ECG interpretation: Characteristics of the normal ECG (P-wave, …
At the heart of ECG interpretation lies the ability to determine whether the ECG waves and intervals are normal. This chapter will focus on the ECG waves in terms of morphology (appearance), durations and intervals.
Understanding an ECG | ECG Interpretation - Geeky Medics
2011年3月5日 · In healthy individuals, there should be a P wave preceding each QRS complex. The PR interval begins at the start of the P wave and ends at the beginning of the Q wave. It represents the time for electrical activity to move between the atria and the ventricles. The QRS complex represents the depolarisation of the ventricles.

Electrocardiogram (EKG, ECG) - CV Physiology
The different waves that comprise the ECG represent the sequence of depolarization and repolarization of the atria and ventricles. The ECG is recorded at a speed of 25 mm/sec (5 large squares/sec), and the voltages are calibrated so that 1 mV …
Overview of the ECG Waves, Deflections, Intervals, Durations
Below follows a brief summary of the ECG waves, their appearance, terminology, physiological background and interpretation. Figure 1. The classical ECG curve with its most common waveforms. Important intervals and points of measurement are depicted. ECG interpretation requires knowledge of these waves and intervals.
