I would recommend cardiology only if you were having symptoms of chest pain, shortness or breath, other things such as lack of stamina, etc. Otherwise, a good internist can deal with this EKG. The elevated heart rate (tachycardia) will automatically CAUSE a short PR interval...so that goes together. However, if you are consistently running a high rate you may need additional workup.

Brief Answer:
Tachycardia is a risk factor for pulmonary emboli

Detailed Answer:
Tachycardia (Heartrate >100 BPM) is a well known risk factor for pulmonary emboli. Is that what you mean when you say "abnormal ECG be a pre cursor to Pulmonary Embolism?" because it's a bit of an odd way to say it but I think I know what you mean.

Tachycardia really should not confer any worries upon you with regard to your heart (in general) or the major blood vessels. There is no direct relationship between one entity and the other. Furthermore, I'm not sure I understand which types of pathologies you're concerned with in the face of a tachycardia. I don't see where an ultrasound should be ordered for any of the organs you mention based upon the presence of tachycardia.

Depending upon the actual rate of your heart and whether or not you can control that rate by straining or bearing down I might be able to envision ELECTROPHYSIOLOGICAL STUDIES of the heart. But I see no need for ultrasound of any of the organs you've mentioned. I may even see the placement of either a Holter monitor or EVENT MONITOR for 30 days based upon the tachycardia but nothing else.

I'd appreciate the favor of your providing a STAR RATING and some brief written feedback if your question has been satisfactorily answered. In addition, CLOSING THE QUERY on your end will also be most helpful.

Don't forget that my webpage to keep me abreast as to how you're doing is:
