Urine sodium concentration after intravenous furosemide in dogs with acute congestive heart failure and correlation with treatment efficacy.

Background: Poor natriuresis is a potential marker of diuretic resistance in dogs with acute congestive heart failure (CHF) but little is known about the relationship between urine sodium concentration (uNa) and frequency of successful decongestion. Supplemental O is a common treatment in dogs with severe CHF. The time from start to discontinuation of supplemental O therapy (DCSO ) typically reflects the time course and ease of decongestion.

Feasibility of electroanatomic mapping and radiofrequency catheter ablation in Boxer dogs with symptomatic ventricular tachycardia.

Background: Treatment for Boxers with ventricular tachycardia (VT) is limited. Electroanatomic mapping (EAM) facilitates identification of arrhythmogenic substrate for radiofrequency catheter ablation (RFCA).

Objective: Describe the use of EAM to guide RFCA in Boxers with VT.
