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.
摘要
在一只拳师犬接受索他洛尔治疗前后，通过分析其24小时动态心电图来确定窦性和室性搏动的RR间期。使用心动图、直方图和庞加莱图来绘制这些RR间期。心动图显示出一个“带”，其中一系列RR间期不常见，直方图并非RR间期的单一高斯分布形式，庞加莱图显示逐搏变异性不均匀。这种类型的模式被描述为可能由特定范围内搏动的聚集引起的“回避区”。索他洛尔治疗增强了“回避区”。需要进一步研究以了解这一观察结果的机制以及任何临床意义。
