“…The primary goal of long-term ECG monitoring is the improvement of diagnostic yield. A diagnostic advantage with prolonged duration of monitoring for detection of arrhythmia events has been reported for Holter/event monitors (Miller et al 1999, Bright et al 2000, Wess et al 2010) and for wireless devices (Lobodzinski 2013, Rosenberg et al 2013, Turakhia et al 2013, Barret et al 2014, Schreiber et al 2014, Schrivastav et al 2014. The results of our study are in agreement that the longer monitoring time increases the diagnostic yield.…”

“…The ECG signal changes with the position of the body, and in the case of rapid movements of the thorax, the evaluation of the ECG signal can be more difficult or impossible due to the multitude of artefacts and changes in the shape and size of the signal. Excessive motion artefacts are also common in ECG monitoring with Holter and event monitors, which are currently used for long-term monitoring in veterinary medicine (Miller et al 1999, Bright et al 2000. Another problem was the difficulty in firmly attaching the self-adhesive electrodes.…”

Objectives To evaluate the diagnostic utility of electrocardiogram data obtained by a wireless sensor from 36 dogs and four cats with suspected arrhythmias caused by cardiac or systemic diseases. Materials and Methods Wireless electrocardiographic recordings were obtained via two precordial electrodes attached to an electrocardiogram sensor connected to a smart device via low‐power Bluetooth technology. Cardiac rate, rhythm and duration of P‐QRS‐T waves were evaluated with VisECG® software. Fifteen‐ to 30‐minute wireless recordings were compared to standard electrocardiograms. Furthermore, the wireless sensor was used in 10 dogs and four cats for 24‐hour continuous electrocardiogram monitoring at home. Results When compared to standard electrocardiogram, equivalent results were obtained for heart rate and duration of different waves. Due to the longer recording time, more arrhythmias were diagnosed with the wireless device in 50% (15 of 30) of animals with arrhythmias. Satisfactory recordings were obtained when the dogs were resting, standing or walking but interpretation of the wireless electrocardiogram signal was not possible during strenuous physical activity. Clinical Significance Wireless electrocardiographic monitoring is a reliable and accurate method for identification of heart rate, arrhythmia and duration of electrocardiogram waves. A higher diagnostic yield of arrhythmias was documented with the wireless sensor due to prolonged monitoring. The device offers a good option for the long‐term monitoring of canine and feline cardiac rhythm.

“…s Key words syncope · fainting · orthostatic · reflex syncope · animal tory Holter recordings were described in 44 dogs [44], and the use of event loop recorders that allow longer recording periods has been described in 58 dogs and 2 cats [8].These techniques were used to establish arrhythmia as the cause of syncope, or to show that attacks were not due to arrhythmia. As in man, relevant arrhythmias often occurred in animals with structural heart disease.…”

Fainting (syncope) is unconsciousness due to insufficient cerebral circulation in the context of a temporary failure of the systemic circulation. This paper firstly aims to discuss fainting in animals, and secondly to discuss animal physiology to broaden the understanding of human fainting. Of the three major syncope types (cardiac, orthostatic and reflex syncope), only cardiac syncope occurs in animals as in man, through arrhythmia or output failure. Man's orthostatic fainting tendency has been blamed on his upright posture. A comparison with animals shows that giraffes, tree climbing snakes, and animals that quickly raise and lower their heads face more serious gravitational circulatory challenges than man, but do not appear to faint. Merely carrying the brain above the heart does not explain a fainting tendency, as the human heart-to-brain height is smaller than that of many mammals with similar blood pressure. Two evolutionary novelties may be to blame: the proportion of cardiac output going upwards to the brain is much larger than in apes, and man's large legs suggest that the volume lost to venous pooling is also larger. Emotional factors play a role in many reflex syncope events. Tonic immobility ('feigning death','playing possum') is not a good model, as it concerns immobility as a survival strategy of an attentive brain, rather than unconsciousness due to circulatory breakdown. Whether orienting and defense responses form a valid model remains to be proven. Emotional fainting may be uniquely human; how mental processes can shut down the circulation and thereby the brain needs serious study, as it may hold the key to syncope prevention.

“…Estudo com 51 cães cardiopatas evidenciou que 35% deles apresentaram síncope por algum tipo de arritmia, e o restante (65%) por outra causa (BRIGHT; CALI, 2000). A síncope pode estar associada a intensas bradicardias (bloqueio atrioventricular de terceiro grau ou doença do nodo sinusal), que diminuem o DC por diminuir excessivamente a FC, ou taquicardias sustentadas (taquicardia atrial ou ventricular), que podem diminuir o DC por comprometer o tempo de enchimento cardíaco (DAVIDOW; PROW; WOODFIELD, 2001;JOCHMAN-EDWARDS et al, 2002;ABBOT, 2008).…”

RESUMO:A doença valvular crônica de mitral é a enfermidade cardíaca mais comumente relatada em cães de pequeno e médio porte, adultos ou idosos. A síncope cardíaca é uma manifestação comumente observada, causada por diversos mecanismos. Objetivou-se relatar um caso desta doença em uma cadela da raça Teckel, com 16 anos de idade, que apresentava episódios recorrentes de síncope. Os episódios estavam associados com bradicardia, palidez de mucosas e aumento da pressão intratorácica. Excluindo-se outras causas de síncope, foi realizado o diagnóstico presuntivo de síncope neurocardiogênica, sendo a primeira descrição na medicina veterinária. PALAVRAS-CHAVE: Cardiologia.

NEUROCARDIOGENIC SYNCOPE IN A DOG WITH CHRONIC MITRAL VALVULAR DISEASE -CASE REPORTABSTRACT: Chronic mitral valvular disease is the most commonly acquired heart disease in middle-aged to elderly dogs in small to medium-size breeds. Cardiac syncope is a common manifestation observed in such disease, caused by several mechanisms. The purpose of this study is to report a case of several syncope episodes in a Teckel dog aged 16 years, presenting chronic mitral valvular disease. The episodes were associated with bradycardia, pale mucous membranes and increased intra-thoracic pressure. The presumptive diagnosis of neurocardiogenic syncope was reached by excluding other causes of syncope, which is the first description in veterinary medicine. KEYWORDS: Bezold-Jarisch reflex.

IntroduçãoA doença valvular crônica de mitral (DVCM) é a doença cardíaca adquirida mais comum em cães, que pode originar insuficiência cardíaca congestiva. É frequentemente reportada em cães adultos e idosos, de raças de pequeno e médio porte, sendo detectada em 30% dos cães com mais de 13 anos de idade (ABBOT, 2008). A síncope pode ser uma manifestação clínica de cães com esta doença. É definida como uma perda súbita e transitória da consciência, com iní-cio rápido e curta duração, ocorrendo recuperação espontâ-nea, rápida e completa (MOYA et al., 2009). Doenças cardíacas podem causar síncope por diminuição do débito cardíaco ...
