“…11 Subsequent studies have demonstrated TVEC to be effective (initial success rate of 98%) with few adverse effects. [11][12][13][14][15] Intra-and postoperative risks and complications are reportedly low. 15 For these reasons, TVEC has gained popularity in several referral institutions.…”

Background: Whether electrical cardioversion of cardiac arrhythmias results in cardiomyocyte damage is unknown. Objective: To describe effect of transvenous electrical cardioversion (TVEC) on plasma cardiac troponin I (cTnI) concentration in horses.Animals: All horses presented to the Cornell University Hospital for Animals for cardioversion of atrial fibrillation between May 2006 and October 2008 were eligible for inclusion in the study. Owners of 14 horses elected for TVEC and each horse was then enrolled (16 procedures).Methods: Prospective observational study measuring concentrations of plasma cTnI before and after TVEC.Results: Median cTnI concentration increased from 0.045 ng/mL at baseline (range 0.0-0.20 ng/mL) to 0.11 ng/mL after TVEC (range 0.0-3.73 ng/mL) (P 5 .036). This increase was not associated with the number of shocks delivered, maximal energy delivered, cumulative energy delivered, chronicity of atrial fibrillation before cardioversion, or positioning of the pulmonary artery catheter.Conclusions: The increase in cTnI is unlikely to be clinically important. The increase might be correlated with persistent atrial dysfunction after TVEC, suggesting that a longer convalescent period after the procedure could be warranted.

“…Transvenous electrical cardioversion (TVEC) has been reported to be of higher efficacy than transthoracic cardioversion in humans and requires substantially lower energy levels. Successful TVEC using a conventional biphasic defibrillator has been described in horses but has not been reported in camelids . Transthoracic electrical cardioversion was attempted in the llama diagnosed with lone AF in this study (up to 200 J) but was also unsuccessful in restoring sinus rhythm.…”

BackgroundThere is limited information on the incidence of clinical signs, concurrent illness and treatment options for atrial fibrillation (AF) in New World Camelids (NWC).ObjectiveDescribe clinical signs and outcome of AF in NWC.AnimalsEight New World Camelids admitted with AF.MethodsA retrospective observational study of camelids diagnosed with AF based on characteristic findings on electrocardiogram (ECG).ResultsAll animals had an irregularly irregular heart rhythm detected on physical examination and 4 cases had obtunded mentation on admission. Three camelids were diagnosed with AF secondary to oleander intoxication, 3 animals had underlying cardiovascular disease, 1 was diagnosed with lone AF and 1 had AF diagnosed on examination for a urethral obstruction. Five of eight animals survived to discharge and nonsurvivors consisted of animals which died or were euthanized as a result of cardiovascular disease (2/8) or extra‐cardiac disease unrelated to the AF (1/8).Conclusions and Clinical ImportanceAtrial fibrillation occurs in NWC in association with cardiovascular disease, extra‐cardiac disease or as lone AF. Amiodarone and transthoracic cardioversion were attempted in one llama with lone AF, but were unsuccessful. Atrial fibrillation was recorded in 0.1% of admissions.

“…Navigation of equipment through vessels and cardiac chambers relies on good ultrasonographic anatomical landmarks. More and more centres offer transvenous electrical cardioversion which requires accurate positioning of catheters in right atrium (RA) and left pulmonary artery (lPA) [9][10][11][12][13][14]. Pacemaker lead implantation, cardiac biopsy procedures and occluder implantation are performed with ultrasound guidance [15][16][17][18].…”
