Introduction

The objective of this retrospective study was to describe the indications, complications, and long-term outcomes in a group of cats that received an epicardial pacing (EP) system.

Animals

Twenty client-owned cats.

Materials and methods

Medical records were reviewed for signalment, presenting complaint, primary electrocardiogram (ECG) diagnosis, presence of structural heart disease, presence of congestive heart failure (CHF), presence of major or minor complications, and survival time.

Results

The majority of cats were presented for syncope (n = 11), and the most common ECG diagnosis was advanced second-degree atrioventricular block (n = 9). Fifteen cats (15/20, 75%) had one or more major or minor complications. One cat died in the perioperative period as a result of a major complication. None of the variables evaluated were associated with a statistically significant increase in the occurrence of major or minor complications. The most common major complication was loss of ventricular capture (seven instances in six cats), which was successfully treated in all cases by increasing pacemaker output or replacing both the lead and the pulse generator. The most common minor complications were arrhythmias (n = 7) and sensing issues (n = 8). The overall median survival time (MST) was 948 days. No statistical difference in survival time was identified between cats that experienced a major complication and those that did not.

Conclusions

Although complications were common in this feline population after EP, major and minor complications were successfully treated.

对来自同一机构的 20 只猫的心外膜起搏器相关适应症、并发症和结果的回顾性评估

介绍

这项回顾性研究的目的是描述一组接受心外膜起搏 (EP) 系统的猫的适应症、并发症和长期结果。

动物

二十个客户拥有的猫。

材料和方法

审查医疗记录的信号、主诉、原发性心电图 (ECG) 诊断、结构性心脏病的存在、充血性心力衰竭 (CHF) 的存在、主要或次要并发症的存在以及生存时间。

结果

大多数猫出现晕厥（n = 11），最常见的心电图诊断是晚期二度房室传导阻滞（n = 9）。15 只猫 (15/20, 75%) 有一种或多种主要或次要并发症。一只猫在围手术期因严重并发症死亡。评估的变量中没有一个与主要或次要并发症发生率的统计学显着增加相关。最常见的主要并发症是心室捕获丧失（六只猫中有七例），通过增加起搏器输出或更换导线和脉冲发生器在所有情况下都成功治疗。最常见的轻微并发症是心律失常 (n = 7) 和感觉问题 (n = 8)。总体中位生存时间 (MST) 为 948 天。

结论

尽管 EP 后该猫科动物群体中常见并发症，但成功治疗了主要和次要并发症。
