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

Hoping you can tell me, is right bundle branch block (rbbb) something to really stress over everyday?

Hoping you can tell me, is right bundle branch block (rbbb) something to really stress over everyday?

Not really: Rt bbb is a common ekg finding and it may occur in some medical conditions.But it is also common in some people with normal heart it occurs in conditionsthat effect the right ventricle or the lungs.If you are otherwise healthy and no other symptoms and your doctor gave you clean chit, than you do not need to stress over it every day. ...Read more

Would it be possible that a rbbb (right bundle branch block) cause a heart murmur?

Would it be possible that a rbbb (right bundle branch block) cause a heart murmur?

No: A rbbb is a pattern seen in the ECG where the electrical impulse is delay or interrupted as it spread along the heart. Prevalence increase with age. At 80 y/o close to 10% people can have it. Somewhat benign but an evaluation need to be done to r/o heart and lung conditions. Conditions like copd, cad, myocarditis, valvular heart disease, and other structural heart conditions. ...Read more

Right bundle branch block and Z-pack (Azithromycin) prescribed for infection. Haven't taken yet, any concern for heart issues with RBBB and Azithro?

Right bundle branch block and Z-pack (Azithromycin)  prescribed for infection. Haven't taken yet, any concern for heart issues with RBBB and Azithro?

BBB: ECG QT interval prolongation can be a concern with azithromycin,the bundle block adds to the measured QT interval ,however the more relevant measure is the JT interval that ECG machines don't record/measure,consult locally with the prescribing physician.Also don't delay antibiosis with out the prescriber being aware. ...Read more

I have gone through ECG. it reports right bundle branch block and bifascular block. Is it normal? How can I cure it? What precautions should be taken?

Heart block: you need to see a cardiologist (heart doctor) for further testing (electrophysiology ) Do you have symtoms -- fainting, dizziness ? ...Read more

I am diabetic, age 36. I have lightheadedness problem also. Yesterday I got 'Right Bundle Branch Block' in my ECG report. Is it a serious problem?

I am diabetic, age 36. I have lightheadedness problem also. Yesterday I got 'Right Bundle Branch Block' in my ECG report. Is it a serious problem?

Not really: RBBB typically is not a worrisome finding as it does not correlate with ischemia/CAD as new LBBB does. Having said that, because you are "lightheaded", a holter monitor and resting echo may be warranted to evaluate for any other arrhythmias and for structural heart disease, respectively, if any. Last as u r of South Asian descent, pls be sure to check ur fasting lipids, glucose and don't smoke. ...Read more

Bundle Branch Block (Definition)

There are 2 main branches of the heart's electrical system within the ventricles, the right bundle branch and the left bundle branch. Additionally, the left bundle branch has two sub-branches, the antero-superior fascicle and the posteroinferior fascicle. When one or more branches are disrupted, the resultant electrical abnormalities can be ...Read more
