The advances in know-how surrounding pacemakers has ended in an inevitable raise within the complexity of ECG interpretation of pacemaker-generated rhythms. Simplified Interpretation of Pacemaker ECGs deals a step by step description of pacemaker ECG interpretations. a useful source for cardiologists, citizens, apartment officials, normal clinicians, and nurse practitioners, this article includes:a step by step description of pacemaker ECG interpretations a quick refresher path on easy ECG interpretation with an outline of the conduction procedure of the center a overview of the linked to pacing a proof and dialogue of the sensing and pacing functionality assurance of the commonest pacing modalities and weird pacing events a sequence of case experiences that assemble all the details discovered and supply the reader with a self-assessment of themes to study ECGs, charts, and illustrations

The voltage source has a positive and a negative terminal which, when connected to both ends of the resistor, can cause current to flow across the circuit. The relationship between the voltage, current, and resistance may then be described by the equation, V (voltage) = I (current; in Amps) * R (resistance). ’’ For example, if a circuit has a voltage of 10 V and resistance of 5 ⍀, then by Ohm’s law the current that may flow in the circuit is 2 A (10 V/5 ⍀). A different circuit can be created by connecting another resistor in parallel to the first.
The pacemaker is more sensitive). , the pacemaker is less sensitive). 5 mV on an atrial EGM (AEGM) will allow a pacemaker to sense the P wave and ignore the far-field R wave. If the sensitivity setting is increased to 10 mV (pacemaker made less sensitive), then neither the P or R wave will be sensed because each is not tall enough. 25 mV (pacemaker made more sensitive) then both P and R wave may be sensed because both are tall enough. The R wave amplitude on a ventricular EGM (VEGM) is typically greater than the P wave amplitude on an AEGM, and is on the order of 5 to 25 mV.
This is because it may be wider in duration and has a left bundle branch block (LBBB) morphology. Why does it have an LBBB morphology? Recall that the tip of the ventricular pacing lead most commonly sits in the right ventricle, which is close to the right bundle branch of the native conduction system. Therefore, with ventricular pacing the left bundle branch gets activated later and produces an LBBB complex. Should a ventricular captured beat display a right bundle branch block (RBBB) morphology, this may be cause for concern.
