Pacemaker ECGPacemaker ECG is a tracing featuring characteristic pacing spikes and paced complexes that occur in response to a stimulus...
Atrial pacingAtrial pacing (AAI mode) is a pacemaker operating mode in which the lead is placed in the right atrium and pulses are delivered only to...
Ventricular pacingVentricular pacing is a QRS complex paced by an artificial pacemaker, where ventricular depolarization begins from the lead rather than from...
Dual-chamber pacingDual-chamber pacing (DDD mode) is a pacing mode in which both sensing and pacing leads operate in both the atrium and the ventricle.
Pacemaker failure to capturePacemaker failure to capture occurs when the electrical stimulus of the pacemaker fails to induce myocardial depolarization.
UndersensingUndersensing is the inability of the pacemaker to recognize intrinsic electrical activity of the atrium or ventricle.
OversensingOversensing is the erroneous detection by the device of signals that should not be counted as events in that chamber, such as myopotentials,...
Pacemaker-mediated tachycardiaPacemaker-mediated tachycardia (PMT) is a functional endless-loop tachycardia in patients with a pacemaker that features...
Pacemaker malfunctionPacemaker malfunction is a failure in pacemaker operation where the stimulus does not trigger contraction or fails to recognize the intrinsic rhythm...
Pacemaker syndromePacemaker syndrome is a symptom complex arising from the loss of atrioventricular synchrony in a patient with...
NBG pacemaker codeThe NBG pacemaker code is a standardized letter designation for pacemaker operating modes (pacemaker code) adopted by a joint nomenclature committee.
Cardiac resynchronization therapy ECGCardiac resynchronization therapy (CRT) ECG shows biventricular pacing, characterized by simultaneous or near-simultaneous activation of the left and right...
