Is A Small Q Wave On An Ecg Significant
Probably not: By definition, a "significant" q wave must be > than 40 msec in duration or > than 25-33% (depends on the reference) of the r wave height. Even by that criteria, many electrocardigraphically significant q waves are seen in people with normal cardiac echo's and mri's. ...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
My dad had a MI 3mths later on ECG the report said inferolateral st sagging and 'surprisingly no q wave' what does this mean?
Cardiology.Wat relarevance dose a Q Wave have on lead 3 of an EKG.Where dose intrascapula fit is this part of another condition? and affects the heart
None.: It is not uncommon for young adults to have Q waves. These are normal and are the first activation of the bottom of the heart, between the main pumping chambers, called the interventricular septum. After that, it splits into Left and Right sides but that first Q wave is picked up as the initial beat of the ventricles before spreading out into the main heart muscles that make the main Signal. ...Read more
I have chest pain more on swallowing, 12 lead ecg. Small Q waves in inferior leads plus v5 and 6, what could be wrong?
Chest pain: It appears you are already under care of a physician having had an ekg done. If you have q waves, it may indicate old myocardial infarction. But we have to take into account your symptoms, your risk factors before deciding on further testing like a nuclear stress test, or a cardiac cath. Your primary care physician or cardiologist would be able to guide you ...Read more
What does a notched R wave in lead 3 on ECG represent? Is this significant in a 20 year old male with structurally normal heart?
Probably Normal: Without viewing your EKG and knowing more about the characteristics of the R-wave (QRS duration, etc) it is difficult to say for certain but most likely represents a nonspecific intraventricular conduction delay. In an otherwise healthy asymptomatic 20 year old without structural heart disease it is an interesting incidental finding of no clinical significance. ...Read more
