Figure caption, This displacement-distance graph is how you would measure a wavelength of a wave Frequency – the number of complete vibrations in one second. This is the same as the number of ...

1 Hz is one wave per second. It is common for kilohertz (kHz), megahertz (MHz) and gigahertz (GHz) to be used when waves have very high frequencies. A displacement-distance graph is a snapshot of ...

V5 and V6 ST and T wave displacement opposite to the major deflection of the QRS complex A simple way to diagnose a left bundle branch in an ECG with a widened QRS complex (> 120 ms) would be to ...
