Ecg Changes For Heart Attack
Q waves: Some heart attacks do not show and even ones that do, may only be temporary. That said, q waves, if of sufficient voltage and if they follow known patterns, are the way of diagnosing heart attack by ekg. (caution: not all q waves are indicative of heart attack!). ...Read moreSee 1 more doctor answer
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
ECG: Usually always but nothing is always.Get a more detailed answer ›
My ECG was abnormal with a 'probable anterospetal infract age indeterm' - Q >30ms, Tneg, V1-V3. Does this mean I had a heart attack?
Very little : Unfortunately, the conventional ECG is older technology, invented more than 100 years ago. It is only accurate for rhythm disturbances and does not detect lack of blood supply to the heart at all! a new and much better technology based a systems engineering has emerged! it is called multifunction cardiogram! http://en.M.Wikipedia.Org/wiki/multifunction_cardiogram. ...Read moreSee 2 more doctor answers
How good is an ECG combined with a 24h Holter in detecting a previous heart attack, both overt and silent?
Probably: Ecg monitors provide information as to rate, rhythm and pattern of our heart. When a person is having an acute "heart attack" , usually the pattern of the normal heart changes. The pattern may show elevations in areas that are not there in normal or non-ischemic hearts or irregular heart beats. If you think you are having a heart attack, immediately seek out medical attention or call 911. ...Read moreSee 1 more doctor answer
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
