A novel association between sinus node dysfunction and an SCN5A variant presenting as persistent symptomatic bradycardia in a young adult

Figures

• 

  Figure 1. Electrocardiogram obtained at the time of presentation demonstrating sinus bradycardia with a premature atrial contraction.

• 

  Figure 2. Telemetry monitoring during the patient’s inpatient evaluation demonstrating a 5.5-second sinus pause.

• 

  Figure 3. Sinus node electroanatomical maps depicted from the right lateral view (left) and posterior view (right), which were obtained at baseline and which confirmed a high right atrial sinus focus. The sinus node is depicted in red, which represents the earliest electrical impulse.
