This phenomenon is called the ______________ ___________ - atrial kick deflection representing atrial depolarization the electrical impulse is consistently generated from the SA node - P wave measures the beginning of the P wave to the end of the PR segment it represents the time required for atrial depolarization, the impulse delay in the AV node, and the travel time to the purkinje fibers normally measures 0.12-0.20 second - PR interval each small block on the ECG equals _______ second - 0.04 five small blocks on the ECG tracing equal ___________ second - 0.20 T/F five *large blocks* on the ECG tracing equal one second - true ___________ large blocks on the ECG tracing equals 6 seconds - 30 The QRS duration represents the time required for depolarization for both ventricles it normally measures from __________________ second - 0.04- 0.12
