The Case:
A 72-year-old woman presents with chest pain. Her ECG is abnormal in a few ST segements, but not because of your typical ST segment elevation. Here we relay a discussion of a particular channelopathy important to consider for the emergency physician.

The Case:
A 40-year-old female presents to the emergency department for palpitations and lightheadedness. She has a history of depression on citalopram, migraines on amitriptyline, and was recently prescribed tramadol after she broke her wrist. She is well-appearing, and while being placed on the monitor, she becomes anxious, stating the symptoms are recurring. An ECG is performed, with Figure 1 serving as a representative EKG. The patient is awake and talking. Defibrillator pads are placed and 2 g IV magnesium is administered twice each over ten minutes resulting in the termination of the prior rhythm. A repeat EKG is obtained and is similar to that in Figure 2. The patient remains stable, but then degenerates again into an aberrant rhythm. What do you do next?
