TABLE 3-10 ■ Selected Heart Rates and Rhythms n i
Cardiac rhythms may be classified as regular or irregular. When rhythms are irregular or rates are fast or slow, an ECG is required to identify the origin of the beats (sinus node, AV node, atrium, or ventricle) and the pattern of conduction. Note that with AV (atrioventricular) block, arrhythmias may have a fast, normal, or slow ventricular rate.
