Abstract

BACKGROUND

Due to compactness and cheapness, smartphone ECG (sECG) could be very useful to equine practitioners. However, previous studies have evaluated the accuracy of sECG in hospitalised horses only. Different conditions in the field could influence the accuracy of the device. The aim of this study is to compare the accuracy of sECG in field and in hospital conditions.

METHODS

This is a prospective study. Paired standard base-apex ECG (stECG) and sECG were recorded in hospitalised horses and in subjects examined in field conditions. ECGs were analysed for heart rate and rhythm, presence/type of arrhythmias, presence/duration of artefacts, electrocardiographic waves and interval parameters by a blinded clinician. Statistical analysis evaluated the agreement between stECG and sECG and the differences in the prevalence of artefact in field and hospital conditions.

RESULTS

Nineteen (hospital) and 40 (field) paired ECGs were analysed. Agreement between stECG and sECG was found for heart rate and rhythm, evaluation of atrioventricular block and premature complexes, P wave and PQ interval duration, and QRS complex duration and polarity. No differences were found between artefacts recorded in hospital and in field conditions.

CONCLUSION

sECG is a feasible tool for evaluation of rhythm in horses and is as accurate in field as in ambulatory conditions.

摘要

背景

由于智能手机心电图（sECG）体积小巧且价格低廉，对马医来说可能非常有用。然而，以往的研究仅评估了住院马匹中sECG的准确性。野外的不同条件可能会影响该设备的准确性。本研究的目的是比较野外和医院条件下sECG的准确性。

方法

这是一项前瞻性研究。在住院马匹和野外检查的对象中记录配对的标准基-尖心电图（stECG）和sECG。由一位不知情的临床医生分析心电图的心率、节律、心律失常的存在/类型、伪迹的存在/持续时间、心电图波形和间期参数。统计分析评估了stECG和sECG之间的一致性以及野外和医院条件下伪迹发生率的差异。

结果

分析了19对（医院）和40对（野外）配对心电图。发现stECG和sECG在心率和节律、房室传导阻滞和早搏复合体的评估、P波和PQ间期持续时间以及QRS复合体持续时间和极性方面具有一致性。在医院和野外条件下记录的伪迹之间未发现差异。

结论

sECG是评估马匹节律的一种可行工具，在野外和门诊条件下一样准确。
