Arrhythmias During Pregnancy: Ventricular Tachycardia in the Setting of Maternal Beta Thalassemia Minor.

Non-sustained ventricular tachycardia (NSVT) poses significant risks during pregnancy, particularly in patients with underlying conditions such as β-thalassemia. We present a case of a 29-year-old pregnant woman with a history of β-thalassemia minor who experienced NSVT at 27 weeks gestation. Despite initial concerns for structural heart disease, the workup was unrevealing.

Adverse events of undiluted intravenous push levetiracetam.

Background: In patients who experience a seizure, the seizure duration is a strong indicator of prognosis. Thus, reducing time to antiepileptic medications in patients who are actively seizing is critical. While findings from retrospective studies suggest that the rapid administration of undiluted intravenous (IV) levetiracetam may be safe, some gaps in the literature remain.

Resolution of Left Bundle Branch Block After Calcium Administration in the Prehospital Setting.

Hyperkalemia is a medical emergency with potentially severe consequences that can be avoided by early recognition and effective treatment. Electrocardiogram (ECG) changes can help elucidate hyperkalemia prior to obtaining lab results and assist in early decisions on treatment, especially in the prehospital setting. ECG changes commonly associated with hyperkalemia are peaked T-waves, PR prolongation, P-wave flattening, QRS widening, or a sine-wave pattern at severely elevated potassium levels.
