Finally, as the potassium continues to rise, the p waves are lost, and the QRS widens further leading to a sine wave pattern finding on EKG. The EKG in photo #1 represents this sine wave ...

Using a copy of [SPICE] a free circuit simulation application, I have created several sine wave sources and summed them together. Seen here, the waves combine into a square wave with it looking ...

You must treat the hyperkalemia first. Absence of the P waves and eventually a “sine wave” pattern, as seen below, which is frequently a fatal rhythm CLINICAL PEARL: Giving intravenous calcium ...
