. Heart failure can be due to cardiomyopathy, valve insufficiency, severe arrhythmia, or AV blocks. Clinical manifestations in heart failure are related to systolic dysfunction (forward failure) and/or diastolic dysfunction (backward failure). Timely co...
Chapter
Evaluation of the heart is an integral part of detailed clinical examination. In many exotic pets or in avian species, heart examination has not been given due attention as routine auscultation is not rewarding in chelonians due to hard shell, due to very fast heart rate in avian species or lack of basic information. In this chapter an attempt has...
Chapter
In urban areas cats are also being kept as pet animal, and their number is increasing in outpatient department (OPD) of pet clinics. Though prevalence of cardiac diseases in cats in India is not known, studies done abroad have indicated that cardiac diseases in cats are not uncommon. The diagnosis of cardiac diseases in cats is not an easy task bec...
Chapter
Correct interpretation of an electrocardiogram requires a systematic reading. Properly filled ECG strip facilitates its interpretation. Heart rate is easily calculated by counting the complexes in three second period (i.e. in 15 large squares or in 75 small squares on horizontal axis of ECG). Change in R-R interval and complexes unassociated with P...
Chapter
Sodium, potassium, and calcium are important ions which play a crucial role in the depolarization and repolarization of the cardiac muscle cells. It is logical if their concentration is not appropriate, contraction of the heart is affected. Similarly many physical (hypothermia or hyperthermia) and chemical agents (arsenic, lead, bufotoxins, theobro...
Chapter
There are four important valves in the heart, namely, the mitral valve, tricuspid valve, aortic valve, and pulmonary valve. Insufficiency of the valves leads to back flow of the blood from the left ventricle to left atrium (during ventricular systole), right ventricle to right atrium (during ventricular systole), aorta to left ventricle (during ven...
Chapter
Electrocardiography in ruminants is not as common as in canines and felines because of low prevalence of cardiovascular diseases. Traumatic reticulopericarditis and arrhythmias are commonly seen in cattle and buffaloes. In other ruminants arrhythmias are commonly observed. Most of them are asymptomatic and require no medical attention. Nevertheless...
Chapter
Cardiomyopathy is very common in dogs. It is classified as dilated, hypertrophic, and restrictive cardiomyopathy. Dilated cardiomyopathy is more common in males of large breeds. Atypical form of cardiomyopathy has been described in Boxer, Doberman and Cocker Spaniels. Exact etiology of cardiomyopathy is still debated. Diagnosis of cardiomyopathy re...
Chapter
Beside cardiac chamber enlargement, abnormalities in current flow pattern (conduction pathway) are equally important. Delay in intraventricular conduction leads to bundle branch and fascicular blocks. Electrocardiogram is the only diagnostic technique which is of great assistance in detecting these blocks. Importance of these blocks increases when...
Chapter
Electrocardiogram is a graph of the electrical activities of the heart as a consequence of depolarization and repolarization of cardiac cells during each heartbeat. The seat of the current generation in the heart is SA node. The current from SA node is passed to the atrium and the AV node to the bundle of His to the bundle branches to the Purkinje...
Chapter
As it has been described in earlier chapters, the electrocardiogram is the graphic representation of the electrical events occurring in the heart during depolarization and repolarization. The functioning of the heart is effected not only by the diseases of the heart itself but also by the diseases of other organs leading to alterations in the elect...
Chapter
Pericardial effusion, a disease of pericardium, is characterized by increased amount of fluid in the pericardial sac. It is of idiopathic or neoplastic origin. Symptoms of pericardial effusion are related with cardiac compensation leading to right heart failure. The presence of three clinical signs such as muffled heart sound, jugular venous disten...
Chapter
Cardiac diseases are common in canine population. Cardiac functions are compromised not only in primary cardiac diseases but also in diseases of other organs affecting the heart secondarily. So it is imperative to evaluate the heart in ailing dogs. Undoubtedly electrocardiography provides an important information about rate, rhythm, conduction dist...
Chapter
When the values of waves (P, QRS, T), segments (P-R segment, S-T segment), and intervals (P-R interval, Q-T interval, R-R interval) do not conform to normal values for the species of the animal under examination, it is said to be an abnormal electrocardiogram. Tall P wave (>0.4 mV), broad P wave (>0.04 s), tall R wave (>2.5 mV in dogs of small bree...
Chapter
Many heart diseases are associated with enlargement of atrium and/or ventricles. It is possible to detect enlargement not only of atrium and/or ventricles but also of their side involved (right or left) using electrocardiogram in canines. Enlargement of right or left atrium is reflected by tall P wave (0.4 mV) or broad P wave (>0.04 s), respectivel...
Chapter
Arrhythmias denote disturbances in cardiac rate, rhythm, and/or both and are very common in canines. Cardiac arrhythmias have been classified into various categories based on their basic abnormalities, heart rate, heart rhythm, and physio-anatomical basis or with regard to therapy. Impulses that generate outside the SA node are associated with arrh...
Chapter
Detection of abnormalities in an electrocardiogram requires a knowledge of basic electrocardiographic norms for the particular species of the animal under examination. Criterion for electrocardiographic norms for healthy animals of different species is different. Like other tests such as hemogram or biochemical values, electrocardiogram is also not...
Chapter
Cardiac functioning is affected not only by cardiac diseases (arrhythmias, conduction disturbances, ectopic focus, septal defects, vulvular defects, chamber size changes, pericardial effusions) but also by hemodynamic changes (dehydration, anemia), respiratory distress (hypoxia), ionic imbalances, inflammatory diseases of other organs, hormonal imb...
