Recurrent LPS and arrhythmias prior to death.

<p>Telemetry tracings from a mouse that died 39 days after weekly LPS 10 mg/kg i.p. Each strip is 2.5 seconds. The mouse was in sinus rhythm 552 beats per minute (bpm) at baseline at 1:00 p.m. Two hours later, an accelerated idioventricular rhythm (AIVR) or slow ventricular tachycardia (VT) with fusion complexes with sinus beats developed (3:01 pm), with an AIVR or slow VT at 648 bpm at 3:02 pm. The mouse returned to sinus rhythm at 625 bpm at 4:00 pm. One hour later, there was sinus exit block with slow idioventricular escape rhythm (4:56 pm), and then high degree AV block (5:02 pm) shortly before death.
