Clinical Presentation & Protocol
Patient Usually Complains Of
Patient presents for evaluation of an incidental finding of prolonged PR interval on ECG. Patient denies palpitations, syncope, presyncope, or chest pain. No history of recent viral illness, electrolyte disturbances, or medication changes (specifically beta-blockers, calcium channel blockers, or digoxin).
Clinical Examination Findings
Cardiovascular exam reveals regular rate and rhythm. S1 and S2 are normal; no murmurs, rubs, or gallops detected. Peripheral pulses are 2+ and symmetric. No jugular venous distention or peripheral edema noted. Neurological exam is non-focal.
Treatment Protocol
First-degree AV block is typically benign and asymptomatic; no acute intervention is required. Review current medication list to identify and potentially adjust AV nodal blocking agents. Continue routine cardiac monitoring and follow-up ECG as clinically indicated.
