There is a PVC approximately half-way across the rhythm strip with a compensatory pause which allows you to notice a P wave \u2013 and the ventricular pacer follows the atrial activity. This is a <strong>dual chamber pacer<\/strong>, which is more physiologic than a single lead ventricular pacemaker. The pacer allows the ventricle to follow the sinus rate during exercise or other situations of appropriate increased heart rate.<\/p>\n<p><a href=\"http:\/\/torreyekg.com\/wp-content\/uploads\/2015\/10\/Screen-Shot-2015-10-12-at-8.22.03-AM.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-300 size-full\" src=\"http:\/\/torreyekg.com\/wp-content\/uploads\/2015\/10\/Screen-Shot-2015-10-12-at-8.22.03-AM.png\" alt=\"Screen Shot 2015-10-12 at 8.22.03 AM\" width=\"433\" height=\"116\" srcset=\"https:\/\/torreyekg.com\/wp-content\/uploads\/2015\/10\/Screen-Shot-2015-10-12-at-8.22.03-AM.png 433w, https:\/\/torreyekg.com\/wp-content\/uploads\/2015\/10\/Screen-Shot-2015-10-12-at-8.22.03-AM-300x80.png 300w\" sizes=\"auto, (max-width: 433px) 100vw, 433px\" \/><\/a><br \/>\nRhythm strip \u2013 4<sup>th<\/sup> beat is PVC with following compensatory pause revealing P waves with following ventricular paced beats.<\/p>\n<p>This elder man is febrile and dehydrated \u2013 both good reasons for sinus tachycardia at 125\/minute.
