My stress test results showed that a sizable fixed region of diminished perfusion involving the inferior wall of the ventricle extending to the apex as well as a smaller less conspicuous focus of diminished perfusion involving the anterior wall of the left ventricle. What does this mean? Thanks

There two ways there can be arrythmia.  There is the system's natural pacemaker that is within the right atrium and the impulses travel down the system by electrical pathways in the septum and then move off into the right and left ventricle and contract both ventricles at the same time.  The system's pacemaker is the sinus rhythm.  As an example  abnormal sinus arrhythmia can be a faster or slower than normal heart rate. The source of the rhythm disorder would be due to the natural pacemaker.  If serious the theapy could be a pacemaker implanted in the chest.

There is the way for an irregular rhythm when the sinus rhythm is functioning properly and that is to pick up a stray impulse within the septum and/or heart chambers to cause an arryrthmia.

Without more information it appears your sinus node is producing a good regular heartrate, but an incomplete partial RBBB amy be cause some irregular heart rate and/or occasionally one ventricle is contracting before the other ventricle....not a serious condition but possibly can progress.

Thanks for your response,  Take care.

Thanks for the information, I feel more at ease now. I do have another question,My stress test revealed a sinus rhytem with incomplete right bundle block, what does that mean? Thanks Skidogg

>>>>>>Scar tissue from a previous heart attack may be an issue if the stress test shows
ischemia (lack of blood flow) of the subject area if the perfusion exists for both stress mode and rest.  This would indicate necrotic heart cells as the dead tissue would not function with or without stress.  If your ejection fraction (normal 50 to 70%) is within the normal range you probably don't have any damaged heart cells.  EF is the amount of blood pumped with each heartbeat.

You should have an echocardiogram to determine if there is heart wall movement impairment.  If the test shows a a low EF, it can be assumed the heart cells are necrotic or functioning with a low supply of oxygen (hibernating).  If the cells are dead, a cath would not be of any help.  If the cells are hibernating due to low blood flow to the area, medication can increase the blood flow to the area....angina with stress and rest normal blood flow.

Your symptoms, if any, would be the issue to correct.  If you are having chest pain (angina) with exertion and rest relieves the chest pain that would be stable angina and medication can be effective.  If you are having angina at rest as well as exertion that would be unstable angina, that condition may require intervention such as angioplasty (stent) or bypass.  

Hope this helps and if you have any further questions or comments you are welcome to respond.  Thanks for the question, take care.

It is basically saying that at the back of the left ventricle there is a large section of heart muscle with less oxygen than the rest. This goes all the way down to the bottom of the heart. The front of the left ventricle has a small part that is also receiving less oxygen. Diminished means less or smaller, so unless they've used the wrong terminology, I would suspect the heart muscle is alive but not receiving enough oxygen for exertion. If that amount was scar tissue, I would suspect you would be experiencing all kinds of serious health issues.
At a guess, due to the back being low in oxygen, I would suspect the circumflex artery has considerable disease and/or one of the diagonals from this vessel.
The front of the ventricle is likely to be a small/medium lesion in the Left anterior descending and/or one of the diagonals.
Here is a simple image to show you the arteries.....

I assume they will want to perform an angiogram to verify these results and consider the available options.

Have you had a heart attack?

I may be wrong but It seems that certain areas of you cardiac muscle has an scare due to it.
