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

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

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

What is a septal myocardial infarction?

What is a septal myocardial infarction?

A heart attack: The septum is the wall that separates the right from the left side of the heart. Myocardial infarction, a heart attack, is caused by a blocked artery in the heart. If the artery blocked supplies the blood to the septum the result is called a septal myocardial infarction. ...Read more

How painful is a myocardial infarction?

Unique to person: In many occations not painfull at all. Most common symptom is chest pressure, heavyness, oppresion, shortness of breath not "pain", sometimes indigestion like symptoms. "silent" heart attacks are common in patients with diabetes. Still today about 50% of people die on their first heart attack. In many occations thinking" its not my heart", " its reflux", "indigestion", "my hiatal hernia"anything but. ...Read more

How do you diagnose myocardial infarction?

How do you diagnose myocardial infarction?

Multiple methods: Myocardial infarction (mi) is suspected by symptoms usually including chest pain. The conclusive diagnosis is established based on a combination of specific abnormalities of the electrocardiogram (ekg) and presence of certain heart enzymes that leak into the blood during an mi. The most common enzymes are called ck-mb and troponin. ...Read more

What factors make myocardial infarction worse?

What factors make myocardial infarction worse?

Many: The location is a major factor: left main blockage is most likely to be fatal. Proximal left anterior descending is also often fatal. Patient factors such as on-going tobacco use, uncontrolled hypertension, diabetes, anemia, pre-existing heart or kidney failure and advanced age all raise the risk. ...Read more

Should is the first step to take if a person has myocardial infarction?

? MI?: 18 year old boys don't have MI's almost ever. If they are feeling chest pain it is almost invariably reflux wherein stomach contents are being regurgitated up the esophagus and it is called heartburn. A key to diagnosing a true MI is that the pain is exercise induced-I.e. It gets worse when you're walking up the stairs or whatever and it gets better when you stop. If that is so, get to ER pronto. ...Read more

How do you prevent myocardial infarction?

Many approaches: There are many type of interventions to prevent heart disease. Eat a diet lower in saturated fats and chiolesterol. Increase your intake of fiber, fruits and vegetables. Start an exercise program, 30 minutes 5 days a week. See a doctor. Check your blood pressure, cholesterol and fasting blood sugar. Talk about family history. Know your risk levels and get started on therapies to modify them. ...Read more

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

What is an inferior myocardial infarction from?

What is an inferior myocardial infarction from?

Many poss causes: An inferior mi refers to a heart attack on the inferior wall of the heart muscle. Almost all heart attacks are the result of fatty deposits on the inside of arteries that break open and cause clotting which will blocks the artery (and the blood from flowing to the part of the heart the artery feeds). Family history, fatty diet, smoking, high blood pressure all contribute to this process. ...Read more

Why is the t-wave inverted in myocardial infarction?

Why is the t-wave inverted in myocardial infarction?

Repolarization: The t wave on the electrocardiogram reflects the pattern of electrical repolarization in the heart. During a myocardial infarction, the pattern of electrical repolarization is reversed resulting in a reversal of the axis of the t wave. ...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

How are angina pectoris and myocardial infarction different?

Continuum: Angina can be quite severe and respond to rest, oxygen, nitroglycerin. And fully recover with no muscle death.

there is heart muscle death as the defining entity
may need surgery or intervention. ...Read more

Is the pain that occurs in angina pectoris and myocardial infarction the same?

Chest pain: Typically the pain of angina pectoris resolves with rest and lasts just a few minutes at most. Heart attack pain typically is a resting pain and is like angina but worse. They are both caused by myocardial ischemia but the angina ischemia is reversible. The heart attack ischemia results in death of some of the heart's muscle. ...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
