Inherent Cardiac Rates The frequency of impulse formation attributed to a given pacemaker location within the heart. - sinus node, 60 to 100 beats/min - atrioventricular junction, 40 to 60beats/min - ventricle, 15 to 40 beats/min. Rate: 6 Second Method The second method can be used with an irregular rhythm to estimate the rate. Count the number of R waves in a 6 second strip and multiply by 10 Regularity Determining regularity is the second step of analyzing an ECG rhythm. Irregular rhythms are considered abnormal and can be caused by a variety of conditions. If the distance of the R-R intervals or P-P intervals is the same, the rhythm is regular – if the distance differs, the rhythm is irregular. Regularity: Calipers P Waves • Are they present? • Upright or Inverted? • The P Wave represents Atrial Depolarization. • Absence of a P wave indicates that there is no conduction witin the atria • Absent or inverted P Waves with an associated narrow QRS complex may indicate a Junctional origin Abnormal PR Interval First-Degree AV Block PS PETG TESTS SERIES ESTE TTI STL eb Ea LE PaEaetErepiEiseaEieT ipa a QRS Duration The normal duration (interval) of the QRS complex is between 0.08 and 0.10 seconds — that is, 80 and 100 milliseconds. When the duration is between 0.10 and0.12 seconds, it is intermediate or slightly prolonged. A QRS duration of greater than 0.12 seconds is considered abnormal.
