Question (10/08/2013):

Title: Help me to understand the meaning of ECG results.

Please help me to understand the meaning of ECG results. Rate 86 PR 164 QRSD 85 QT 384 QT 459 Axis P 37 QRS -30 T 26: leftward axis QRS axis -15 to -30 Late transition QRS negative in V5 or V6 Consider left atrial enlargement P V1 -.10 mV or more negative Diffuse nonspecific T abnormalities T neg T/QRS ratios < .05 ANT/LAT/INF.

What do these readings suggest as possible condition?

Answer:

Thank you very much for your question.

Heart rate Normal Results: 60 to 100 beats per minute.

The PR interval measures from the beginning of the p wave to the beginning of the QRS. A normal range is between 120ms (3 small boxes) and 200 ms

The QRS complex is a name for the combination of three of the graphical deflections seen on a typical electrocardiogram (ECG)

The parameters for normal QRS duration have been defined as between 60ms (milliseconds) and 100ms.

In cardiology, the QT interval is a measure of the time between the start of the Q wave and the end of the T wave in the heart's electrical cycle

The literature cites the QT "normal range" as being 350-440 ms.

A P-R-T axis helps to analyze that your QRS interval is in the proper axis (no deviation into an improper axis). You have 3 axis measurenents, although you have only provided the "P" portion of those measurements. The axis is determined by which direction the electrical signals generated by your heart are traveling toward the leads of the EKG. Normal range for each of these values should be between -30 to +90. So, a "-30" is not terribly worrisome.

V4, V5, and V6 are referred to as the left precordial leads. The precordial leads view the heart's electrical activity in the so-called horizontal plane. The QRS complex should be negative in lead V1 and positive in lead V6.

Left atrial enlargement (LAE) or left atrial dilation refers to enlargement of the left atrium (LA) of the heart, and is a form of cardiomegaly.

Cardiomegaly is a medical condition wherein the heart is enlarged.

The T wave is part of the complex that doctors look at on an EKG. The T wave occurs when the heart relaxes. There are many reasons that a T wave could be abnormal. Sometimes it is just how the heart looks on EKG and it is not anything to worry about. Sometimes when the heart does not get the blood it needs (ischemia) there can be t wave changes and this requires an urgent work up. Also some of the electrolytes in blood (eg. Potassium) can cause changes in the T wave if the levels are abnormal. There are many other causes, but they are rarer.
