Left sided congestive heart failure due to severe aortic degeneration and insufficiency in a dog –a case report

Aortic degeneration is an uncommon finding in dogs with uncertain etiology, being associated with endocrine disorders which may induce hypercalcemia, hyperkalemia, or with toxicosis, renal disorders and endocarditis. This entity may develop a diastolic volume overload leading to left sided congestive heart failure. The aim of this study is to report and discuss a case of a dog with left sided congestive heart failure due to severe aortic regurgitation associated with myxomatous mitral valve disease and systemic hypertension

Retrospective evaluation of notched and fragmented QRS complex in dogs with naturally occurring myxomatous mitral valve disease

Myxomatous mitral valve disease (MMVD) is the most common cardiac disease in dogs. The association of QRS notching (nQRS) or fragmentation (fQRS) with disease severity is currently unknown. The study objective was to assess the prevalence of nQRS and fQRS in dogs with MMVD and its severity according to ACVIM classification and to compare the results with a group of healthy dogs. This retrospective cross-sectional study included 34 healthy control dogs and 155 dogs with spontaneous MMVD (42% of dogs in class B1, 23% in class B2 and 35% in class C). fQRS was defined as nQRS complexes in two contiguous leads in the frontal plane (leads I and aVL) and (II, III or aVF). A one-way ANOVA with Bonferroni post-hoc test was used to assess the differences in continuous data between control and MMVD groups. Of the MMVD group, 58% showed nQRS in at least one lead and 27% presented fQRS. There was no difference between the number of leads with a nQRS and disease severity (p ¼ 0.75) nor did the number of leads with a nQRS correlate with left atrial size (r ¼ 0.48; p ¼ 0.5). The number of dogs with fQRS did not differ among classes of MMVD (p ¼ 0.21). nQRS and fQRS were more prevalent in dogs with MMVD compared to control dogs (p < 0.01). This study did not identify any relationship between the number of leads with a nQRS and disease severity. However, dogs with MMVD had a higher prevalence of nQRS and fQRS compared to control group

Analysis of Poincaré plot derived from 5-min electrocardiography in dogs with myxomatous mitral valve disease

Background: Evaluation of heart rate variability (HRV) is used for risk assessment in a variety of cardiac diseases including myxomatous mitral valve degeneration (MMVD).Objectives: To compare the geometric analysis of HRV using visual patterns of Poincaré plot among different classes of MMVD in dogs and to analyse the differences in beat-to-beat variability using tachograms and sequential Poincaré plots among different shapes.Animals and methods: Healthy and MMVD dogs were retrospectively reviewed. Five-minute ECG data was used to create Poincaré plots and shapes were compared among groups. Furthermore, a sub-analysis of 50 consecutive R–R intervals was performed. Pearson Chi-square with adjusted standardized residuals was used to compare the categorical data between groups.Results: Fifteen healthy dogs and 157 dogs with MMVD were included in the study. Normal and B1 groups showed a predominance of triangular shape (73% and 60% respectively; p < 0.05). In B2 group the predominant shape was comet (40%; p < 0.05) while comet and torpedo were predominant in Ca group (41% and 36% respectively; p < 0.05). Visual geometric analysis revealed a lower dispersion of the cloud clustering towards the left lower corner of the plot with MMVD progression. Diamond and triangle revealed a lower mean heart rate compared to comet and torpedo shapes (p < 0.01). Interclass correlation between 3 observers was 0.906 (95% CI of 0.8 − 0.96).Conclusions: Poincaré plot shape changes with MMVD progression suggesting that geometrical analysis of HRV in dogs with cardiac conditions could be a useful tool in the risk assessment and further studies are warranted

Short-term heart-rate variability in healthy small and medium-sized dogs over a five-minute measuring period

Five-minute heart-rate variability (HRV) measurement is a useful tool for assessing the autonomic nervous system (ANS) balance in humans, but there are no studies on healthy dogs. The aim of the study was, therefore, to provide the reference ranges in small and medium-sized breeds for short-term HRV time and frequency domain (TFD) analyses

Short-term heart-rate variability in healthy small and medium-sized dogs over a five-minute measuring period

Introduction: Five-minute heart-rate variability (HRV) measurement is a useful tool for assessing the autonomic nervoussystem (ANS) balance in humans, but there are no studies on healthy dogs. The aim of the study was, therefore, to provide thereference ranges in small and medium-sized breeds for short-term HRV time and frequency domain (TFD) analyses. Materialand Methods: A total of 79 healthy dogs were included in the study between 2015 and 2019. Grouping by age with thebreakpoint at six years and subgrouping by reproductive status and sex was imposed. All the dogs were included after physicaland cardiological examinations and blood analyses. The TFD of HRV were analysed from a five-minute-long digital ECGrecording after removal of non-sinus complexes. Results: There were no statistically significant differences in any TFDparameters between age, reproductive status or sex groups. A mild increase in all time domain parameters and the high-frequency(HF) band was observed in older dogs, and the low frequency (LF):HF ratio decreased in these dogs. In males, the time domainparameters and HF band increased slightly. Conclusion: The normal ranges for HRV derived from short-term ECG recording inthe usual clinical environment now have proposed reference ranges. Our findings suggest that accommodation time, age, sex, orreproductive status do not influence the results derived from these recordings, indicating that this method is reliable for assessingthe ANS function in small and medium-sized dog breed
