A member asked:
On ecg readings what does occasional premature ectopic complexes mean, a rightward axis, a short pr, and low voltage qrs?
A doctor has provided 1 answer
Pre-excitation?: There is a short delay between the times the upper chambers (atria) contract and the lower chambers (ventricles). The two events are seen on the ekg as the p and r waves. If that is shorter than 120 msec, that can mean an accessory pathway that is bypassing the normal conduction system and cause "pre-excitation". Look up WPW or lgl syndrome. See an electrophysiologist about possible ablation.
