Pharmacological Approach for Symptomatic Nonsustained Ventricular Tachycardia.

Nonsustained ventricular tachycardia (NSVT) is a common arrhythmia associated with heart failure, cardiomyopathy, coronary artery disease, electrolyte imbalances, and congenital heart disorders (Foth et al., 2023). NSVT is often asymptomatic depending on its burden percentage. However, typical NSVT presentation in the emergency department (ED) includes palpitations, near-syncope, dizziness, skipped beats, chest pain, and/or dyspnea (Katritsis et al., 2012). In some instances, NSVT can present with elevated or slightly elevated troponin from demand ischemia. A definite diagnosis of NSVT is not of high complexity; nevertheless, it is not always identified on electrocardiogram (ECG) by the time the patient arrives to the ED. Identification of NSVT usually requires prolonged cardiac monitoring, mobile cardiac telemetry (MCT), and in some instances internal loop recorder placement. The purpose of this case is to discuss the typical presentation and pharmacological approach of patients with stable NSVT.

Low-Dose Electrocution and Atrial Fibrillation.

Emergency electrocution incidents present with various injuries, which can range from minor to severe injuries including death. Cardiac-related complications have a higher mortality incidence among patients with low-voltage injuries (M. R. Zemaitis et al., 2023). When managing electrical injury patients, the literature recommends managing them as both trauma and cardiac cases. However, the diagnostic approach is based on each individual case and patient presentation. Electrical injury complications include arrhythmias, myocardial tissue damage, and conduction disturbances (Pilecky et al., 2019). The purpose of this case study is to discuss a postelectrocution atrial fibrillation case and common related arrhythmias associated with electrical injuries.
