PREMATURE JUNCTIONAL CONTRACTIONS

ËÅѡࡳ±ì¡ÒÃÇÔ¹Ô¨©Ñ Basic R-R interval is regular, but interrupted intermittently Irregular R-R interval is short (premature QRS) QRS duration of early complex is normal QRS morphology of early complex is similar to regular QRS Early QRS is not preceded by a P wave If QRS morphology of the early complex is not similar to the regular QRS and there is no preceding P wave, the diagnosis is premature ventricular contraction ¡ÒÃÇÔ¹Ô¨©ÑÂá¡âä Premature atrial contraction Prematuure ventricular contraction Wandering atrial pacemaker
