CARDIAC CODEX / GLOSSARY / RCES

Tiered therapy programming

An ICD & CRT Therapy term on the RCES exam blueprint, defined for cath lab and EP clinicians.

Detected ventricular arrhythmias are typically classified into zones (e.g., a slower VT zone and a faster VF zone) with different response algorithms: anti-tachycardia pacing (ATP) — rapid pacing pulses delivered to try to painlessly terminate a reentrant VT before resorting to a shock — is commonly programmed for the VT zone, while the VF zone proceeds directly to shock therapy given the higher risk of hemodynamic collapse and lower likelihood of ATP success at very fast rates.
