Sick Sinus Syndrome in a Female Patient with Chagas Disease. Case Report

Chagas disease is a zoonosis transmitted by Trypanosoma Cruzi, which has become a public health problem worldwide. The infection can be acute, chronic phases and reactivations, characterized by heart involvement. We report the case of a 33-year-old woman with stabbing chest pain, as well as hemiparesis in the left arm managed for 8 weeks, with persistent chest pain, electrocardiogram (ECG) showing a heart rate of 40 bpm. She is referred to a cardiologist who requests a Holter which shows pauses of 5.4 seconds and a transthoracic echocardiogram with LVEF 56%, PASP 24 mmHg; anti trypanosoma cruzi IgG antibodies were requested with a positive result, starting management based on nifurtimox; candidate patient for management with a double-chamber pacemaker, with remission of symptoms. In recent years, our knowledge about Chagas disease has expanded, electrocardiography is the most useful individual examination technique for these patients. Late manifestations include sinus node dysfunction leading to severe bradycardia, high-grade AV block, etc. Chagas disease should be suspected in all patients with an epidemiological history compatible with symptoms of cardiac involvement. and we believe that active intervention in endemic areas of the disease is especially relevant.
