3rd Degree Heart Block (Complete Heart Block) {Ans: Impulse is completely blocked with each beat between the SA node and AV node. This results in the atria beating under the control of the SA node pacemaker independently of the ventricles beating under the control of the AV node pacemaker or ventricle pacemaker of the bundle branches/Purkinje fibers. • Rhythm: Atrial is regular and Ventricular is regular, BUT there is no relationship between the P's and QRS's • Rate: Atrial (60-100) • Ventricular (40-60 - AV node) (20-40 - ventricle) • P waves: Normal in size and shape • PRI: There is no true PRI to measure (N/A) • QRS: May be within normal limits or wide. If normal, AV node is pacemaker ["CHB @ AV level"]; If wide, ventricle (bundle branches/Purkinje fibers) is pacemaker ["CHB @ BB level"].}Atrial Flutter {Ans: The impulse originates in the Atria • The Atrial rate is 250-350 and rhythm regular • The PRI is not measurable (N/A) - Characteristic saw-tooth wave. • The Ventricular rhythm may be regular or irregular • QRS within normal limits • If the Ventricular rate is < 100 it is controlled Atrial Flutter; if the Ventricular rate is
