What are two characteristic EKG findings of a transmural myocardial infarction?
535823
the two EKG characteristics of a transmural MI are ST elevation with deep Q waves,  followed by T wave inversion

Sounds like WPW sydrome, or atrial fibrilation.  Go to a cardiologist and get an EKG.

It would be very unusual for a 19 y.o. to be having coronary problems.  You say your chest feels tight when you lie down at night.  I wonder if it isn't just chest wall pain from your workouts.  You say you get short of breath when you run, and you develop a pain in your lower left chest then.  I don't know how bad your shortness of breath is.  You can simply be short of breath running, because you are overweight or out of shape.  Chest pain of a heart attack or angina usually presents right in the middle of your chest as a pressure type pain, not off on the left side like you describe.  I would be more concerned about a valvular heart defect, than coronary disease.  Have you ever had a heart murmer?  I'd recommend you go and get a good physical.  He should listen to your heart carefully for any murmur.  He should get a chest xray and a resting EKG.  If there is any question of a murmur, I would get an echocardiogram.  The chest xray as well as the echo, together with the physical exam would make sure you got a normal size heart and no valve abnormalities.  The other thing he might want to get is a treadmill EKG, to see if when you have those symptoms running, there is any change in the EKG to indicate ischemia. You didn't say what your weight was. If you are overweight, I would recommend walking, rather than running, at least until you take off some pounds.

It is used to view the electrical activity in your heart. It makes a map of how electricity flows through your heart.\n\nIt can show if part of your heart is getting too little blood(angina) or no blood (a heart attack or "myocardial infarction (MI)").\n\nIt can also show if one or more of the hearts chambers are enlarged or thickened.\n\nIt is also how abnormal heart rhythms (like atrial fibrillation) are diagnosed.\n\n\nFor how simple and inexpensive it is you get a tremendous amount of very important information.\n\nIt one of my favorite tests.

www.ecglibrary.com hass all kinds of information\n\n-or try searching for ECG or EKG interpretation with any internet search engine, there is a plethora of resources out there\n\n-or go to a library (especially if you have access to a univeristy or medical school library) and find any of a thousand books on the subject

Chest discomfort. Most heart attacks involve discomfort in the center of the chest that lasts for more than a few minutes, or goes away and comes back. The discomfort can feel like uncomfortable pressure, squeezing, fullness, or pain.\n\nDiscomfort in other areas of the upper body. Can include pain or discomfort in one or both arms, the back, neck, jaw, or stomach.\n\nShortness of breath. Often comes along with chest discomfort. But it also can occur before chest discomfort.\n\nOther symptoms. May include breaking out in a cold sweat, nausea, or light-headedness\n\nno hair loss is not a symptom\n\nhan

That's one symptom of a heart attack. You might want to consider going to the ER.\n\nOther signs:\nnausea\nsweating\nheadache\ndizzy feeling\nfainting\n"heart-burn" type feeling\npressure in chest area

that the heart rate goes up fast exercise then at rest comes back quickly to normal is ok.\nthe important thing to look for (after you said the coronaries were ok) is systolic dysfunction,\nthat can be cleared by doing an exercise echocardiogram.\n\nof course age has something to do with it too.

well,myocardial infarction is a serious, sudden heart condition usually characterized by varying degrees of chest pain or discomfort, weakness, sweating, nausea, vomiting, and arrhythmias,sometimes causing loss of consciousness,it occurs when the blood supply to a part of the heart is interrupted,causing death and scarring of the local heart tissue,since the area affected may be large or small,the severity of heart attacks vary,but they are often a life-threatening medical emergency which demand both immediate attention and activation of the emergency medical services.\nso, anteroseptal myocardial infarction  is a type of myocardial infarction (as classified according to the site)in which the infarcted area includes the anterior wall of the heart & the septum (interventricular septum).

Treadmill stress electrocardiography is employed widely to detect underlying cardiovascular disease in asymptomatic persons. To determine the frequency and significance of an abnormal S-T segment response to exercise in young athletes with increased left ventricular (LV) mass induced by physical conditioning, 75 male isometrically trained athletes without evidence of heart disease (mean age 21 years) and 48 nonathletic young normal subjects were studied by M-mode echocardiography and exercise electrocardiography. Ventricular septal and posterior free wall thicknesses and calculated LV mass were significantly greater in athletes than in control subjects. An abnormal S-T segment response to exercise was present in 7 (9%) of the 75 athletes, all of whom had a LV mass greater than 275 g and in 5 the LV mass was above the 95th percentile of that of the control subjects. An abnormal treadmill exercise test result also was present in 3 (6%) of 48 control subjects. Seven of the 10 subjects with abnormal exercise test results had radionuclide angiograms at rest and with exercise, each of which was normal. It is concluded, therefore, that (1) abnormal exercise test results occur commonly in both athletes and non-athletes; (2) almost 10% of isometrically trained athletes have "false-positive" exercise electrocardiograms, suggesting that this test has major limitations in screening for underlying cardiovascular disease in athletes; and (3) in athletes, a relation was present between "physiologically" increased LV mass and false-positive exercise test results.

The term is a "premature ventricular contraction"  (aka PVC).  It is common and benign.  Although it feels like your heart stops, the large part of your heart actually beats earlier than it was supposed to have....then the signal comes through to tell it to beat...but it doesn't beat because it needs to reset after having just beat....then there is a slight pause until the next signal comes down telling it to beat.  It resumes completely normal function thereafter.  If you have many of these episodes or if you become light-headed or dizzy with them, then you should get it checked.  Otherwise it requires no medical attention.

Did you mean brokenheart? If sure, I tell you that syndrome really exists. After any emotional stress, the person, more commonly a woman, develops transient dysfunction of the apical portion of the left ventricle, with compensatory hyperkinesis of the basal walls, producing ballooning of the apex with systole in the absence of significant coronary artery disease. The clinical present is like an acute MI, with ST elevation, but absence on angiography of obstructive coronary artery disease or evidence of acute plaque rupture. Although the severity of acute phase, including a mortality rate of less than 10%, the treatment is supporting and total recovery occurs in the majority of cases.

Left Anterior Descending Artery\n\nCause many times people get heartattacks due to blockage in this artery, and it happens both fast and unexpectedly.

the electrocardiogram is a noninvasive test to aid in the diagnosis and treatment of hearth disease and related conditions a EKG records the hearth electrical activity in a visual graph they are also called stress test.The electrocardiograph is the result of the test in other words a electrocardiograph.

The entire LV wall function is not contracting / relaxing fully to its limit.\n\nWALL MOTION ABNORMALITIES\nNormally the contraction of the heart has a wringing motion, due to the arrangement of cardiac muscle fibers. For global evaluation, 2-D each is a useful tool. The SAX planes show all of the walls, except the apex. The best blood supply is at the base of the heart. \n\n\nHYPERDYNAMIC \ncompensatory decrease in systolic wall thickening \n\n\nHYPOKINETIC \nslow moving wall shows decrease in fractional shortening \n\n\nAKINETIC \nwall may thin in systole \n\n\nPARADOXIC \nwall motion is compensatory and moves opposite of normal \n\n\nDYSKINETIC \nwall motion compensates for abnormal adjacent walls
