Plain-English summary
A Boxer dog underwent a 24-hour heart monitoring test because of irregular heartbeats. The vet analyzed the dog's heart rhythm before and after giving a medication called sotalol. After treatment, the dog's heart showed a pattern where certain intervals between beats were less common, which is referred to as a "zone of avoidance." While the study suggests that sotalol improved this heart rhythm pattern, more research is needed to understand its significance and any potential benefits for the dog's health.

Abstract
The RR intervals of sinus and ventricular beats were determined by analysis of a 24-h ambulatory electrocardiogram in a Boxer before and after treatment with sotalol. These RR intervals were plotted using tachograms, histograms, and Poincaré plots. The tachogram demonstrated a 'band' wherein a range of RR intervals was infrequent, the histogram did not take the form of a single Gaussian distribution of RR intervals, and the Poincaré plot showed nonhomogeneous beat-to-beat variability. This type of patterning was described as a "zone of avoidance" potentially caused by the clustering of beats within specific ranges. Treatment with sotalol enhanced the "zone of avoidance". Further investigation is needed to understand the mechanism for this observation as well as any clinical implications.
