>>>>>Indicates a faster than normal heart rate. Can be related to some anxiety with taking a test, etc. and not considered abnormal. Requires further information with other tests and symptoms for a decisive dx. Somewhat inconsistent with ventricle contraction rate of 73 bpm!?
Q.Left atrial enlargement.
>>>>An EKG is not a very good source to diagnose chamber and heart wall dimensions. Requires an echocardiogram to view and measure walls and chamber size. If enlarged there can be a number of different causes. The valve opening may narrower than normal, increase intra-pressure of the left ventricle etc.
Right axis deviation is seen on the ECG when more electrical forces are moving to the right than normal. This is usually due to hypertrophy of the right ventricle. Causes of right axis deviation include respiratory disorders such as pulmonary hypertension, etc.
Q. Right bundle block
There are impulses that have pathways (bundle branch) in the heart walls. When a pathway is RBB the contraction of the right ventricle there may be a delay.
The above information is the worst case scenario, and an EKG is not a very reliable source and requires further evidence to make a diagnosis. It is preliminary and helps the doctor to focus on possibilities that need to be ruled out. Thanks for sharing and if you have any further questions or comments you are welcome to respond. Take care and don't be overly concerned.
Usually RBBB whenever said, it is implied as an incomplete block so often it is of no medical concern and conduction is still occurring, but your doctor can better answer that question based on your symptoms, prior tests, concomitant health, etc.
I rec'd your PM, and I hope this answers your question and if you have any other questions you are welcome to reply.
Yes, the described condition of enlargement and abnormality would be the same. A left atrial enlargement is not in itself a problem, but when it enlarges it is compensating to help maintain a balanced of blood flow between the right and left side of the heart, The underlying cause should be treated if considered of medical significance, As stated in my previous post the cause can be narrowed mitral valve, chamber pressures, left ventrical wall stiffness (effects filling capacity), there can be heart muscle disease, etc. Worst case scenarios.
