If the R and S-waves are of equal size it means depolarisation is travelling at exactly 90 It can also be a normal finding in very tall individuals. , drugs, ischemia, electrolyte imbalances, infections, and pulmonary disease) can affect the ECG. It is characterised by the presence of correctly oriented P waves on the electrocardiogram (ECG). ECG Interpretation in Myocardial Ischemia Approach to ECG Interpretation. Atrial and ventricular depolarization and repolarization are represented on the ECG as a series of waves: the P wave followed by the QRS complex and the T wave. Share to: Answered. Main Menu. Normal: heart rate dependent Sinus rhythm means a normal heart beat, both with respect to the heart rate and rhythm. In a normal ECG, there's three This means that the ventricles are relaxed and under less pressure. Each QRS complex is preceded by a normal P wave. What do these two results mean?
