Extrasystoles - negative T waves

Hello,

I did an heart exam (electrocardiogram) last summer, I didn't understand what was written on paper, I just know that I have extrasystoles and that I have to lose weight.

Now, after the 2nd exam from 3 days ago, I would like to know: what does negative T waves mean in v1-v3? Is this related to extrasystoles?

(I tried to find understandable information on the internet but without success)

Thank you in advance

(it's a post Translated from french to English, so sorry if there are mistakes)

PVC's are quite common and most of us have experienced them.

Negative T waves can be benign as mine are. Most babies are born with it but some retain them into adulthood.

If your T wave was positive in your base ECG and suddenly becomes negative then it could be a problem.

If the T wave changes shape with every beat then it is called T wave alternans. This can lead to dangerous ventricular fibrillation.

I also have T wave inversions they are in my case a sign of a lack of blood supply to my heart

I suggest you discuss this issue with your GP or Cardiologist.

I take it that you have angina pains and need stents to improve blood flow to the heart?

I have never heard of negative T waves to be an indicator of CAD.

I have lived with coronary vasospastic angina for 8 years.

I have temporary constrictions of my coronary microvessels and coronary arteries leading to a lack of blood supply to my heart - myocardial ischaemia and angina.

I have clear coronary arteries

Non obstructive coronary heart disease ( NOCAD) or ischaemia no obstructed coronary arteries ( INOCA)

T wave inversions are a sign in some cases of myocardial ischaemia and need appropriate investigation to determine the cause. I have recorded episodes of ST depressions and ST elevations.

Unfortunately Vasospastic and microvascular angina are poorly recognised and understood, often overlooked as a cause of angina.

There are quite a few members of the forum who live with either microvascular and or vasospastic angina.

My Ejection Fraction is normal and I have had an angiogram, ultrasound, CAT scan and 2 MRI scans of the heart with contrast injection and nothing abnormal was found.

My ST's have always been normal.

My negative T wave was first recorded over 20 years ago.

Negative T waves with ST segment depression (below baseline) is normally ongoing ischaemia. ST in this case represents the ischaemia and not the negative T wave.

Isolated T wave inversions are not acute nor more alarming than normal T waves.
