“…All cats had higher heart rates in the first hour after Holter placement, unrelated to the time of the day. This first hour effect has previously been reported in other canine and feline studies (Jackson et al, 2014;Gelzer et al, 2015), and is likely caused by increased sympathetic tone due to stress (manipulation, hair clipping etc.). Additionally, for the entire recording time, the median heart rate in the different groups was relatively high, and we could not document any correlation between heart rate and time of the day.…”

“…Multiple preparations of diltiazem are available; treatment should be started at a modest dosage for the preparation chosen and titrated to achieve heart rate control. Ideally, mean heart rate as measured by Holter monitoring in dogs with well‐controlled signs of CHF receiving stable drug dosage regimens should be close to normal or at least <125 beats per minute .

This report, issued by the ACVIM Specialty of Cardiology consensus panel, revises guidelines for the diagnosis and treatment of myxomatous mitral valve disease (MMVD, also known as endocardiosis and degenerative or chronic valvular heart disease) in dogs, originally published in 2009. Updates were made to diagnostic, as well as medical, surgical, and dietary treatment recommendations. The strength of these recommendations was based on both the quantity and quality of available evidence supporting diagnostic and therapeutic decisions. Management of MMVD before the onset of clinical signs of heart failure has changed substantially compared with the 2009 guidelines, and new strategies to diagnose and treat advanced heart failure and pulmonary hypertension are reviewed.

“…In contrast, ambulatory monitoring allows HR assessment outside the hospital setting, perhaps more accurately representing the dog's HR fluctuations during a normal daily routine in the familiar home environment. In‐clinic ECG recordings have been shown to correlate with, but overestimate, the Holter recording‐derived mean HR in dogs with AF …”

BackgroundAtrial fibrillation (AF) usually is associated with a rapid ventricular rate. The optimal heart rate (HR) during AF is unknown.Hypothesis/ObjectivesHeart rate affects survival in dogs with chronic AF.AnimalsForty‐six dogs with AF and 24‐hour ambulatory recordings were evaluated.MethodsRetrospective study. Holter‐derived HR variables were analyzed as follows: mean HR (meanHR, 24‐hour average), minimum HR (minHR, 1‐minute average), maximum HR (maxHR, 1‐minute average). Survival times were recorded from the time of presumed adequate rate control. The primary endpoint was all‐cause mortality. Cox proportional hazards analysis identified variables independently associated with survival; Kaplan‐Meier survival analysis estimated the median survival time of dogs with meanHR <125 bpm versus ≥125 bpm.ResultsAll 46 dogs had structural heart disease; 31 of 46 had congestive heart failure (CHF), 44 of 46 received antiarrhythmic drugs. Of 15 dogs with cardiac death, 14 had CHF. Median time to all‐cause death was 524 days (Interquartile range (IQR), 76–1,037 days). MeanHR was 125 bpm (range, 62–203 bpm), minHR was 82 bpm (range, 37–163 bpm), maxHR was 217 bpm (range, 126–307 bpm). These were significantly correlated with all‐cause and cardiac‐related mortality. For every 10 bpm increase in meanHR, the risk of all‐cause mortality increased by 35% (hazard ratio, 1.35; 95% CI, 1.17–1.55; P < 0.001). Median survival time of dogs with meanHR<125 bpm (n = 23) was significantly longer (1,037 days; range, 524‐open) than meanHR ≥125 bpm (n = 23; 105 days; range, 67–267 days; P = 0.0012). Mean HR was independently associated with all‐cause and cardiovascular mortality (P < 0.003).Conclusions and Clinical ImportanceHolter‐derived meanHR affects survival in dogs with AF. Dogs with meanHR <125 bpm lived longer than those with meanHR ≥ 125 bpm.
