Can smoking marijuana have bad effects for a left bundle branch block?

Maybe yes. Among the bad things smoking marijuana does to the heart and lungs are the quick rise in heart rate and blood pressure, the increased demand for oxygen by the contracting heart muscle, followed by vasodilation (blood vessels relax and dilate) with a drop in blood pressure as smoking mj continues; the abnormal rhythms in the upper heart, and maybe abnormal ventricular (lower heart) rhythms.
Yes . Lbbb is the result of vascular compromise to the heart's conduction mechanism, acute or chronic. As such any agent that decreases blood flow like cannabis, will worsen an already compromised heart. Please stop mj now before your lbbb gets worse.

What occurs when someone has a left bundle branch block?

Nothing to severe. Left bundle branch block (lbbb) is a pattern on the ECG that indicates that the heart's electrical waves are following an unusual path. It is common in older age, and usually due to scarring of the pathway. It may cause no symptoms and need no therapy. It can lead to marked slowing that needs a pacemaker. A new lbbb can also be a sign of a heart attack. Read more...

I hear my heartbeat in my head. I just find out I have a left bundle branch block. Had a heart cat everything fine. Why do I hear this sometimes?

Rule out murmue. some forms of heart murmurs could cause the symptoms you are describing and can be detected on an echocardiogram which you've likely had. This could also be a form of tinnitus that can be evaluated by an ENT. Hope it goes away. Read more...

Can chemotherapy cause left bundle branch block?

Sometimes. A left bundle branch block is a finding on an EKG ( the electrical tracing of your heart.) it shows that something has altered the way your heart conducts electrical impulses. Chemotherapy can do it, but so can heart disease. Your doctor should rule out other causes for a left bundle branch block before assuming chemotherapy is the cause. Read more...
Chemo. Many chemotherapies can cause heart problems (ie, adriamycin (doxorubicin) - heart muscle problems; Paclitaxel - very fast heart rate or arrhythmia). Lbbb is not a common side effect but it is possible. Read more...

Is heart block the same as rate related left bundle branch block?

Heart block and LBBB. Left bundle branch block is a form of arrhythmia or "heart block" as you mentioned. "heart block" would refer to all rhythm abnormalities, whereas left bundle branch block is a more specific type of arrhythmia. Read more...
Not the same. Both are types of fatigue in the heart's wiring system. 1st degree heart block is when there is a delay in the signal getting from atria down to ventricles. That's minor. In more advanced heart block, some beats dont get through at all. In lbbb, there is no block between atria + ventricles but there is a delay in the signal spreading within the ventricles, which doesnt cause symptoms by itself. Read more...

I am 21, what can left bundle branch block mean on my EKG? It shows up whether my HR is normal or fast

Rate related delay. You have a "rate related LBBB" meaning that as your heart speeds up, the conduction through the His-Purkinje network of fibers (conducting tissue in the heart muscle) take a longer time than normal to repolarize (prepare electrically for the next impulse). As I said in my previous post to you, trust your EP doctor. Read more...
