ECG results

First time I have gone through ECG with the fallowing results. 45 years male never smoked before, highc holesterol 309. I woluld appreciate some comments on these results.
Thanks in advance.

Rate 70
PR 148 Normal sinus rhythm rate 70
QRSD 101 Borderline left atrial abnormality
QT 368 Incomplete right bundle branch block
QTc 397

Axis

P 68
QRS 62
T 67

You should post that on the expert forum, there are doctors to answer. Used to be some nurses on that board those were also patients, they were explaining sometimes result reports but I don’t see them around now. Good luck.

The high cholesterol aside and in regard to the EKG tracings.  An EKG requires further clinical evidence before any diagnosis and that includes your symptoms.  

For some insight:  An EKG monitors the electrical conduction system of the heart, which produces the electrical activity measured by the electrocardiogram, is composed of the sinoatrial (SA) node (right atrium and beginning of electrical impulses), the following are the pathways for the electrical impulse: internodal and interatrial conduction tracts, the atrioventricular (AV) junction (consisting of the atrioventricular node and the bundle of His), the right and left bundle branches, and the Purkinje fibers.

PR interval represents impulse the atria (upper chamber) to ventricular (lower chamber) conduction time through His bundle (impulse pathways)  It includes P wave and PR segment. The horizontal axis of the EKG output is a measurement in msecs.  The verticle axis is measured in mvolts (amplitude).

If the PR interval is greater than 0.2 sec, then an AV block is present (could be). There are several types of AV blocks: Your EKG tracing indicates a time interval of 148.  The prolonged time indicates a delay of signal (impulse) from the atria to the ventricles.  The delay can be attributed right bundle branch block, can also be caused by electrolyte imbalance, medication, diet, etc.  

Borderline left atrial abnormality indicates the LA may be slightly enlarged (need more information).  Rhythm 70 indicates your heart rate is normal.
