1Department of Small Animal Clinical Sciences, College of Veterinary Medicine, Michigan State University, 736 Wilson Rd, East Lansing, MI 48824, USA.
概括
为了检测大多数心室节律失常 (VAs) 在狗中,三天的门诊心电图 (Holter) 监测是足够的. 对于R-on-T事件可能需要四天,以平衡诊断产量和监测持续时间.
科学领域:
- 兽医心脏病学 兽医心脏病学
- 诊断成像 诊断成像 诊断成像
- 狗的健康 狗的健康
背景情况:
- 门诊心电图 (Holter) 监测对于诊断狗的心律失常至关重要.
- 了解霍尔特监测的最佳持续时间对于最大限度地提高诊断产量,同时最大限度地降低患者负担至关重要.
- 节律失常发生的日常变化可能会影响短期监测的有效性.
研究的目的:
- 确定霍尔特监测的最佳持续时间,以检测狗的腹腔失常 (VAs).
- 用七天的记录来评估VA的日常自发变化.
- 为了确定扩展霍尔特监测的诊断回报减少的点.
主要方法:
- 追溯对124只狗的霍尔特记录的审查,其中87个符合VA或相关症状的纳入标准.
- 使用百分比变化系数 (CV%) 评估每日VA负担的变化.
- 贝叶斯概率建模用于分析七天监测期间的节律失常检测率.
主要成果:
- 每日心室早产综合体 (VPC) 频率显示出显著的变化 (CV% 8-188%).
- 检测到>1000个VPC或心室动脉冲动期,在三天后停滞.
- 检测超过100个VPC在两天后停滞不前;R-on-TVPC需要四到五天才能增加检测.
- 对心律失常检测的监测持续时间在治疗 (第3天的高原) 和未治疗的狗之间有所不同 (持续增加到第5天).
结论:
- 建议在狗中检测大多数VA时使用三天的霍尔特监测时间.
- 可能需要四天的监测,以最佳地检测R-on-T心室早产综合体.
- 这些发现提供了基于证据的指导,用于优化犬类心脏病学中的霍尔特监测协议.

Holter Monitor: 24-Hour Monitoring
321
Holter monitoring is a continuous electrocardiography (ECG) recording that tracks the heart's electrical activity over an extended period, generally 24 to 48 hours. This noninvasive diagnostic tool detects irregular heart rhythms that may not be captured during a standard ECG performed in a clinical setting.DeviceThe Holter monitor is a portable, small device connected to several electrodes on the patient's chest. These electrodes detect the heart's electrical signals and transmit them to the...

Pulse rhythm
940
Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...
