An extremely wide QRS complex tachycardia induced by anamorelin

Abstract

Anamorelin, a ghrelin receptor agonist, is used for cancer-related cachexia but can induce life-threatening arrhythmias. A case study illustrates an extremely wide QRS tachycardia, posing diagnostic challenges. Anamorelin cessation led to normalization, highlighting the importance of ECG monitoring, particularly in liver-compromised patients, and hemodynamic support are crucial during suspected toxicity.
