Requires follow up: Lbbb is an unusual finding in a normal heart, and requires further testing and follow up. At the very least, you should undergo an echocardiogram. If normal, it should be repeated every 5 years or so. An exercise stress test and a 24 hour holter monitor may also be appropriate, but are not mandatory. You should see a cardiologist. ...Read more

Electrocardiogram (Definition)

Electrocardiogram (ecg, ekg) is a print-out of the electrical forces detected by electrodes on the chest wall, as electricity travels through the heart with each heart beat. The electrodes are placed in different positions, and each position "sees" the electrical activity of the heart from its own vantage point. Abnormalities in signal detected at chest surface ...Read more

Maybe: The finding of lbbb on an ECG can be seen in cardiomyopathy, myocarditis, ischemic heart disease, left ventricular hypertrophy, and several other conditions. It can occasionally be present in a normal heart. Most people with cardiomyopathy have symptoms as well. Keep your appointment with your cardiologist. ...Read more

Ekg results; vent 81bpm, p duration 122, qrs duration 138, pr interval 178, qt/qtc 392/428?  How abnormal is this?  Only diagnosis I have is lbbb.

Depends: Lbbb is abnormal. It may be associated with coronary heart disease, high blood pressure, an enlarged heart, or cardiomyopathy (heart muscle disease). Rarely, it can be congenital (present at birth). The significance of lbbb depends on the presence or absence of associated heart disease and whether it is a new finding or has been present for several years. May need echocardiogram and/or heart cath. ...Read more

EKG says LBBB & escape rhythm? Transplant specialist says my heart pumps inefficiently. What do the LBBB & escape rhythm mean?

See Below: LBBB= Left Bundle Branch Block. This means that the normal conduction system of your heart is not functioning properly. Not to worry, your heart has other ways to conduct electricity. Escape rhythm means that because the conduction system isn't working right, your ventricles are controlling the electricity to make your heart conduct and contract. ...Read more

My dad (66) has LBBB since 4 yrs ago on several ekg's. His mom had CAD. Cardiologist did lots of test 2 times, found nothing. Cause? Is it fatal?

My dad (66) has LBBB since 4 yrs ago on several ekg's. His mom had CAD.  Cardiologist did lots of test 2 times, found nothing. Cause? Is it fatal?

Maybe, maybe not: There're quite a few causes of LBBB. Aortic stenosis, dilated cardiomyopathy, acute heart attack, coronary artery disease, disease of the cardiac electrical conduction system, long standing untreated hypertension, lyme disease etc...even some viral infections can cause this. Since his testing=negative, he is NOT more likely to die than other men his age. Regular follow up is advisable. Good luck! ...Read more

My EKG now reads escape rhythm, LBBB, & intraventricular conduction delay. What does this indicate? I was started on digoxin to hold me up for a week

Complicated: Since you had an ablation, you're obviously under the care of electrophysiologist, so you should trust their judgement. You have a complicated situation. Your rhythm isn't textbook normal but may be fine for you. If you're not feeling well now (you mention dizziness in particular), please contact your EP right away. ...Read more
