and
Elevated & depressed ST segments?

Answer 2

Myocardial infarction or a heart attack can cause some of the changes that you are mentioning. The ST segments elevations and depressions are usually indicative of this. The height of elevation and the lead that it is in can determine the site of the infarction and possibly the age. Depressed ST segments can mean that somebody had a previous MI too.
Cardiac enzymes are important in diagnosing damage to the heart along with the EKG.

Invert T waves could be indicative of a bundle branch block depending on what lead it appears in.

Answer 3

It means an Ectopic heartbeat which is perfectly normal
if up to but not more than 4 bpm. Ectopic is a missed heart-
beat normally caused either by the failure of an electric impulse
or right atrium failure that did not fill the ventricular cavity which
started to beat but skipped it for the lack of blood in the cavity.
I have 35% of ectopic beats on left atrium which amounts to
43.000 beats in a 24 hour period and is controlled by drugs,
which brings it down to the 4 bpm level. If the drugs did not
work, this would mean a pacemaker. I only hope that you are
on the low side of the count and are consulting a Cardiac
Ritmologist since this is a difficult cause to deal with. Good
luck and do not worry, unless you are on high levels, but then
a Cardiologist will take care of the problem. I am 69 and have had
this all life long, and was a top National athlete in various types
of heavy sport and later in lesser stressing sport.

Answer 4

ST elevation is usually indicitive of acute MI. St deppression is seen in old mis and other chronic cardiac disease. we see inverted T waves with alot of our cocaine users also!

Answer 5

I dont know but the other day i saw a bunny with a pancake on its head. :)
