Thus, the SA node is firing regularly causing regular P to P waves but either bundle of his or bundle branches are not receiving the action potential every time causing skipped QRS complexes. Slight variations in rhythm regularity may be noted with the respiratory cycle. Electrolyte imbalances can cause an increase in PVCs, so I like to have all of this information before I call the physician. The actual cause of Afib is unknown but research suggests many risk factors that are commonly seen with patients with Afib. Dopamine Epinephrine Transcutaneous pacing should be used if the patient is exhibiting signs and symptoms of poor profusion.
