WebMar 11, 2024 · The various components of an electrocardiogram (ECG) (ie, P wave, QRS complex, and T wave) have different and distinct amplitudes and frequencies. ... Normally, in lead V1, there is a small R wave with a deep S wave; the R-wave amplitude should increase in size with the transition zone, normally in leads V2 to V4. Poor or late R-wave ... WebThe S wave is deepest in the right precordial leads, usually in lead V 2. The S wave amplitude decreases as the left precordium is approached. ...

WebLeft ventricular hypertrophy (LVH): Markedly increased LV voltages: huge precordial R and S waves that overlap with the adjacent leads (SV2 + RV6 >> 35 mm). R-wave peak time > 50 ms in V5-6 with associated QRS … WebJan 31, 2024 · The electrical impulse then reaches the ventricles. This can be seen in the Q, R and S waves of the ECG, which is called the QRS complex. The ventricles contract. Then the T wave shows that the electrical impulse has stopped spreading, and the ventricles relax once again. Heart diseases and irregular heartbeats can be detected in ECGs.
