Key result
Restoring sinus rhythm in severe tachycardia-induced cardiomyopathy with shock is linked to major LVEF normalization.
Why the study?
Does urgent rhythm or rate control improve LVEF and functional status in patients with severe tachycardia-induced cardiomyopathy and cardiogenic shock?
Does urgent rhythm or rate control improve LVEF and functional status in patients with severe tachycardia-induced cardiomyopathy and cardiogenic shock?
Restoration of sinus rhythm via ablation or other means in severe tachycardia-induced cardiomyopathy with cardiogenic shock significantly improves LVEF and functional status.
May support urgent rhythm control in severe TIC with shock; hypothesis-generating, needs RCTs before practice change.
= 0.002). Conclusion Restoration and maintenance of sinus rhythm in severe TIC with cardiogenic shock and atrial arrhythmias lead to a major increase or normalization of LVEF, reduction of ventricular dimensions, and improvement in functional status. Ablation is efficient in long-term maintenance of sinus rhythm and may be proposed early in refractory cases.
