Septal infarct?

[Sissy162]

69 yr old male had CABG 7/07 (RCA).  EKG's post op reveal NSR.  
Recent pre-op routine EKG states:  "NSR. Now present is Right Non-specific intra ventricular conduction delay, nonspecific ST and T wave abnormality."  Please explain.   MarE

NSR is normal sinus rhythm. The right-upper chamber node produces electrical impulses that are transmitted to polarize and depolarize specific heart cells.  This action contracts and then relaxes heart tissue for heart pumping contractions and relaxation for filling heart chamber.

Nonspecific ST-T wave abnormalities, is frequently used when the clinical data are not available to correlate with the ECG findings. This does not mean that the ECG changes are unimportant! It is the responsibility of the clinician providing care for the patient to ascertain the importance of the ECG findings.  It is not an uncommon EKG tracing, often meaningless and requires supporting evidence for any dx.   There are heart drugs e.g., digoxin, quinidine, tricyclics, and many others and there can electrolyte abnormalities of potassium, magnesium, calcium that will cause an non-specific ST-

The electrical impulses follow a conductive pathway and non-specific intra ventricular indicates there may be a right side interruption (in matter discussed, can be left side) to an impulse causing dyssynchrony.

Evidence of ventricular dyssynchrony is noted on the electrocardiogram as a bundle branch block, or nonspecific intraventricular conduction delay (QRS > 120 ms... tracing on graph) and delayed atrioventricular (AV) conduction (PR interval on an EKG graph).  Common skipped heartbeats are a result.
