Question 1

is there a link between lbbb and hypertrophic cardiomyopathy?

Accepted Answer

Not neccessarily: A hypertrophic cardiomyopathy may not involve a LBBB but the cardiomyopathic process can cause interventricular conduction delay and this could manifest as a lbbb.

Question 2

dx ist 2005;put on toprol; diagnosis 2014  lbbb now with decreased ef; could beta blocker have caused lbbb and now non ischemic cardiomyopathy? i feel it may

Accepted Answer

LBBB/Cardiomyopathy: The devil is in the details;LBBB in its own right can cause a reduction in ejection fraction,vice versa can also occur.Cardiomyopathy with reduced EF is best treated with betablockers,Please consult in detail with a competent cardiologist

Question 3

could i have cardiomyopathy with no other symptoms but an lbbb on my ekg? i have an appt w/ a cardiologist in a few days, but i'm nervous from reading

Accepted Answer

ECG : Left bundle does not necessarily mean there is significant pathology present. Don't get nervous, your cardiologist will evaluate for you.

Question 4

lbbb, pre excitation, shortness of breath, exercise intolerance, can't do daily activities, extreme fatigue, chest pain. restrictive cardiomyopathy?

Accepted Answer

Chest pain,fatigue,: Various cardiomyopathic states can cause your symptom complex ,what does your Echo cardiogram reveal? LBBB and pre excitation can compound the reported symptoms;please consult with a cardiologist with an interest in these areas

Question 5

can lbbb be reverted?

Accepted Answer

Often permanent: I have only seen it once in a patient who developed LBBB with a viral infection/myocarditis and several weeks following resolution of the illness, the LBBB also resolved. Otherwise, al other cases so far have been "permanent finding." it is not a dangerous thing, just a bit difficult to interpret when you are actively having issues with your heart such as a heart attack. Worry not anita. Good luck.

Question 6

bp great, lbbb diagnosed, cath was excellent w/slightly elevated edp, no dyastolic dys. what causes it if all else is perfect? is caffeine bad for it?

Accepted Answer

LBBB: you appear to have LBBB due to 'we don't know what but your heart is ok anyway '. Caffeine in moderation should be ok. Follow good health practices,diet,exercise don't smoke. A list of possible causes of LBBB won't fit in this space

Question 7

can lbbb be seen on a stress test?

Accepted Answer

Yes it could be: And it could be investigated further also.

Question 8

my concern,knowing bp 119/68 (avg),ef 55%, mildly elevated edp/20-25mm, lbbb, plumbing great, no pain but sob w/exertion should i still exercise? all started in the past few years, am i deteriorating

Accepted Answer

Yes you should: Exercise or you will deteriorate and your heart muscle will weaken. Exercise is important. Start slow and increase as tolerated

Question 9

can a person have a normal ekg and have lbbb ?

Accepted Answer

No: Left bundle branch block is an abnormality that could make ekg interpretation difficult.

Question 10

61yr.fem.w/lbbb-take 12.5/am, 12.5/pm metoprolol tar.  can i up to 25/am,25/pm for stress of 8 day trip to ireland, or as/if needed, temporarily?

Accepted Answer

You have not said: what you take the Metoprolol for. Your current dose is very small but it is not for stress it is for cardiac or vascular reasons. LBBB will not affect the consideration for dosage adjustment. Your blood pressure and heart rate are bigger considerations. You need to check with your prescriber to determine why you are on low dose and if it is safe for YOU. Without knowing your medical history, No.
