the interval from the beginning of the P wave to the beginning of the QRS complex on an electrocardiogram. It represents the atrioventricular conduction time, which normally is between 0.12 and 0.20 second.
In the electrocardiogram, the period between the onset of the P wave and the beginning of the QRS complex.
See also: interval
the space between two objects or parts; the lapse of time between two events. In statistical terms, the numerical distance between two values.
atrioventricular interval, A-V interval
see P-R interval (below).
the time between the apex beat and arterial pulsation.
in electrocardiography, the time between the onset of the P wave (atrial activity) and the QRS complex (ventricular activity).
QRST interval, Q-T interval
the duration of ventricular electrical activity.
in electrocardiography, refers to the P and R waves.
the period from the beginning of the P wave to the beginning of the QRS complex.
the isoelectric tracing that follows the P wave and ends with the deflection of the Q wave. It represents the delay of the electrical impulse at the atrioventricular node.
