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

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 is st elevation myocardial infarction?

What is st elevation myocardial infarction?

ST elevation...: Many believe that an st elevation myocardial infarction means that it is a transmural infarct (involving the whole thickness of the myocardium). Some people refer to nstemi (non st elevation myocardial infarction) as non-transmural infarct (not involving the whole thickness of the myocardium). These definitions are somewhat debatable but thought you may be interested. ...Read more

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

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

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

Myocardial. Medium perfusion defect moderate intensity in basal mid inferior basal inferior partial reversibility. Ef54%. TID .97 abnormal redegenson.

Myocardial. Medium perfusion defect moderate intensity in basal mid inferior basal inferior partial reversibility. Ef54%. TID .97 abnormal redegenson.

Abnormal stress test: A "myocardial perfusion defect with reversibility" indicates that there is something reducing the blood supply to the heart muscle. Most commonly this would be because of atherosclerosis causing a blockage in the coronary artery. The next steps depend on the medical details. Additional testing, such as a catheter angiogram, may be needed. ...Read more

1 mm st depression in inferior leads. Positive stress ecg. Ischemia involved in the anterior wall and apex. Perfusion defect.?

1 mm st depression in inferior leads. Positive stress ecg.  Ischemia involved in the anterior wall and apex.  Perfusion defect.?

Unhappy heart: The anterior, posterior or inferior all come together at the tip-apex. Septal and usually the -tip of the heart is not getting adequate coronary blood flow. Usually left anterior descending artery blockage. Septal is the inner wall of muscle between the ventricles. Likely will need angio and definitive recommendations. ...Read more

EKG came back High Risk Operation.ST Elevation, consider early repolarization, pericarditis or injury. ST&T wave abnormal consider anterior ischemia?

Need further workup: Need to get evaluated for ischemic heart disease myocardial perfusion scan if done and called for this ischemia ,need to further evaluate with cardiac catheterization and or CTA of coronary vessels to clarify the abnormality especially if you are going for a surgical procedure ...Read more

ABNORMAL MYOCARDIAL PERFUSION STUDY: SMALL SIZED REVERSIBLE PERFUSION DEFECT INVOLVING APICAL INFEROLATERAL SEGMENT AND APEX OF LEFT VENTRICLE?

Arterial blockage.: Ischemia in areas of the heart, as you have related, infers that the arteries that feed these parts of the heart are narrowed such that blood flow through them reduces with exertion. It means these areas of the heart are vulnerable and further testing is needed and intervention may be necessary. ...Read more

What is acute coronary syndrome myocardial infarction?

What is acute coronary syndrome myocardial infarction?

Continuum: Both are a result of inadequate blood supply to the heart muscle. Acute coronary syndrome means that the imbalance is sufficient to cause symptoms that prompt aggressive intervention, but may not result in permanent heart damage; a myocardial infarction implies that overt heart damage has occurred, hence positive markers of tissue damage. ...Read more

What is an unrecognized non-q-wave myocardial infarction?

What is an unrecognized non-q-wave myocardial infarction?

Q vs. non-Q: When a heat attack causes a full thickness ("transmural") heart attack, the ekg reveals the resulting scar by inscribing a "q" wave in the leads that correspond to the damaged area. If the heart attack was not transmural or occurred in an area not seen well on ekg, there may be no q waves. If you had no symptoms at the time of the heart attack (25-50% of all attacks), it will be "unrecognized.". ...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

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
