left atrial compression?

Question

Ive been short of breath for like 2 years and ive been getting light headed, ive some dull achy pain occasionaly that last like 2-3 min. and i did a whole bunch of test and everything was normal except my heart monitor showed my resting heart rate at 114 and the highest it got was 158 ( and that was with very very minimul activity, i only went to the store with my mom) and then i had an echo done today and the tech. couldnt tell me anything because my doc. is suppost to but this is what he wrote under comment. ejection fraction 55%, tachycardia with irregularity and possible left atrial compression, can anyone tell me what that acctual means? thank you :)

also im 18, dont smoke or do drugs im not over weight and i dont have high blood pressure. Also, the tech who did the echo asked me if i knew anyone with diabetes. oh, and last night my left arm from my shoulder to my elbow went tingly and sort of numb.

Answer 1

I sorry to say but you will have to go a thorough investigation such as CT scan to find out the cause of compression, which are as follows.
Extrinsic left atrial compression is an uncommon source of hemodynamic compromise that can be caused by many mediastinal structures, including bronchogenic cysts , carcinoma , lymphoma , thymoma , aortic aneurysm , and diaphragmatic hernia . To date, however, few cases of gastric structures (stomach, esophagus, or both) causing hemodynamically significant left atrial compression have been reported . We describe three cases of extrinsic left atrial compression by the stomach that caused simultaneous hypotension and congestive heart failure.
You will have to stay tuned with your physician till a final diagnosis is reached.
Get well soon.

Answer 2

Normal resting heart rate is between 60-90, Your way to fast.
Ejection fraction: 55 out of 100...way low for somebody so young

tachycardia with irregualrity ...probably translates to Sinus tachycardia with irregular beats to resperation effects or PVC's

Chest pressure, arm numbness sounds like angina pectoalis a sign of a cardiac problem and heart ischemia.

Call your doctor...demand a consult....if necessary get a second opinion. Heart problems are rare in kids and can be overlooked by those who dont wanna see them or are lazy.
