Question 1

what does t wave inversion mean in lead iii and avf?

Accepted Answer

Depends: In a vacuum, it's a non-specific finding. Isolated T inversion in III is common and normal but when combined with aVf, it can sometimes mean that the inferior wall of the heart isn't receiving adequate circulation. Further testing is indicated.

Question 2

inverted t wave in lead 3. normal chemistry/cbc. next day t-waves were normal (upwards) causes for this?

Accepted Answer

Questionable: Inverted t waves in any one lead are of rather questionable value.  If you do not have any symptoms such as chest pains, sob, sweating without a reason, nausea or vomiting, i would not worry about it too much.

Question 3

can incorrect lead placement lead to an inverted t-wave on ekg?

Accepted Answer

Yes: Yes, absolutely.  Avr usually has inverted t-waves normally.  If you invert left and right arm electrodes, avr becomes avl so now avl has inverted t waves (where as typically it does not).

Question 4

can you, please, explain why is it, that st elevation in lead iii greater than the one in lead ii is suggestive of mi?

Accepted Answer

ECG: ST elevation is a vector representation of electrical force. The lead 3 direction usually has less muscle mass than the lead 2 direction.  There is no firm rule however only a suggestion because of anatomical variations.

Question 5

is there any difference between nonspecific t wave changes and inverted t-wave?

Accepted Answer

Not really: Not really. Those are just two different ways to describe the same abnormality seen in the ekg.

Question 6

does an inverted t wave mean it could be hcm?

Accepted Answer

Twave: Inverted t wave is a very nonspecific finding. Hcm is possible but not probable with only t wave abnormality.

Question 7

what does ecg report saying t wave inversion in iii & avf means.

Accepted Answer

Nonspecific: The t wave is more commonly upright in those leads; when it is upside down (a negative deflection), it is  inverted.

T wave inversion in leads iii and avf can represent normal findings, but in the appropriate clinical setting, can indicate that further evaluation of the heart is needed.

Question 8

inverted t wave in v3 and v4 and irbbb are these the same thing or separate issues?

Accepted Answer

They are: "similar" in that they are" NON-SPECIFIC"..that is NON-DIAGNOSTIC and , in fact, might best be considered NORMAL findings!  NO WORRY NECESSARY!

Hope this is helpful!

Question 9

i have just had an ecg and the reading says i have an inverted t-wave and a deviant axis. i am a 46 year old who does endurance cycling, and want to know if this poses any risk to me? should i go and see a cardiologist?

Accepted Answer

Waves: T he inverted T waves could be significant. HOWEVER THEY ARE OFTEN NON SPECIFIC.I would see a cardiologist as he could do further testing to exclude any problems. Good Luck

Question 10

74 years type 2 dm for past 20 years. last week chest pain while walking alone and got better when taking rest. ecg and echo normal .trop i score 9.2.tmt positive with downsloping st segment and t wave inversion reversed in recovery phase.diagnosis?

Accepted Answer

: It sounds like angina. The person may need a stress test to see what happens with exercise and, if ischemia is present, will need treatment. This person should be seeing a cardiologist. Best of luck to you!
