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

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

I've had about five ekgs in the past two years and a eco gram and they couldn't find anything wrong so my question could itbe aniexty for my chestpain?

Yes, perhaps: Chest pains in young and healthy people are common. The most common reasons include: musculoskeletal aches and pains, gastroesophageal reflux, and a condition called fibromyalgia. In each of these, the ekgs and echocardiogram would be expected to be normal. ...Read more

Anxiety or distress?: If all the medical causes are reliably eliminated, then I would consider whether anxiety or distress may be the culprit. Anxiety is often associated with an elevated heart rate; with panic attacks, heart rate can be markedly elevated. Also, people can become hyperaware, making it worse. Rarely, medical conditions may cause high stress hormone levels, unlikely but sometimes worth checking. ...Read more

Had EKG it was fine that's three this year question is what could cause my chest pain it's sharp pain stabbing could it be my acid reflux or aniexty?

?musculoskeletal: Chest pain in a 22 yo is rarely causec by heart problems ; the normal ekg's suggest your heart is fine. Reflux or anxiety can cause chest pain that is usually squeezing or a pressure/tightness. Sharp stabbing pain makes me suspect a musculoskeletal cause. Consider seeing an osteopath who does manipulation or a good chiropractor- see http://bit.Ly/1kgd0xp acupuncture or homeopathy may also help. ...Read more

Follow up question: my friend has had a clear ekg, been cleared, for asthma and still has shooting left arm pain/chest twinges. What should she do?

Follow up question: my friend has had a clear ekg, been cleared, for asthma and still has shooting left arm pain/chest twinges. What should she do?

Further test: Depends how old your friend is as well as the medical history. In a teenager, it rarely could be anything serious unless he/she has a history of congenital cardiac problems or sudden death in the family. In an older patient, it would be concerning for heart disease. If symptoms persist, see their doctor for further evaluation/treatment. ...Read more

I had asked the question about my pulse rest @ 150. I had EKG & it showed all norm but sinus tachycardia 150 at rest. Is this ok? It wasn't vt or svt

Tachycardia: If the ECG was sinus tachycardia you needn't worry about ventricular tachycardia. Svt is usually faster. A rate of 150 is often aflutter with 2:1 block. If your physician is confident it is sinus tachycardia then it shouldn't be a problem. You may want to ask his/her opinion as to what is thought to be the cause. ...Read more
