17.4B: Electrocardiogram and Correlation of ECG Waves with Systole

WebbThe P Wave: The P wave of an electrocardiogram (EKG or ECG) represents the depolarization (i.e., contraction) of the atrial muscles. The atria are the top two chambers of the heart. When these muscles contract, the atria pump blood into the bottom two chambers of the heart which are the ventricles. Answer and Explanation: 1 WebbThe P-wave, PR interval and PR segment ECG interpretation starts with assessment of the P-wave and PR interval. The P-wave is generated by depolarization (activation, contraction) of the atria. The PR interval is the interval between the start of the P-wave and the start of the QRS complex.

WebbThe P wave represents the wave of depolarization that spreads from the SA node throughout the atria and is usually 0.08 to 0.10 seconds (80-100 ms) in duration. The … WebbQ waves. A normal ECG has only very small Q waves. A downward deflection immediately following a P wave that is wider than two small squares or greater in height than a third of the subsequent R wave is significant: such Q waves can represent previous infarction (see Figure 11, previous page).

Webb23 jan. 2010 · P waves represent depolarization of the atria. QRS represents the depolarization of the ventricles. T wave is due to ventricular repolarization. The repolarization wave of the atria is not usually visible on the surface electrocardiogram. If present, it is known as the Ta wave. The extent of Ta wave includes the PR segment, …

WebbThe QRS complex may be R alone, QS (no R), QR (no S), RS (no Q), or RSR ′, depending on the ECG lead, vector, and presence of heart disorders. Normally, the QRS interval is 0.07 to 0.10 second.
