“…Similarly, the relatively large number of respondents who used lidocaine and sotalol could be explained by the fact that ventricular tachycardia was the fourth most diagnosed arrhythmia in this study. Both sotalol and lidocaine are described a first‐line treatment for ventricular tachycardia 17 . We also tried to speculate a few potential reasons why amiodarone, mexiletine, magnesium and esmolol were used so infrequently.…”

Background Diagnosis as well as management of arrhythmias in dogs can be challenging for veterinary practitioners. The aim was to describe ECG availability and use, as well as the diagnostic and therapeutic experiences and preferences of Flemish veterinarians regarding cardiac arrhythmias in dogs. Methods Cross‐sectional online survey among veterinarians in Flanders (Belgium). Results An ECG device was available for 55 out of 102 respondents (54%) and 41 (43%) claimed to use it in case of arrhythmia suspicion. Insufficient knowledge about ECG interpretation and immediate patient referral upon detection of an abnormal heart rhythm were the most important reasons for not having, or not using, an ECG. About half of the respondents (56%) had never used anti‐arrhythmic drugs in dogs, although only a few reported having had a negative experience. Frequently provided reasons for not using anti‐arrhythmic drugs included insufficient knowledge and a low number of dogs with arrhythmias. Conclusion Most veterinarians reported having little or no expertise with arrhythmias in dogs. Electrocardiogram availability and use among respondents was moderate and too often restricted by insufficient ECG interpretation skills. Continued efforts are needed to increase the confidence and knowledge of veterinarians about arrhythmias in dogs.

“…We also tried to speculate a few potential reasons why amiodarone, mexiletine, magnesium and esmolol were used so infrequently. For example, amiodarone is considered a second‐line drug for atrial fibrillation 16 and ventricular arrhythmias 17 . Mexiletine has availability issues in Europe and is expensive for long‐term treatment.…”

“…peak plasma level sotalol two to four hours after oral intake in humans) and the onset of SCD 55 minutes after attaching the Holter ECG, it is debatable whether oral administration of antiarrhythmic drugs prior to Holter ECG monitoring could have potentially reduced VA burden, or prevented SCD during Holter in this cat (Hanyok, 1993). Besides, whilst antiarrhythmic drugs have been shown to reduce VA burden in some cases, studies in veterinary medicine have generally failed to show any reduction in the occurrence of SCD (Mac-Donald et al, 2011;da Silva, 2018). A continuous rate infusion of lidocaine or esmolol might have reduced VA frequency during Holter ECG (Verschoor-Kirss et al, 2022).…”

An asymptomatic three-year-old male European Domestic Shorthair cat was referred for an irregular heart auscultation. Apart from localized concentric left ventricular septal hypertrophy, echocardiography was normal. However, ventricular ectopy was observed on electrocardiography (ECG) during echocardiography. The cat died suddenly 55 minutes after the start of the subsequent Holter ECG. Analysis showed sinus rhythm interrupted by 192 single ventricular premature complexes, a ventricular couplet, two incidents of ventricular bigeminy and two runs of ventricular tachycardia (VT). The last run of VT deteriorated into ventricular fibrillation (VF) and ultimately cardiac arrest. Structural heart disease including mild feline hypertrophic cardiomyopathy or myocarditis, primary arrhythmia (channelopathy) or extra-cardiac disease were maintained as differential diagnosis. Unfortunately, a necropsy was declined leaving no definitive diagnosis available. In this case report, it is shown that VF due to ventricular ectopy is a possible cause of SCD even in asymptomatic cats with only mild echocardiographic signs of structural heart disease.
