Chapter 4 Supraventricular Rythms II Abnormal conduction • Initiation of the heart beat occurs in the ventricles. • Impulse is spread through the myocardial cells via gap junctions. PVC (pg. 43) • • • • Early Wide (>100 ms) 1mm = 40 ms >2.5 boxes • Different morphology Uniform and “Multiform” (pg.44) • PVCs that look different in the same ECG lead. • Multifocal vs. Multiform. Compensatory Pause Vs. Interpolated PVC (pg.44-45) Bigeminy, Trigeminy, Quadregiminy (pg. 46) Couplets, Triplets, VTach (pg.46-47) • • • • Short, non-sustained, or self terminating (pg.47) Sustained V-Tach (> 30 seconds) Sustained=MI. Shock treatment, meds. Patient may be awake or no pulse. Torsades de pointes • • • • “Twisting of the Points” Looping or shifting of the ectopic beat. Differing appearance than VTach – not as lethal. Cause is electrolyte abnormalities (K+) or medication. • Usually begins with a prolonged QT, usually is not sustained for long periods. R on T PVC (pg. 48) • Why is this a big deal? Accelerated and Escape Ideoventricular Rythms • Wide QRS but rate <100. • Pacemakers above AV Node have failed. Not PVCs. Not early beats but escape beats. Very slow HR. Poor Q. Ventricular Fibrillation (Pg. 50-51) • Numerous, unorganized, chaotic, rapid depolarizing of the ventricles. • No Pulse, no Q. Coarse vs. Fine Agonal Vs. Asystole (pg. 50-51) • Agonal – very slow rhythm that proceeds death. Differing pacemakers. • Asystole – The absence of electrical activity. No pulse, no Q. Flat line. – Be aware of leads coming off.
