  • the deflection waves in an ecg tracing include?
  • Another difficult question.=/ ugh. Please help me?
  • Which of the following correlations between cardiac contractions and ECG waves is correct? ?
  • 10 POINTS! Please help me. thank you?
  • Atrial and ventricular contraction?

      The wave represents atrial depolarization during normal atrial depolarization and spreads from the sa node and contraction.
      The sa node and contraction.

      B. atrial depolarization and contraction

      Atrial repolarization is Ta wave, usually not seen

      Ventricular depolarization is QRS
      Ventricular repolarisation is T wave
