EKG, ECG Latest 2023 Already Graded A

EKG, ECG Latest 2023 Already Graded A AV node nodule of tissue in the right atrium that delays the electrical impulse just slightly to let ventricles fill with blood p wave Atrial depolarization st segement period of time between, the end of ventricular depolarization and the beginning of ventricular repolarization QRS complex ventricular depolarization Purkinje Fibers causes ventricles to contract, also produces the ECG waveform PR interval time interval from atrial contraction to ventricular contraction J point used to measure QRS complex, located at the end of the S wave T wave Indicates ventricular repolarization Bundle of His transfers the electrical impulse to the Bundle Branches R to R interval Length of time between one R wave and the next R wave is used to measure the heart rate Polarization resting state, no electrical activity is occuring repolarization relaxation Bundle of Branches located in the interventricular septum SA node natural pacemaker of the heart U wave repolarization of purkinje fibers,and bundle of his QT Interval represents complete, ventricular depolarization and repolarization depolarization contraction What does the SA node pace the heart at? 60-100 bpm What are the two reasons the AV node delays the electricl impulse? so you dont get to much electrical impulses, atrial kick If the Av node acts like a pacemaker of the heart , what will it pace the heart at? 40-60 bpm In what pattern do the bundle branches contract the interventricular septum ? left to right What is another name for the baseline? Isoelectric How are the ventricles stimulated to contract? acting at the same time
