I don't know anything about medicine, I just want to know if a inverted P wave on ECG can be nothing bad.?

Could be fine: It's usually fine. The exact location the P wave comes from in the heart moves up and down in the right atrium along something called the crista terminalis. As it does so, the P wave morphology can change. Your specific situation may vary, of course. ...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 have EDS & being tested for vascular EDS. I had a recent ECG showing inverted t-wave in v2&v3. I'm 30y/old. I have frequent chest stabbing pain & palpitations & fainting for 8 years+. Does my ECG point towards V-EDS? Should I be concerned?

Ehlers Danlos: The answer to your question requires an evaluation, physical exam, and testing. A chest xray can be helpful, but a CT-scan of the chest is more sensitive. The ECG is helpful but not diagnostic. If you have an Aortic aneurysm, that is serious and mandates treatment. Please do complete the testing recommended by your doctors. Good luck. ...Read more

ECG comparison changes inverted T-wave. I had spinal injury before the 1st ECG cervical thoracic Lumbosacral neuritis. Is it Related to spine or CNS?

ECG comparison changes inverted T-wave. I had spinal injury before the 1st ECG cervical thoracic Lumbosacral neuritis. Is it Related to spine or CNS?

Yes possibly: It is well documented that there is a whole gamut of ST/T changes that can occur in the setting of CNS injury, ranging from subtle ST Changes, sinus arrhythmia/sinus tachycardia, etc. IF you have risk factors for CAD, and are having chest pain/pressure, then see a cradiologist sooner than later. ...Read more

Recently my ECG was done and doc wrote t inverted on the report. What does t inversion mean?

Recently my ECG was done and doc wrote t inverted on the report. What does t inversion mean?

Depends...: The significance of t wave inversions is almost impossible to assess without taking into account the history and examination findings in a given patient; i.e., ECG findings can be difficult to interpret when viewed in isolation.

T wave inversions can be due to a long list of possible diagnoses, some benign/non-specific, others concerning, and usually require further assessment. ...Read more

Always had abnormal ECG due to inverted Twaves last ECG said ST & Twave abnormality, consider Anterior ischemia cant rule out inferior infarct. Worry?

Always had abnormal ECG due to inverted Twaves last ECG said ST & Twave abnormality, consider Anterior ischemia cant rule out inferior infarct. Worry?

Depends: You list "stress echocardiography" - was this normal? It's a much more accurate test than just an ordinary, resting EKG. If your stress echo was normal, forget the EKG but remember to always warn future doctors that you have a "normal funky-looking EKG" so they don't worry. ...Read more

Can incorrect lead placement lead to an inverted t-wave on ekg?

Can incorrect lead placement lead to an inverted t-wave on ekg?

Yes: Yes, absolutely. Avr usually has inverted t-waves normally. If you invert left and right arm electrodes, avr becomes avl so now avl has inverted t waves (where as typically it does not). ...Read more

Is an upright P wave V1 and inverted P wave aVL with tachycardia indicative of ectopic rhythm? Other ekg shows biphasic P wave V1, upright P wave aVL

Is an upright P wave V1 and inverted P wave aVL with tachycardia indicative of ectopic rhythm? Other ekg shows biphasic P wave V1, upright P wave aVL

If the tachycardia: Is occurring at rest with changes in the P wave morphology then it might be an ectopic atrial tachycardia. If it is occurring during exercise it is not diagnostic and may still be a normal sinus mechanism. ...Read more

A doctor said my inverted t-waves on EKG looked deeper when compared 2 a different ekg, I asked him 2 explain but I didn't understand the medical term?

T Waves: Inverted T waves can be (key words) sign of lack of blood flow to the heart muscle. However, some people have abnormal ECG's without any blockages. As long as you are without chest pain your ECG should not worry you. Your age and the fact that you are female it is highly unlikely that you have obstructive coronary disease. Hope this helps. ...Read more

Ekg shows inverted t waves. Normal sinus rythmn. Palpitations feel like skipped beat followed by two hard slow thumps then back to normal. What is it?

