Key result
Experimental infection of adult dogs with Trypanosoma cruzi caused transient arrhythmias, with the main tachyarrhythmic changes concentrated in the acute phase concomitantly to the parasitemia peak.
Population
Adult dogs infected with Trypanosoma cruzi, Bolivian strain (experimental Chagas cardiomyopathy model)
Design
Preclinical
Follow-up
Through acute and chronic phases

Transient arrhythmias peak acutely in canine Chagas models; leaves open human translation and chronic-phase relevance.
Dynamic electrocardiography effectively identifies transient arrhythmias in experimental Chagas cardiomyopathy, demonstrating that severe tachyarrhythmias peak during the acute phase of infection.
Alves et al. (2012) studied Experimental Chagas Cardiomyopathy. Trypanosoma cruzi infection (Bolivian strain) was evaluated on Electrocardiographic changes (resting and dynamic). Experimental infection of adult dogs with Trypanosoma cruzi caused transient arrhythmias, with the main tachyarrhythmic changes concentrated in the acute phase concomitantly to the parasitemia peak.
