Dysrhythmias (Including EKG Strips) Relias Dysrhythmia Basic Test Answers 2023 Dysrhythmia – Basic A ( A+ GRADED 100% VERIFIED) Normal Sinus Rhythm - ANS Refers to a rhythm that originates in the SA node @ a rate of 60-100 BPM and follows normal conduction pattern of the cardiac cycle. Sinus Bradycardia - ANS The conduction pathway is the same as that in sinus rhythm but the SA node fires @ a rate of less than 60 BPM. May be normal in athletes. Symptomatic Sinus Bradycadia S/S - ANS Pale, cool skin, hypotension, weakness, angina, dizziness or syncope, confusion or disorientation, and shortness of breath. Symptomatic Sinus Bradycardia Tx - ANS Admin of atropine, or pacemaker therapy. If due to drugs; must be held, discontinued, or dosages reduced. Sinus Tachycardia - ANS The conduction pathway is the same as that in sinus rhythm. The discharge rate from the sinus node increases because of vagal inhibition or sympathetic stimulation. the sinus rate is 101-200 BPM. Sinus Tachycardia S/S - ANS Dizziness, dyspnea, and hypotension due to decreased CO. Increased O2 consumption due to increased HR. Angina or an increase in infarction size may accompany this disorder in pts with CAD or AMI Sinus Tachycardia Tx - ANS The underlying cause determines treatment, eg.) pain management if d/t pain. In stable pts vagal manuevers can be attempted. Beta-adrenergic blockers Atrial Flutter - ANS An atrial tachydysrhythmia identified by recurring, regular, sawtooth-shaped flutter waves that originate from a single ectopic focus in the right atrium, less commonly, can occur in left atrium. Atrial Flutter S/S - ANS High venticular rate; loss of atrial 'kick'. Decreased CO, HF: esp in pts with underlying heart disease, and increased risk of stroke. Atrial Flutter Tx - ANS Coumadin, slow ventricular response by increasing AV block, calcium channel blockers, beta-adrenergic blockers, electrical cardioversion, antidysrhythmia meds, and radiofrequency catheter ablation. Atrial Fibrillation - ANS Characterized by a total disorganization of atrial electrical activity due to multiple ectopic foci resulting in loss of effective atrial contraction. May be paroxysmal or persistant (+7 days). Most common dysrhythmia.
