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

What happens in the EKG during myocardial infarction? Do you get big earthquake-like tracings?

What happens in the EKG during myocardial infarction? Do you get big earthquake-like tracings?

Variable: This varies depending on the location, severity and type of myocardial infarction. Some patients have no ECG changes at all, known as electrically silent myocardial infarctions, a phenomenon more common in diabetics. Other patients have severe changes in their ECG tracing with severe arrhythmias which can be fatal. ...Read more

Ekg say flat t waves in v4v5v6.Check av block of higher degree. Absolute arrhythmia, atrial flutter.Inferior myocardial infarction, probably old, normal?

It is hard to : Say based on your description, but it sounds abnormal of course, you should see if there is a clinical correlation. Review it with your doctor and compare it with old ekgs. This will help determine the next best step. ...Read more

What occurs in the ECG during myocardial infarction?

What occurs in the ECG during myocardial infarction?

Changes in waveform: Myocardial infarction leads to new findings in ECG such as new "q" waves, st segment elevation and t wave inversions or new bundle branch blocks. ...Read more

Possible inferior myocardial infarction probably old. Possible abnormal ecg...Does this mean i had an attack? I am diabetic and workout daily.

Possible inferior myocardial infarction probably old. Possible abnormal ecg...Does this mean i had an attack? I am diabetic and workout daily.

EKG change: Q waves on an ekg suggest prior damage. If there were symptoms, enzyme elevations helps confirm the timing and degree. Compare with any prior ekg. Continue your risk reduction approach, but discuss with your pcp. ...Read more

Anterolateral myocardial infarction probably old came up on the ecg. My doctor said its nothing to worry about, can I have an easy to understand defin?

Stupid Computer: The computer reads on ekgs are designed to catch as many heart attacks as possible but they are notorious for overcalling heart attacks. A trained cardiologist can sort the matter out using experience, training and a set of rules. ...Read more

Chest pain and possible myocardial infarction. Ecg reveals sinus tachycardia. What does this mean at 50?

Sinus tachycardia: Sinus tachycardia refers to a faster than normal heart rate. Usually higher than 100 beats/minute. Please see your pcp for further evaluation for chest pain. ...Read more

Why is there ST segment elevation during a myocardial infarction?

Why is there ST segment elevation during a myocardial infarction?

Ecg: The ST segment elevation is caused by an electrical potential difference in that phase of the cardiac cycle between the dying cardiac muscle and normal parts of the heart and the vector direction of that potential difference as manifest on the ecg. ...Read more

I need to know what's an inferior myocardial infarction?

I need to know what's an inferior myocardial infarction?

Heart attack: Inferior myocardial infarction is a heart attack on the bottom of the heart. This portion of the heart is frequently served by the right coronary artery but occasionally by the circumflex coronary artery. When the artery closes, the bottom of the heart does not get any blood, and the muscle of the heart is injured. ...Read more

Reason for st segment elevation in myocardial infarction?

Reason for st segment elevation in myocardial infarction?

Electrical: A heart attack damages muscles in the heart. The flow of the electrical current throughout the wall changes when having to go around the damaged muscle, resulting in certain ekg changes, since ekg's show the path of electrical current in the heart. There are different changes, de[ending on which part of the muscle is damaged. ...Read more

Whats the meaning of "st elevation myocardial infarction (stemi)"?

Severe Heart Attack: Heart attacks - the lay term for myocardial infarction - comes in two levels of severity..Non-st-elevation (nstemi) and st-elevation (stemi) which refer to changes on an ekg and broadly reflect if an arterial occlusion is total or subtotal. ...Read more

How high will the ck-mb be elevated if there is a myocardial infarction?

Depends: The elevation of ck-mb is in direct proportion to the size of the infarction. The highest i personally have ever seen was about 1000 but that is very unsual. Also, ck-mb will rise as a % of the total circulating ck. Normall ck-mb is less than 1.5% of total ck. After infarction, ck-mb will go to anywhere between 2.5-15% of total ck. ...Read more

I was wondering is angina pectoris and myocardial infarction the same disease?

I was wondering is angina pectoris and myocardial infarction the same disease?

Not: Angina means your heart isn't receiving enough oxygen to meet its needs. However, it's reversible. Mi means that the deficiency in circulation is so severe and prolonged that there has been irreversible heart damage with cell injury and death. ...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

Infarction (Definition)

When the blood supply of a tissue is compromised by whatever mechanism, the tissue will stop working and if blood flow is not restored, the tissue will eventually die ("infarct", both verb and noun). The clinical picture that runs with development of an infarct ("heart attack"; ...Read more
