What are the ECG changes associated with angina pectoris with possible MI?
ECG changes associated with myocardial ischemia include horizontal or down-sloping ST-segment depression or elevation [≥ 1mm (0,1mV) for ≥ 60-80ms after the end of the QRS complex], especially when these changes are accompanied by chest pain suggestive of angina, they occur at a low workload during the early stages of …
What is the difference between Nstemi and unstable angina?
The distinguishing feature between unstable angina and non-STEMI is the presence of elevated cardiac markers, such as troponin, which implies myocardial damage. Patient history alone is insufficient to make a diagnosis of acute coronary syndrome.
Can heart attack symptoms last for several hours?
Timing/duration: Heart attack pain can be intermittent or continuous. Heart attack symptoms can last for a few minutes to a few hours. If you have had chest pain continuously for several days, weeks or months, then it is unlikely to be caused by a heart attack.

- Electrocardiogram (ECG). This first test done to diagnose a heart attack records electrical signals as they travel through your heart.
- Blood tests. Certain heart proteins slowly leak into your blood after heart damage from a heart attack.
What are the ECG changes in MI?
In a myocardial infarction transmural ischemia develops. In the first hours and days after the onset of a myocardial infarction, several changes can be observed on the ECG. First, large peaked T waves (or hyperacute T waves), then ST elevation, then negative T waves and finally pathologic Q waves develop.
What indicates MI on ECG?
The ECG findings of an acute anterior myocardial infarction wall include: ST segment elevation in the anterior leads (V3 and V4) at the J point and sometimes in the septal or lateral leads, depending on the extent of the MI. This ST segment elevation is concave downward and frequently overwhelms the T wave.
How is a Nstemi diagnosed?
NSTEMI heart attacks are diagnosed through the combination of a blood test and an electrocardiogram (ECG). Doctors use the blood test to look for indications of NSTEMI, such as higher than usual levels of creatine kinase-myocardial band (CK-MB), troponin I, and troponin T.
What is an Nstemi mi?
Non-ST-elevation myocardial infarction (NSTEMI) is a type of [“heart attack”: link to new heart attack copy] involving partial blockage of one of the coronary arteries, causing reduced flow of oxygen-rich blood to the heart muscle.
What does cardiac arm pain feel like?
The discomfort may feel like heaviness, fullness, squeezing, or pain. Discomfort in the upper body parts such as the arms, back, neck, jaw, or stomach. This may feel like pain or general discomfort.
Are there warning signs weeks before a heart attack?

Can chest and arm pain be a sign of a heart attack?
Chest pain by itself is the most well-known symptom of a heart attack, but it can also be a symptom of conditions unrelated to your heart, such as respiratory problems, stomach acid reflux, or a muscle strain. If you have chest and arm pain at the same time, however, the odds of it being a cardiac problem increase.
When should I see a doctor about chest and arm pain?
If you experience a brief episode of chest and arm pain and have no other symptoms, you should still see a doctor soon. You may have undiagnosed angina or another condition that should be evaluated. If you have the following previously diagnosed conditions, you should also see a doctor:

What are the symptoms of pinpoint chest discomfort?
Pinpoint chest discomfort that worsens with positional changes in breathing. Heart pain is usually diffuse, or radiating. Pinpoint discomfort that worsens with chest expansion (breathing, for instance) is more likely to involve the lungs. Chest discomfort that gets better with exercise.
