2. Indications

The Evia HF and Evia HF-T Cardiac Resynchronization Therapy Pacemakers (CRT-Ps) are indicated

for patients who have moderate to severe heart failure (NYHA Class III/IV), including left ventricular

dysfunction (EF ≤ 35%) and QRS ≥ 120 ms and remain symptomatic despite stable, optimal heart

failure drug therapy.
