27 years old ekg found that i have a right ventricular conduction delay . is that dangerous and can it lead to a heart attack ?

ECG/EKG: It may be a normal variant for you though structural heart disease is not excluded;follow up with the electrocardiographer given the described symptoms

See cardiologist: Would return to discuss results with provider who ordered ECG. Likely, evaluation by cardiac heart rhythm specialist & echocardiogram is needed to ensure no less common, but more dangerous underlying conditions exist. It's likely normal for you, but genetic conditions, structural problems, & causes of "arrythmias" are possible. Call 911 if dizzy, breathless, chest pain, or pass out.
