A 46-year-old homeless man was found confused on a city street during a very cold day in January. EMTs are called, and upon arrival to the emergency department, the man is still confused. Body ...

These ECG voltage attenuations are of extracardiac mechanism, and impact the amplitude of QRS complexes, P-waves, and T-waves, occasionally resulting also in shortening of the QRS complex and QT ...

There is no associated P wave, although an independent normal P ... sinus depolarization would suppress it 2,3. Figure 2: An ECG obtained from a beagle dog 21 days later, showing six rhythm ...

Positive and negative peaked T waves with high amplitude were detectable in the preclinical 12-lead ECG. Additionally, a first-degree AV block was present (P waves merging with preceding T waves).
