…and ECG electrodes . An electrode is a conductive pad that is attached to the skin and enables the recording of electrical currents. An ECG lead…

…The atrial impulse must pass through the atrioventricular node, which delays the impulse due to its slow conduction, before the impulse may reach the ventricles…

…efficiency of the pumping function. The primary ECG manifestations of conduction defects are prolonged QRS complexes and altered QRS appearance. These concepts will be discussed…

…participants with baseline ECG examinations. Individuals with nonspecific intraventricular conduction delays were at particularly high risk of death due to arrhythmias. Note that other causes…

…potential occurs. If any component of the ventricular conduction system has not fully repolarized by the time the next impulse reaches the ventricles, the impulse…
