RESUMO
O caso clínico sugere uma forma rara de canalopatia mista, cujo sintoma clínico e eletrocardiográfico indicava taquicardia ventricular polimórfica catecolaminérgica (TVPC). Porém, ao realizar o teste ergométrico, no pós-esforço, quando há predomínio do sistema nervoso parassimpático, nota-se a indução de eletrocardiograma (ECG) compatível com Brugada do tipo I. Outro aspecto importante foi a transmissão hereditária observada neste caso, em que os avós do paciente eram primos de primeiro grau e houve seis casos de morte súbita cardíaca (MSC) nas gerações subsequentes, com irmão que teve MSC aos 5 anos durante uma crise de choro, mostrando um importante fator genético e familiar relacionado às canalopatias.
ABSTRACT
The clinical case suggests a rare form of mixed channelopathy, whose clinical and electrocardiographic symptom suggested catecholaminergic polymorphic ventricular tachycardia (CPVT). However, when the exercise test was performed, during post-exercise, where there is a predominance of the parasympathetic nervous system, there was an electrocardiogram (ECG) induction compatible with Brugada type I. Another important aspect was the hereditary transmission observed in this patient, whose grandfathers were first cousins, and 6 cases of sudden cardiac death (SCD) were observed in subsequent generations and one brother had SCD at 5 years of age during a crying episode, showing an important genetic and familial factor related to channelopathies.
