Therapeutic hypothermia is beneficial and increases the probability of brain recovery in patients with coma due to cardiac arrest with a nonshockable heart rhythm.

Medications are frequently used in the emergency department to help restore conduction of normal cardiac electrophysiology. This article will briefly review arrhythmias and discuss commonly used and new medications with their indications, side effect profile, and contraindications to use.

This two-part series presents a review of the current evidence on atrial fibrillation. The first part includes its definition, classification, risk factors, comorbidities, evaluation, and acute management of newly diagnosed patients. The second part will focus on long-term management, including risk factor modification, rate and rhythm control measures, stroke risk stratification, and anticoagulation management.

The workup of suspected acute coronary syndrome in the emergency department is an ever-evolving process, and staying up-to-date can be difficult. This review aims to empower providers to maximize diagnostic precision in a patient-centered and resource-conscious way.

This article addresses specifics of the cardiac testing options, considering their appropriate indications, choices of approach, risks, and costs.

This two-part series will look at the rationale and causes of inappropriate testing and how to select the best, most appropriate cardiac test for each patient. The first part will focus on the theory of ordering tests and strategies to minimize unnecessary testing while the second part will focus on when and how to select each individual test given the patient's clinical scenario.

Lau and colleagues describe a novel infectious problem — diffuse granulomatous encephalitis due to Mycobacterium chimaera infection occurring after cardiac surgery.

This prospective, multicenter cohort study aimed to determine the utility of electroencephalographic reactivity (EEG-R) testing in neurological prognostication of comatose patients after cardiac arrest. The authors found that EEG-R testing, by itself, is not sufficiently reliable to predict neurological outcomes after cardiac arrest.
