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.

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.

What is the significance of a non Q wave heart attack?

What is the significance of a non Q wave heart attack?

EKG finding: A q wave is a finding on the electrocardiogram seen after a completed myocardial infarction (heart attack). In some patients with heart attack, the electrocardiogram will demonstrated q-wave. In other patients, a q wave will not develop. In general, q wave myocardial infarctions are larger and associated with st elevation in the early phase of the heart attack.

What is a Q wave in old heart attack?

What is a Q wave in old heart attack?

Part of EKG: Q r s t u waves are parts of the electrical imprint. Q waves in particular locations or size come about due to heart damage and electrical shifts.

Does Q wave always mean you had a heart attack?

Does Q wave always mean you had a heart attack?

Ecg: Q waves mean either electrical force going away from the lead axis being examined or lack of force in the direction of the lead. This is often due to heart muscle damage but not always.

What is the difference between a q-wave and non-qwave heart attack?

What is the difference between a q-wave and non-qwave heart attack?

Wall Thickness: Q wave= full thickness myocardial necrosis non q wave= partial thickness or subendocardial necrosis subendocardial infarcts more common. Full thickness can result in myocardial rupture or an acute ventricular septal defect. Rupture- tamponade-death sequence. 50% of people still die on their first heart attack mostly because of not calling 911 or reaching er within minutes of the infarct.

Would an old heart attack show up on an ecg? If so which wave would show it?

Would an old heart attack show up on an ecg? If so which wave would show it?

Q wave: There are patterns in old heart attack waves on ekg. Often several specific leads will show the scar on particular, specific walls of the heart. Review this with your doctor.

Does inverted P waves automatically mean, you have had a heart attack or have heart disease.

Does inverted P waves automatically mean, you have had a heart attack or have heart disease.

Abnormal: Several causes, but need evaluation of damage or enlarged chambers.

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.

Does poor r wave progressive and nonspecific st&t adnormal waves mean you had a heart attack. The findings were from a nuclear stress test.

Does poor r  wave progressive and nonspecific st&t adnormal waves mean you had a heart attack.  The findings were from a nuclear stress test.

Poor R wave: Poor r wave progression could be seen in old anterior myocardial infarction (old heart attack), in lead misplacement of precordial leads by inexperienced ekg technician, also can be seen pulmonary diseases, WPW syndrome, and dextrocardia. Dextrocardia is very rare. Wpw will be seen in much young age. If you have old heart attack you should see it in nuclear stress test.

My t waves in my EKG were upside down in one part. But the rest of it looked fine, does that mean heart attack?

My t waves in my EKG were upside down in one part. But the rest of it looked fine, does that mean heart attack?

T and sympathy: T waves alone do not mean heart attack. You need to see the whole ECG. T waves absent other abnormalities are quite nonspecific.

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.

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!!

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.

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