PVC.: Sounds like you have a premature ventricular contractions or premature atrial contractions although I think these less likely. I would not be worried about inverted t waves in the absence of any other cardiac symptoms. To be absolutely sure these are what I think they are it would be reasonable to obtain a holter or event monitor and capture a few of these. ...Read more

A couple days ago my EKG was normal. Now I have inverted t waves. My blood work is normal. If my blood work shows no heart concern should I worry?

Depends: Why did you have a repeat EKG within 2 days in the first place? T wave inversion can be seen normally in certain leads depending on position or breathing specially in young individuals. A more thorough history and exam by your physician is more likely to yield a diagnosis than a blood test. Know that EKG changes can be seen in other conditions such as blood clot in the lungs, electrolyte changes, ...Read more

A couple days ago I went to the ER (chest tightness) and everything came back normal, EKG etc. Today I went back and I have inverted t waves. Blood ok?

A couple days ago I went to the ER (chest tightness) and everything came back normal, EKG etc. Today I went back and I have inverted t waves. Blood ok?

EKG changes: Hmm. If your 2 EKGs are different there could be multiple explanations. A different physical position Sitting/reclining/laying flat will all change an EKG. Lead position is also important. On the other hand, an EKG is often insensitive to cardiac damage (misses maybe 15-20% of small MIs). I think you should see a cardiologist to be sure. If you get any more chest symptoms go to ER now. ...Read more

Can azithromycin cause inverted t waves? EKG was norm until I started taking this. Now I have inverted t waves but normal blood work as far as heart.

Can azithromycin cause inverted t waves? EKG was norm until I started taking this. Now I have inverted t waves but normal blood work as far as heart.

No: Ordinarily, no. But azithromycin can prolong an interval in the EKG called QT. The changes in your EKG are non specific and may or may not be significant. You need to to talk this out with your doctor or see a cardiologist if your primary MD or you remain concerned ...Read more

Chest tightness for week. Normal EKG other than my regular inverted twaves. Seems like may be worse on empty stomach and sometimes pain under right rib?

Chest tightness for week. Normal EKG other than my regular inverted twaves. Seems like may be worse on empty stomach and sometimes pain under right rib?

Other symptoms?: If you are having only intermittent chest discomfort, not related to exertion, it may be musculoskeletal. Changes with your meal pattern may point to a gastrointestinal cause. If you have risk factors like diabetes, smoking, high cholesterol or hypertension, your overall risk is increased, however it is best to have your doctor examine you to determine if your need any further testing. ...Read more

What are all the possible causes for a pointed P wave on an ECG?

What are all the possible causes for a pointed P wave on an ECG?

Depends: But if truly a P wave, it depends on how pointy, as in height. P waves with an amplitude greater than 2.5 small boxes in lead 2 or 1.5 boxes in lead V1 suggest right atrial enlargement. If you've had an echocardiogram (sound study of the heart) like is mentioned in your "Procedures" then this would be more visible on this study. It may not mean anything. ...Read more

Normal ECG with abnormal P waves doctors not worried don't understand it all?

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

Male 22. Got a portable 3 lead ECG at home. My P wave can't really be seen but my mums can? How come?

Ectopic atrial rhyth: You might have a ectopic atrial rhythm - which means your arial beats instead of originating in the sa node - originates else where. It is benign and nothing to worry about. Get a standard 12 lead ekg to check. ...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

My ECG today showed pointed and long P waves and paramedics told me it was abnormal what would cause the P waves to be like this : (?

"p". ..?: Did the paramedics say "p" as in "papa" or "t" as in "tango"? Abnormal P waves can indicate an atrial abnormality, but the echo you list is far more accurate. Tall or "tented" T waves can be normal but can indicate elevated potassium. "Long" T waves (I suspect we'd call them "flat") are a non-specific change; abnormal but not diagnostic of anything. Hyperventilation (anxiety) can do it. ...Read more
