Dear friend, welcome and thanks for entrusting your query here at Healthcaremagic!
I am Dr. Prasad Akole (Critical Care Expert- http://bit.ly/Dr-Prasad-Akole) and am glad to address to your query here.
You do have a symptomatic bradycardia with escape
extrasystoles (PACs) as well as dyslipidaemia.
Chest pain, dizziness, passing out is due to
severe bradycardia and resultant
low cardiac output.
If holter shows a severe sinus brady to 20/min or other brady-arrhythmias, and if this has been the age of 16, you have to be fully evaluated.
I would recommend a good comprehensive physical including auscultation for abnormal
heart sounds.
A 2D echo should be done to look for any structural heart disease/ anomaly.
A conduction system defect should be thought of. May need EPS (electro-physiological studies) of the heart.
Rule out electrolyte disturbances (less likely) and
congenital disorders.
Need to do a full
lipid profile and treat the abnormal ones accordingly. You need consultation with a good cardiologist and a physician.
Lie flat when you get dizzy.
Do not neglect this. It can be dangerous.
I hope to have answered your query satisfactorily. I would be glad to answer any further queries. Please ask for any clarifications before closing and rating this query.
Take care and please keep me informed of your progress at http://bit.ly/Dr-Prasad-Akole
Good Luck! Thank you!!
