Are q and t waves inversion on EKG an indication of a past heart attack?

Are q and t waves inversion on EKG an indication of a past heart attack?

Possibly: Abnormal ekg's (ecg's) are one diagnostic criteria for prior heart attacks. However, these changes can also be seen in hypertension, cardiomyopathies, pulmonary disease, and even in normal hearts. ...Read more

Myocardial Infarction (Definition)

Myocardial Infarction means some of the heart muscle dies because of insufficient oxygen supply. Most often this occurs because the coronary artery is blocked by plaque & clot. Other causes include tears in the artery wall, extremely high oxygen demand (eg, rapid arrhythmia, heart valve disorder, or severe systemic illness.) Prompt treatment can minimize heart damage & ...Read more

Do q and t waves inversion on EKG always an indication of a past heart attack?

Do q and t waves inversion on EKG always an indication of a past heart attack?

Common: But not perfect p, q, rs, t u are all ekg waves the total patterns can give us rate rhythm, and some damage information and hypertrophy or enlargement information. Need the whole thing and sometimes echo, and chemical data. ...Read more

I got my ECG results and my Q wave was abnormal. Does this mean that I had a heart attack?

I got my ECG results and my Q wave was abnormal. Does this mean that I had a heart attack?

It depends: It depends on the location and size of the q waves in relation to the other parts of the qrs complex. Ask your doctor to look at the ECG and let you know. ...Read more

27 years old , st and t wave abnormality in ecg, 61 kg, smoking, no family history. What risk for heart attack?

27 years old , st and t wave abnormality in ecg, 61 kg, smoking, no family history.  What risk for heart attack?

Quit Smoking: While ST and T wave abnormalities on ECG may often be nonspecific, smoking causes heart attacks, strokes, amputations of the legs, lung disease and cancer. You're a young man - it's time for you to quit smoking! I can't quit for you but you can! Other than rapidly opening blocked arteries in an acute heart attack the only intervention to save more hearts is quitting smoking!! Do it today!! ...Read more

How does a previous heart attack represent itself on an ecg? Which wave and the form of the wave?

How does a previous heart attack represent itself on an ecg? Which wave and the form of the wave?

Q wave: Many, but not all old heart attacks show up as a q wave which is an initial significant downward deflection but this can also be seen in some normal variants. Reading ecgs can be tricky and significant training is needed to read them well. ...Read more

My dad had a massive heart attack at 60 yrs. Im 19 yrs old and I've found out I have abnormal septal motion, poor R wave on ECG nd 60-65% EF. Causes?

My dad had a massive heart attack at 60 yrs. Im 19 yrs old and I've found out I have abnormal septal motion, poor R wave on ECG nd 60-65% EF. Causes?

Abnormal Echo?: Abnormal septal motion can't be seen on EKG. Did you have an echocardiogram? If so, clarify that they've ruled out a condition called hypertrophic cardiomyopathy(HCM), which is a thickening of the heart muscle. Also clarify the type of "massive heart attack" your Father had, as the status of his condition will determine how hard of an investigation should be done to look for HCM. ...Read more

In my last EKG it stated that there was a "probable anterior infarction". I didn't notice it until going through my records. Is that a heart attack?

In my last EKG it stated that there was a "probable anterior infarction". I didn't notice it until going through my records. Is that a heart attack?

Heart Attack: Possible. There are a lot of false positives on EKG. The only way to truly tell is to see a cardiologist and he can do some additional tests to verify or not. ...Read more

A major heart attack would always show up on EKG ?

A major heart attack would always show up on EKG ?

Not always: For example, with balanced ischemia, the changes in the ekg for one area are balanced by changes in another. But as a general rule, major mi does have significant changes. ...Read more

Is an EKG a good diagnosis tool for heart attack?

Is an EKG a good diagnosis tool for heart attack?

An EKG is ONE tool!: First of all, if you are currently having symptoms of chest pain, chest tightness, shortness of breath, nausea, indigestion, jaw pain or pain in the arms, stop reading and dial 911. An ekg is one piece of information. But certain blood tests look for chemicals produced by injured heart muscle, echocardiograms look for poor heart wall movement, and angiograms look for blockages in vessels. Lgromko. ...Read more

Electrocardiogram (Definition)

Electrocardiogram (ecg, ekg) is a print-out of the electrical forces detected by electrodes on the chest wall, as electricity travels through the heart with each heart beat. The electrodes are placed in different positions, and each position "sees" the electrical activity of the heart from its own vantage point. Abnormalities in signal detected at chest surface ...Read more

Heart Attack (Definition)

A life-threatening condition in which the blood vessels that supply the heart becomes occluded and thus the heart itself is not longer receiving any blood flow. Without this blood flow, the heart muscle dies and cannot pump blood to the ...Read more
