True about U waves is all except
It is due to Delayed repolarisation of Purkinje fibres
Maximum normal amplitude of the U wave is 1-2 mm
The U wave normally goes in the opposite direction as the T wave
U waves generally become visible when the hea rate falls below 65 bpm
The U wave normally goes in the same direction as the T waveU -wave size is inversely propoional to hea rate: the U wave grows bigger as the hea rate slows downU waves generally become visible when the hea rate falls below 65 bpm
