What does pr interval .12, qrs .09 and qt interval .34 mean on an ecg?

Intervals: It means those intervals are normal, it doesn't say anything about the rest of the ecg. ...Read more

What are prolonged qt intervals?

What are prolonged qt intervals?

ECG measurement: Qt intervals are measured on a heart electrocardiogram (ecg). They measure "repolarization". Longer qt intervals may be associated with arrhythmias (irregular heart beats) such as torsades de pointes or ventricular tachycardia (vt). There are also inherited disorders that are associated with prolong qt intervals. ...Read more

What does left axis deviation, ST depression, and abnormal Twave, Heart rate 134 mean?  PR interval 145, P Duration107, T Duration 230, QRS duratio...

Electrocardiogram: The electrocardiogram (ECG, or EKG in German) is a recording of the electrical activity of the heart. Sometimes a computer gives a prelim interpretation, then a doctor gives a final reading. The findings you listed are details but not interpretation. Depending on clinical context (age, symptoms, history) and comparison with prior ECGs, ST depression might mean ischemia and need further testing. ...Read more

Many possibilities : Phillip,
Many of the findings you mention can be normal variants but may also represent more concerning issues such as blocked arteries. I would note that you don't want to rely on a computer interpretation of the ECG and should make sure a cardiologist has reviewed it.
Other things to remember is that you want to review the ECG in the context of symptoms, risk factors etc. ...Read more

Ecg results- pr interval (110ms), qrs duration (90ms), qt, qtc- (352, 425), p-t-r axes- (8, 35, 110). Is this normal?

Ecg results- pr interval (110ms), qrs duration (90ms), qt, qtc- (352, 425), p-t-r axes- (8, 35, 110). Is this normal?

Usually benign: Pr interval depends on many factors. Pr shortens at faster hrs. Some people have short pr intervals even at slower rates, so-called "lgl syndrome", completely benign. Rarely, a short pr can be due to an accessory pathway, also called wpw, but any physician should be able to take one look at the ECG and determine if that's the case or not. Even if it is, there's nothing to do if you're asymptomatic. ...Read more

Ekg results; vent 81bpm, p duration 122, qrs duration 138, pr interval 178, qt/qtc 392/428? How abnormal is this? Only diagnosis I have is lbbb.

Depends: Lbbb is abnormal. It may be associated with coronary heart disease, high blood pressure, an enlarged heart, or cardiomyopathy (heart muscle disease). Rarely, it can be congenital (present at birth). The significance of lbbb depends on the presence or absence of associated heart disease and whether it is a new finding or has been present for several years. May need echocardiogram and/or heart cath. ...Read more

Is this normal qt interval 335 and qtc 435 and heart rate 104? Ecg showed sinus tachycardia,

Is this normal qt interval 335 and qtc 435 and heart rate 104? Ecg showed sinus tachycardia,

HR slightly fast : A hr of 104 at rest (sinus tach) is slightly higher than the normal range of hr's between 60-100 at rest. That said, there could be plenty of reasons that this coud happen (like anxiety, dehydration, caffeine, pain, etc). Also anemia, hyperthyroidism , breathing or pulmonary problems could result in physiologically appropriate faster hr's. Inappropriate sinus tach considered if no cause seen. ...Read more

See below: Your atrial septal defect and atrial septal aneurysm are sufficient to account for a RAD. You need to ask the echo reader to quantitate the amount of left to right shunting that is present. If significant. the ASD should be closed. The other parameters of your EKG are normal. ...Read more

Vent rat 66bpm, pr int 141 ms, qrs dur 89ms, qt/qtc 415/429 ms, p-r-t axes 65 29 37, qtcb 437 ms, atypical ECG low qrs voltage. What does the ECG mea?

Abnormal ECG: The major finding is low voltage. Causes of low voltage include: pericardial effusion, pleural effusion, overweight, emphysema, pneumothorax, contrictive pericarditidis, previous massive mi, end-stage dilated cardiomyopathy, infiltrative myocardial diseases — i.e. Restrictive cardiomyopathy due to amyloidosis, sarcoidosis, haemochromatosis; scleroderma, myxoedema (severe low thyroid hormone). ...Read more

QTc interval 483. Is this serious?

QTc interval 483. Is this serious?

Normal: Your QTc is on the upper end of normal range, < 500 ms. The QT or QTc changes based on your heart rate and other factors. Some medications can make the QT longer (some antibiotics, some psychiatric medications, some heart medications, as well as others) so it is important that you talk to your doctor about it to make sure you don't take any of these. Also discuss family history of heart attacks. ...Read more
