Splet05. jan. 2024 · By definition, a Q wave on the electrocardiogram (ECG) is an initially negative deflection of the QRS complex. Technically, a Q wave indicates that the net direction of early ventricular depolarization (QRS) electrical forces projects toward the negative pole of the lead axis in question.

"SpletS waves are transverse waves, meaning that the direction of particle motion of a S wave is perpendicular to the direction of wave propagation, and the main restoring force comes from shear stress. [2] Therefore, S waves cannot propagate in liquids [3] with zero (or very low) viscosity; however, they may propagate in liquids with high viscosity. " - S waves on ecg
