Therapy (Tx)

Premature Atrial Contraction Ectopic beat produced by the Atria QRS .10> or absent Early P waves Emotional stress, CHF, myocardial ischemia or injury, mental & physical fatigue, atrial enlarged, digoxin toxicity, Hypokalemia, excessive intake of nicotine, caffeine, alcohol Usually treatment is not required. EKG

Premature Ventricle Contraction Irritable focus within the ventricles P waves absent NO PR interval QRS .12< bizarre T’s decreased May also be asymptomatic or complain of a racing heart. EKG Couplets = 2 PVC’s Bigeminy q other is PVC Trigeminy q 3rd beat is a PVC Can occur in healthy patients Hypoxia, stress, increase in catecholamines, stimulants, electrolyte imbalance, digoxin toxicity, medications Anti- dysrhythmic Adequate 02 Relief of pain

Ectopic atrial rhythm in which an irritable site depolarizes regularly at a rapid rate. 250-450 beats/minute AV is the gate keeper & allows some impulses NO P’s QRS .10> Flutter-QRS-flutter-QRS
