Are these Hyperacute T-waves?

I received this ECG in a text message, with the message:" Hey, these look like hyperacute T waves to me, what do you think?  It ’s an intubated septic nursing home patient. "  " Here is her old ECG: "What do you think?Here is my response:" There is something wrong with this ECG.  It might be another case of pulse tapping artifact. Change the location of the limb Electrodes and repeat the EKG. All leads except lead I look bizarre. "So he repeated the ECG after moving the limb lead electrodes:Much less bizarre appearing, and without the suggestion of hyperacute T-wavesPulse Tapping ArtifactEver since learning about " Pulse Tapping Artifact, " I have begun seeing it more.  It may be that it is much more common than we think but just not recognized.We have posted Pulse Tapping Artifact 3 times before:I was shown this ECG without any information. What do you think?Acute chest pain and a bizarre ECGBizarre (Hyperacute??) T-wavesExplanationAll leads are derived from 3 bipolar electrodes and one unipolar electrode.Leads I, II, and III depend on bipolar leads voltage differences:--Lead I uses the right and left arm--Lead II uses the right arm and the leg--Lead III uses the left arm and the leg.--The Wilson (or Goldberger) Central Terminal is used to produce the augmented (a) leads:aVR, aVL, aVF.The voltages are calculated as follows (Thanks to Ken Grauer for sending these):I = L - RII = F - RIII = F - LaVR = R - (...
