![]() ![]() ![]() Failure of the SA node to discharge an impulseĢ. Characterized by an irregular pause in the regular rhythmġ. Clinical Presentation – no problems associated with rhythmĪ. Seen most often in children and young adultsĢ. ![]() Inspiration causes slight increase in rate and exhalation causes a slight decrease in rate due to vagal tone during the different phases of respirationģ. Characterized by slightly irregular rhythmĢ. Medical treatment may include atropine or pacemakerĪ. Treated only if accompanied by symptoms of hypoperfusion, such as dizziness, chest pain, changes in LOCĢ. Clinical Presentation – dependent on the rate and patient tolerance of the rateġ. Characterized by heart rate less than 60Ĭ. Treatment – directed at the underlying causeĪ. Clinical Presentation – dependent on the rate and patient tolerance of the rateĮ. Causes: fever, any type of hypovolemia such as dehydration or blood lossĭ. Characterized by heart rate greater than 100ī. Treatment – no treatment generally associated with this rhythmĪ. Clinical Presentation – no problems typically associated with rhythmĭ. P wave: only one precedes each QRS, all have same size, shape and deflectionĬ. Is the standard against which all other rhythms are comparedĤ. Records the impulse originating from the sinus node and follows the path to the atria, AV junction, and through the bundle of His, to the bundle branches and on to the Purkinje fibersĪ. ![]()
