Normal Ecg Waves
P waves: The p wave reflects the area of your heart in which your heart beat arises - usually high in the right atrium. Abnormal p waves can indicate that your heart beat is arising in a different location, but as long as your heart rate is normal and the rest of the EKG is normal, this is not serious and often just a normal variation. ...Read more
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 had an ecg done and the t waves where flat in V5 and V6 in an older one 6 months ago the t waves where completely normal is this normal?
No but it does not: Denote any sp dz if u have no symptoms u may ignore it ...Read more
One unusual beat OK: If the rest of your EKG is truly normal, then one unusual beat is unlikely to be due to a significant heart problem. Unless there are other reasons for your potassium to be low such as vomiting, diarrhea, diuretic medicines, an otherwise healthy 23 year old will probably have a normal potassium. Of course if you are have other heart related symptoms be sure to follow up with your doctor. ...Read more
What are the possible causes for having a pointed P wave on an ecg? My ECG 5 mths ago had a normal p wave.
Right atrial large: A tall P wave (or peaked or 2.5 mm in height) in lead II is consistent with possible RAE. Right atrial enlargement. The gold standard diagnosis of RAE however would be echocardiogram or some other diagnostic test that visualises the heart, such as CT scan, MRI of heart, etc. ...Read more
I have ECG conclusion all normal except for III avf abnormal t wave. What is this? Should i take cautions? Tks
Abnormal T waves : Are not a sign of cad. During an acute coronary syndrome, an ECG may show peak t waves follow by st changes. I do not have your ECG to evaluate but i suspect are normal changes for you. If you are having symptoms like CP with activities a stress test will offer more definite diagnosis. ...Read moreSee 2 more doctor answers
Had six ecgs in a month four normal two were incornfirmed abnornality t wave and I think s wave went away when breathed in?
Abnormal ECG yesterday mon specific t wave repeat today rsr probable normal variant anterior t wave abnormality non specific please help I'm scared ?
Nothing serious: The findings you describe in your ECG are both nonspecific. Such findings do not mean that there is anything wrong with your heart. "Nonspecific T wave changes" are frequently seen in normal people, and often disappear. They are sometimes due to electrolyte changes or other transient causes which do not amount to heart disease. Please do not worry. ...Read moreSee 1 more doctor answer
Sorry 4 so many questions I'm scared to sleep due to sudden change in ECG from normal to non specific t wave abnormality in a few hours exstreme aniexty Google says sign of serious problem?
Not a problem: The T wave is the most labile wave in the ECG. T wave changes including low-amplitude T waves and abnormally inverted T waves may be the result of many cardiac and non-cardiac conditions. The normal T wave is usually in the same direction as the QRS except in the right precordial leads (see V2 below). See link for details but try not to get confused with medical jargon. Consult your MD for sp qs. ...Read moreSee 1 more doctor answer
How can a ECG go from normal ECG sinus rhythm to unspecified t wave abnormalities within a few hours?
T waves: Non specific T waves often occur on movement of the leads and are of no significance. It is also possible that they were so minimal that they were not reported in the reading of the first E.K.G. ...Read more
8 mths ago ECG was normal. 3 mths ago ECG had pointed P wave 2.5 mm. 2 days ago P wave was 3. 5mm on all leads Is the increase in amplitude and pointedness something that needs investigating & causes?
Resting ECG shows narrow and fairly deep inferior Q waves but stress test is normal. What does this mean?
Help me doc, i am really terrified. i went to do an ECG test and my result is as follows P WAVE ENLARGEMENT OTHERWISE NORMAL ECG.. please help me?
Be calm!: This probably means absolutely nothing, but is rather a normal variant. There is nothing in our literature that says anything at all about this condition. So relax, take deep breaths, get some exercise, and ask the physician who ordered the EKG if s/he has any other ideas. Don't worry, be happy! Oh, and don't smoke if you value your heart and your circulation...to other important areas. ...Read more
Hr 55 ECG showed a quick beat after the previous beat and felt a flutter then back to 55. Not PVC was normal wave formation?
Hard to say: Could be a premature atrial contraction (a PAC), or possibly a normal sinus beat in a sinus arrhythmia (a somewhat variable heart beat in an otherwise normal rhythm). Neither of those is generally a concern, but neither is typically symptomatic either. I would check in with your MD, or whoever did the ECG. ...Read more
I felt mild chest pain(left side)3-4 times in last 3 days..I carried out ECG and the report looks normal except abnormal T Wave..what it indicates?
T wave: Can be normal. Discuss with your Dr. ...Read more
Was very emotionally stressed earlier having PVCS, Ecg showed normal sinus rhythem but ONE beat had a prominent U wave? I felt like a quickish beat?
Flipped T wave in lead 3, no other abnormalities. ECG was done due to palpitations, increased HR, and lightheadedness. Normal echo. Is this okay?
Flipped T in III: Normal variant. Would check tilt test to see if heart rate increases when tilted , as you may have POTS postural orthostatic tachycardia syndrome Also check TSH/T4 , check for H pylori if any abdominal discomfort, and less commonly consider ANA, sed rate, DS DNA and ACE metanephrines and 5HIAA., if all else negative ...Read more
Are there any cardiologists that can tell me why the P wave on an ECG is pointed amplitude 2.5 mm and the U wave is tall? What are the possible causes of this if previous ECGS were normal
Standardization: a sudden increase in P amplitude and U amplitude when previous EKG was normal likely is due to change in the settings of the EKG machine with increased gain voltage amplitude which is indicated on the bottom left of the page should state 10 mm per millivolt. If this is not the case..... increased P amplitude indicates large atrium and increased U wave may indicate low potassium, or high Calcium ...Read moreSee 1 more doctor answer
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
