Abstract
RATIONALE
Complete heart block (CHB) is a common clinical manifestation. Systemic sclerosis (SSc) is a rare etiology of CHB that has not received enough attention. Whether pacemaker implantation is required remains inconclusive, especially when patients have no symptoms or mild symptoms of CHB.
PATIENT CONCERNS
In this study, we report the case of a 48-year-old Chinese male who suffers from SSc and CHB.
DIAGNOSE
The patient was previously diagnosed with left anterior hemiblock (LAHB) and right bundle block with normal heart function. CHB was observed on a regular follow-up electrocardiogram (ECG) examination 1 month before his hospitalization.
INTERVENTIONS
A permanent dual chamber pacemaker was implanted.
OUTCOMES
The patient responded well to pacemaker implantation treatment, and his exertional dyspnea disappeared.
LESSONS
The occurrence of heart block associated with SSc often appears concealed. The case highlights the importance of regular follow-up of a patient with SSc. Pacemaker implantation might be unavoidable if CHB is secondary to SSc, even if it is asymptomatic.
