Pacemaker malfunction or non-physiological ventricular pacing?
Pacemaker manufacturers have developed new algorithms to preserve intrinsic conduction in order to reduce unnecessary stimulation and looking for physiological pacing. This case report highlights some of the new challenges related to these algorithms which include possible ECG misinterpretations and inaccurate programming leading to potential negative consequences.
