This is a research study that aims to understand if giving a lower dose of treatment all at once is as effective and safe as dividing it into three smaller doses for patients with a heart condition called refractory ventricular tachycardia (VT). These patients have not exhibited positive responses to conventional medications or procedures. This study aims to explore whether an alternative approach could yield more beneficial outcomes.
