What does a normal EKG look like versus an abnormal one from an undetected heart attack ?

What does a normal EKG look like versus an abnormal one from an undetected heart attack ?

A normal EKG: Because some areas of the heart are electrically silent, one can have a full blown heart attack with an entirely normal ekg. When the ekg is destined to become abnormal, it often lags, not showing changes early on: hence the need for "serial ekgs" (done daily). The adage "treat the patient, not the ekg" hasn't changed over the years. ...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

EKG Question - What would cause a small dip after the T wave? It's like a scoop about 1mm deep. Is this normal or should it be isoelectric after T?

EKG Question - What would cause a small dip after the T wave? It's like a scoop about 1mm deep. Is this normal or should it be isoelectric after T?

Yes, isoelectric if: after the T-wave. The most likely explanation is that the dip is the terminal portion of the T-wave, terminal inversion due to muscle still in recovery (to be finished late, have to leave for other obligations) ...Read more

What should p waves look like in lead v1? What does it mean if different on some EKG?one will show completely positive,one fully negative,another biph

There can be a lot: of normal variability to the p-wave morphology in V1. More so in women. In general a biphasic or mostly upright p wave is usual. Certainly you could have an ectopic atrial activation in which case the morphology would be altered. Physical positioning (sitting, lying or at 30 degrees) for the EKG will also make a difference. Lead position too. Regardless it is usually of no clinical significance. ...Read more

"i had an EKG done today and i observed the results stated probably normal for age what does this mean?"

ECG: 'probably normal for age' basically means normal. There are some subtleties related to age but few make significant difference except when there is a wide difference between age and interpretation. ...Read more

No: I suspect you have been getting chest pain during your panic attacks. A normal EKG at the time of the chest pain rules out an acute coronary syndrome in most people. You should talk to your doctor about getting a stress test just to be sure. ...Read more

Chest pains but a normal EKG should I not be worried?

Chest pains but a normal EKG should I not be worried?

Anxiety and Panic: Hundreds of young people spend thousands of dollars every day seeking emergent or expensive medical care for 'chest pains' only to be told that they are normal and may have anxiety. Many humans hold their tension in their chest. There are lots of muscles in the chest that can spasm. I would get a good family physician to guide you through this; to reassure you and to help you deal better. ...Read more
