Her vital signs were within normal limits except for bradycardia at 55 bpm. It is probably sinus bradycardia with very small/depressed P-waves and prolonged PR interval. See these other related cases: A patient with cardiac arrest, ROSC, and right bundle branch block (RBBB). Is this just right bundle branch block?

There is also bradycardia. Bradycardia puts patients at risk for "pause-dependent" Torsades de Pointes. Torsades in acquired long QT is much more likely in bradycardia because the QT interval following a long pause is longer still. If cardiac arrest from hypokalemia is imminent (i.e., mEq/L, from 1.9

Arrhythmia In simple words, arrhythmia refers to an irregular heartbeat. A fast heartbeat is called tachycardia, while a slow heartbeat is called bradycardia in medical terms. Cardiac arrest Cardiac arrest is a medical emergency in which the heart stops pumping blood to the body.

That said — obvious findings include: i ) Marked bradycardia! — L addergram I llustration : At this point — I needed to work out, and then draw a laddergram that I could then verify to ensure a plausible mechanism for today's arrhythmia. Unfortunately, before this could be accomplished — the patient went into cardiac arrest.

I focus my comments purely on a few sophisticated concepts in arrhythmia recognition — fully aware that specific rhythm disorders with calcium channel toxicity need not be treated per se, beyond providing cardiovascular support. It's always rewarding and mutually educational to discuss interesting aspects of arrhythmia interpretation.

Prior to Mizusawa's study, it was thought that the incidence of syncope, arrhythmia, or SCD in this cohort was low [7]. In light of the risk of arrhythmia events observed in the Mizusawa trial, a formal EP study might be reasonable to obtain in those with fever induced asymptomatic Brugada ECG changes to help risk stratify these patients.

This ECG shows a sinus bradycardia with a normal conduction pattern (normal PR, normal QRS, and normal QTc), normal axis, normal R-wave progression, normal voltages. Hypothermia can also produce bradycardia and J waves, with a pseudo-STEMI pattern. ECG met STEMI criteria and was labeled STEMI by computer interpretation.
