participate in organized sports?

Should my patient with Complete Left Bundle Branch Block participate in organized sports?

Complete Left Bundle Branch Block


Need to know:

Asymptomatic, no spontaneous type II second-degree AV block or complete heart block

"Athletes with permanent or rate-dependent LBBB who do not develop spontaneous type II second-degree AV block (Mobitz) or complete heart block and who have no symptoms or heart disease identified by appropriate testing that otherwise precludes participation, can participate in all competitive athletics."

All sports = reasonable if conditions met and no other heart disease that would preclude participation

(Class I Recommendation; Level of Evidence C)

Symptoms

"In athletes with concerning symptoms, an EPS is recommended. An athlete with a normal HV interval and a normal AV conduction response to pacing can participate in all competitive sports unless otherwise restricted by their structural heart disease."

If EP study shows normal HV interval and normal AV conduction response to pacing, then all sports are acceptable (unless restricted by other heart disease)

(Class I Recommendation; Level of Evidence C)

Abnormal AV conduction (HV interval >90 ms or His-Purkinje block)

"Athletes with abnormal AV conduction characterized by an HV interval >90 ms or a His-Purkinje block should have pacemaker implantation."

Should have pacemaker

(Class I Recommendation; Level of Evidence C)
