Heart rate is well established in the diagnosis of shock; however, the mechanisms regulating heart rate, systemic resistance and blood pressure remain unclear. The concept of heart rate control in shock-related tachycardia has been known for about 50 years. Elevated heart rates in septic shock have been identified as an indicator of increasingly inefficient hemodynamics, worsening perfusion and organ function as well as of an unfavourable prognosis. Many drugs used for heart rate control also lower blood pressure. The challenge of this therapeutic concept is achieving optimal heart rate control without provoking critical hypotension. Only in recent years has the development of highly cardioselective, short- and ultrashort-acting β‑blockers such as esmolol and landiolol made it possible to prove the feasibility and usefulness of heart rate control in certain types of shock. © 2022.
