Learning Objectives
A patient who presented with refractory supraventricular tachycardia and tachycardia-induced acute heart failure:
  1. To acknowledge that tachycardia-induced acute heart failure could progress fast, an emergency electrophysiology study with ablation prevailed as the treatment method for refractory tachycardia.
  2. To recognize coronary spasm during ablation as a rare but catastrophic complication.
  3. To understand that step-up treatment, including PCPS and catheter ablation, could increase the success rate of managing acute heart failure with tachycardia arrhythmias as a cause .
