Atrioventricular Delay in Heart Failure Patients: How to Manage It
Since artificial heart stimulation started in the 1960s, with atrium and ventricle of the human heart being electrically connected in such a way as to give a haemodynamically optimal function, diastolic filling time has remained a challenge. In the 1970s, the physiologist Karloff advised that in congenital atrioventricular (AV) block in “normal hearts” an AV delay of 150 ms was needed according to physiological investigations. It is important to realize that during “right heart stimulation” we try to synchronize the left atrium and the left ventricle (LV).
