Coronary artery occlusion is a very important problem in human medicine. A great progress in the treatment was the introduction of stents. The most popular are drug-eluting stents, which prevent restnosis. Nowadays, more than 30 different types of stents are implanted into the coronary arteries, and these stents are still being improved. Animal models make it possible to verify theoretical assumptions...
The influence of docosahexaenoic (DHA) acid obtained from a new generation of eggs on ventricular electrical function of 24 pigs with experimentally induced tachycardiomyopathy was described. Two groups were formed, 12 pigs had experimentally evoked tachycardiomyopathy and were getting standard feed (control group TIC). Twelve pigs with tachycardiomyopathy received feed with an addition of a dietary...
Heart rate turbulence (HRT) is a new electrocardiographic parameter used in human medicine to predict the possibility of death in patients with cardiac diseases. There is no information about HRT in healthy dogs and those with cardiac diseases. The aim of the present study was to compare the HRT in healthy Boxers dogs with Boxers with mild and moderate subaortic stenosis (SAS), to disclose the relationship...
The duration of electrocardiographic (ECG) parameters: PQ, QT and R-R intervals change during long-term and short-term observation as the consequence of the fluctuations in autonomic nervous system activity among others dependent on the exercise and resting. There is no data of horse breed influence on these parameters. The aim of the study was to assess the duration and the variability of the PQ,...
Nonpharmacological methods of treating cardiovascular diseases are becoming increasingly popular in veterinary cardiology. These methods often result in a complete and permanent cure of the patient and are a viable alternative to pharmacological treatment. This article presents selected nonpharmacological methods of treating cardiovascular diseases applied by the authors at the Department of Internal...
Heart rate turbulence (HRT) is modulated by the baroreceptor reflex and it was suggested that it could be used as a measure of autonomic dysfunction. Impaired HRT is of a significant prognostic value in humans after myocardial infarction, suffering from dilated cardiomyopathy and patients with heart failure. So far no studies were performed assessing the importance of HRT in dogs. The aim of this...
The aim of this study was to demonstrate the diagnostic accuracy of P-wave dispersion in predicting recurrence of atrial fibrillation in dogs with sinus rhythm restoration after external cardioversion. The study was performed on 15 dogs, which underwent electrical external cardioversion after atrial fibrillation. Nine-lead surface electrocardiogram of each dog was recorded 1 min after the cardioversion...
The electrocardiographic examination was performed in 33 training horses (2-16 years of age, 11 males and 22 females). Einthoven and precordial leads (I, II, III, aVR, aVL, aVF, CV₁, CV₂,CV₄) were used. The ECG was performed in resting horses and immediately after exercise (10 min walk, 15 min trot, 10 min canter) using a portable Schiller AT-1 3-channel electrocardiograph, with a paper speed of 25...
The study presents a comparison of the results received from dogs with dilated cardiomyopathy (DCM) that died during the first 30 d of observation and from dogs with DCM that survived the first 30 d after the ECG. No differences were noted in the duration of QT or QTc in healthy dogs and dogs with DCM. QTcd was significantly higher in dogs with DCM and in dogs with DCM, which did not survive over...
Results of supravital and post-mortem observation of embolic-thrombotic complications in dogs, in the course of endotoxaemia induced by pyometra and phlegmonous pneumonia due to infection with Psendomons aeruginosa, or endomyocarditis caused by Staphylococcus aureus infection were described. Multiorgan embolic-thrombotic complications were diagnosed in all presented cases. Most probably, the complications...
The aim of this study was to evaluate systolic function of left ventricle in dogs with spontaneous mitral regurgitation by estimating the rate of pressure rise in the left ventricle (dP/dt). Ninety-three dogs of different breed and sex, with chronic degenerative valvular disease were examined. All dogs had echocardiography examination with dP/dt estimation assessed from mitral regurgitant jet using...
