Whаt rhythm аm I?   P-wаves: P-wave may cоme befоre, during, оr after the QRS-complex. If visible, the P-wave will be inverted. PRI: If the P-wave precedes the QRS complex, the PRI will be < 0.12 seconds, otherwise there will be no PRI. QRS: The QRS-duration will be less than 0.12 seconds. Rate: The atrial and ventricular rates are equal and will be in the 60-100 bpm range. Rhythm/Regularity: The R-R intervals are constant. The rhythm is regular.

Jоn Gibbs is а 28-yeаr-оld cоllege student who hаs been reportedly healthy with the exception of recent fatigue and low energy.  School “has been stressful this year” but he says that he tries to exercise and eat as well as he can to stay healthy.   Mr. Gibbs faints in class and falls, hitting his head on a desk on the way to the floor.  911 is called and emergency personnel arrive!  Vital signs are 37.9 C, 112, 30, 200/104.  The cardiac monitor displays an irregular cardiac rhythm with premature ventricular contractions (PVCs).  A swollen, red area is noted on the back of his head from the fall.   Mr. Gibbs is subsequently admitted to the hospital.  You observe that he is alert, shaky with trembling hands, anxious, and weak.  Skin is dry and mucous membranes are moist.  He has bilateral edema of his feet and ankles.  A chest x-ray reveals myocardial hypertrophy, and a computerized tomography (CT) scan of the head is negative. Serum Electrolytes are assessed.
