The study analyzed the effect of regular and monitored physical activity in patients (P) with Chagas disease (CD) and chronotropic incompetence using a blended sensor pacemaker. This was an open-label, longitudinal, prospective and randomized clinical trial. The 43 out of 50 selected P were evaluated in pre-ambulatory and 120 days after the randomization. 24 Pwere allocated to group G1 (with exercise activity - walking for 50 minutes at least 3 times per week) or G2 (without exercise activity; 19 P). The parameters recorded by the devices in percentages (%) were: "atrial sensing" (AS); atrial pacing (AP); time the patient remained at maximum sensor rate during physical activity (MSR), time the sensor detected mild to moderate physical activity (AT), time the sensor detected no physical activity (NAT - No activity), and the mean sensor rate (HR). The mean age was 65.58 ± 10.57 years, (58.14%) were women. After 120 days, MSR and NAT between G1 and G2 were statistically significant (p<0,05) The G1 presented better quality of life, according to AQUAREL and SF-36v2®.An improvement in telemetric data and quality of life was observed in chagasic P with a blended sensor who performed exercise compared with P who did not exercise.
