Although they appear similar in morphology to supraventricular beats, both are PVCs by criteria that define the difference between PVC and PAC.\n<p>Both beats are followed by a pause \u2013 in these beats, a compensatory pause, which implies that the next P wave was undisturbed by the premature beat.  Another way of saying the same thing is that the sinus P waves \u201cmarch through\u201d the premature beat, or that the sinus metronome marked by regular P and QRS complexes is undisturbed.  Each of these descriptions say the same thing \u2013 these premature beats are both PVCs!<br \/>\n<\/p><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>What is the etiology of the early beats seen here?
