User :   My husband is 50 years old and overweight. I recently had him undergo a LifeLine Screening in our town. His heart rate and cholesterol were good, however, the section on atrial fibrillation indicated st segment changes. I don't know what this means. His EKG was as follows: Vent Rate: 66
RR Rate: 897
PR Rate: 176
QRS Duration: 98
QT Interval: 400
QTc Interval: 410
QT Dispersion: 40
P-R-T Axis 9-21 151
How serious is this?
Doctor :   Hi
Doctor :   Dr XXXXX here
Doctor :   Let me read your query
Doctor :   Is there any history of chest pain, breathlessness
User :   I don't believe so.
Doctor :   Any family history of such problem?
User :   His father had a quintuple bypass two years ago.
Doctor :   ECG changes are not so accurate and has to be clinically correlated with the clinical features.
Doctor :   Does he have high blood pressure, cholesterol or raised blood sugar?
Doctor :   Is there any swelling in legs, face etec
User :   BP is good. He controls his cholesterol with meds but it's good. He was told he is pre-diabetic. He has been on a low fat/calorie diet for the past three weeks and is losing weight.
User :   No swelling
Doctor :   Did you get a Two D echo done during screening, if yes do you have their findings?
User :   No
Doctor :   What was the oral opinion of your treating doctor with no symptoms and current ECG findings?
Doctor :   Is he currently on any medication?
User :   He hasn't seen his treating doctor yet. I got the results this evening. He takes cholesterol med and flomax.
Doctor :   Does he have prostrate enlargement?
Doctor :   Ok, Let me answer your question after all the information yoiu gave me
User :   He told me the doctor put him on Flomax as a preventative and that he doesn't have an enlarged prostate.
Doctor :   I am not too worried aboiut the ECG readings per se
Doctor :   However ECG readings are always commented along with the previous ECG report
Doctor :   So the next step I suggest you to see the treating Doctor and get a cardiac examination with Stethescope,
Doctor :   If anything significant, he may ask for a 2 D Echo cardiography
Doctor :   Otherwise it is just a finding within the current limits
User :   Thank you. I really appreciate it. This gives me a starting point.
Doctor :   I am only bother
Doctor :   about the raised heart rate
User :   What is a normal rate?
Doctor :   Hi are you back?
User :   Sorry, it timed out.
Doctor :   In atrial fibrillation heart rate up to 150 is normal
User :   His was 151? The vent rate of 66 is circled on the report. Is this cause for concern?
Doctor :   I think 151 is ok
Doctor :   Ventricular rate alone cannot suggest something.
Doctor :   Get a complete examination done along with echo which will help to rule out the exact cause
User :   I will set up an appointment right away. He is not one to tell me if there is anything wrong and he hates to go to the doctor. Thank you so much for your help.
Doctor :   Yes you should get him examined
Doctor :   Is there anything else i can help you with?
User :   Should the appointment be made urgently?
User :   It think that is all. Thank you.
Doctor :   It better to take it soon, but not an emergency.
Doctor :   Thanks for consulting me, bye for now
