“…3,7,8,16,17 Because of the high frequency of electrical abnormalities in this breed, Holter examination was suggested to be the best test for detecting early changes, 3,7,17 and thus Holter examinations have been evaluated and recommended in Doberman Pinschers as well as in other breeds for the purpose of diagnostic and therapeutic considerations. 3,7,17,[19][20][21][22][23][24][25] However, availability of Holter recorders and expense of this technique may preclude its use in many dogs. 18,26 Consequently, many veterinarians currently base diagnostic and therapeutic decisions on lead II ECGs performed for only a brief period, while the dog is in the hospital.…”

Background: Ventricular premature contractions (VPCs) are common in the occult stage of cardiomyopathy in Doberman Pinschers. Although the gold standard for detecting arrhythmia is the 24-hour ambulatory electrocardiography (ECG) (Holter), this method is more expensive, time-consuming and often not as readily available as common ECG.Objectives: Comparison of 5-minute ECGs with Holter examinations. Animals: Eight hundred and seventy-five 5-minute ECGs and Holter examinations of 431 Doberman Pinschers. Methods: Each examination included a 5-minute ECG and Holter examination. A cut-off value of 4100 VPCs/24 hours using Holter was considered diagnostic for the presence of cardiomyopathy. Statistical evaluation included calculation of sensitivity, specificity, positive predictive value, and negative predictive value.Results: Holter examinations revealed 4100 VPCs/24 hours in 204/875 examinations. At least 1 VPC during a 5-minute ECG was detected in 131 (64.2%) of these 204 examinations. No VPCs were found in the 5-minute ECG in 73 (35.8%) examinations of affected Doberman Pinschers. A 5-minute ECG with at least 1 VPC as cut-off had a sensitivity of 64.2%, a specificity of 96.7%, a positive predictive value of 85.6% and a negative predictive value of 89.9% for the presence of 4100 VPCs/24 hours.Conclusions and Clinical Importance: A 5-minute ECG is a rather insensitive method for detecting arrhythmias in Doberman Pinschers. However, the occurrence of at least 1 VPC in 5 minutes strongly warrants further examination of the dog, because specificity (96.7%) and positive predictive value (85.6%) are high and could suggest occult cardiomyopathy.

Early identification of arrhythmias in dogs showing doxorubicin-induced cardiomyopathy was studied. Ten healthy dogs were assigned to groups A (n=5) and B (n=5). Dogs from group B were given doxorubicin 30mg/m 2 intravenously, every 21 days, until a cumulative dose of 180mg/m 2 or 240mg/m 2 was reached. Dogs from group A (used as control) were administered saline intravenously at the same group B intervals. As soon as myocardium dysfunction was observed in dogs from group B, determined by a shortening fraction below 20%, increased E-point to septal separation above 0.7cm, and increased end-systolic left ventricular volume index (61.4ml/m 2 ), a 24-hour Holter was recorded in all dogs from both groups. There was an increase of minimum heart rate (44.6%) and mean heart rate (41.7%) in animals from group B in comparison with the control animals. Either supraventricular or ventricular arrhythmias were observed, despite group B dogs showed higher occurrence of supraventricular arrhytmias. Holter monitoring is efficient in early determination of heart rate and cardiac rhythm alterations in dogs showing doxorubicin-induced myocardial dysfunction.Keywords: dog, doxorubicin, eletrocardiogram, cardiopathy RESUMO O estudo consistiu na identificação precoce da ocorrência de arritmias em cães com cardiomiopatia dilatada experimental induzida pela doxorrubicina (DOX).

“…To include or exclude arrhythmias as a cause of an episode of weakness or syncope, an abnormal or normal electrocardiogram must be documented during a clinical episode (Kapoor 2000). Such documentation may require continuous ambulatory, rather than standard, electrocardiography (ECG) recordings (Goodwin 1998). Ambulatory electrocardiography (AECG) techniques have reached a sensitivity and specificity of over 90 per cent in the detection of arrhythmias in humans, although it has been found that the use of cardiac event recorders for up to three months provided superior data and was more cost effective than 48-hour AECG monitoring in assessing intermittent palpitations (Kinlay andothers 1996, Roche andothers 1997).…”

Ambulatory electrocardiography techniques are superior to standard electrocardiography in evaluating rhythm disturbances in dogs with episodic weakness or collapse. Disadvantages include cumbersome equipment, short recording periods and an inherent delay in trace analysis. A small programmable cardiac event recorder with combined automatic and owner-triggered recording capability was evaluated in 13 healthy dogs in a hospital environment. The unit was well tolerated and produced diagnostic recordings directly to a personal computer, with useful information about continuous heart rate. It detects premature complexes, pauses and bradycardias according to programmed detection thresholds. These events were counted frequently but trace review revealed concerns regarding specificity. Recordings were often triggered by sinus arrhythmia, sinus tachycardia and unclassifiable rate changes rather than by clinically significant arrhythmias. Correct detection of ventricular ectopic complexes, a single supraventricular premature complex, sinus arrest and second-degree atrioventricular block occurred in individual dogs. Visual review of all automatically recorded events was essential and significantly increased the time required for event recording analysis. Manual recordings might be more useful and the overall results suggest that further studies are warranted to evaluate the system in clinical cases in the home environment.
