The baseline, seen best in the lower lead at 160%, show no organized atrial rhythm, and the rate is irregularly irregular. This second strip is probably afib.<\/p>\n<p>If the QRS complexes had been similar between the two strips, the first strip would be more consistent with junctional escape failure or sinus arrest without a ventricular escape, but here is more consistent with an idioventricular rhythm.<\/p>\n<p><strong>Final Impression?<\/strong><\/p>\n<p>1) agonal ventricular bradycardia @ ~35 bpm to asystole<br \/>\n2) atrial fibrillation with wide complexes @ ~75 bpm.<\/p>\n<p><strong>Management implications:<\/strong><\/p>\n<p>Asystole is mimicked perfectly by leads falling off or by low gain. Check leads, check other leads, and if you were never able to see any complexes- check pulse (and have someone confirm gain is not down) before you start doing compressions.<\/p>\n<p><strong>\u00a0The Take-home Point:<\/strong><\/p>\n<p>Wide bradycardic rhythms are often termed &#8216;agonal&#8217; rhythms are they are common terminal rhythms. The QRS&#8217;s visualized may or may not actually be pumping any blood, so just because you see an organized rhythm on the monitor doesn&#8217;t mean the patient has a pulse, or is perfusing her brain.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><em id=\"__mceDel\"><a href=\"http:\/\/www.electricant.net\/ekg\/wp-content\/uploads\/2013\/01\/1purple_star.jpg\"><img loading=\"lazy\" decoding=\"async\" alt=\"1purple_star\" src=\"http:\/\/www.electricant.net\/ekg\/wp-content\/uploads\/2013\/01\/1purple_star.jpg\" width=\"18\" height=\"18\" \/><\/a>One star strip.
