HR 150-250 typically 3. PR interval difficult to measure 4. QRS complexes at a normal rhythm and distance apart 5. often paroxysmal what does paroxysmal mean? - CORRECT ANSWER has a sudden onset and sudden termination how is supraventricular tachycardia different from atrial fibrillation? - CORRECT ANSWER the QRS complexes are at a regular rhythm and distance apart what is the common treatment of supraventricular tachycardia - CORRECT ANSWER adenosine: 6 mg followed by 12 mg administered via stop cock method through large vein: needs to be slammed in and then flushed 1-2 screens of asystole is expected: prepare patient for "feelings of impending doom" what patient population is supraventricular tachycardia common in? - CORRECT ANSWER adolescents ablation may be a typical intervention what is the most common irregular heart rhythm? - CORRECT ANSWER atrial fibrillation where does the impulse originate from in atrial fibrillation? - CORRECT ANSWER atria what is occurring in atrial fibrillation? - CORRECT ANSWER many impulses begin and spread through the aorta and complete for a chance to travel through the AV node, causing a rapid and disorganized heartbeat what is the typical atrial heart rate in a-fib? - CORRECT ANSWER 300-600 BPM what node limits the number of impulses that are allowed to travel to the ventricles? - CORRECT ANSWER the AV node in a rhythm with unidentifiable P and T waves and irregularity present, what rhythm should first be considered? - CORRECT ANSWER a-fib what two questions should be asked when a-fib is present? - CORRECT ANSWER is it controlled or uncontrolled? is the patient symptomatic? what assessments should be done when a-fib is present? - CORRECT ANSWER HR BP electrolytes (K, Mg, Ca) oxygenation status dizziness anxiety CO low, resulting in low BP? what is considered controlled a-fib? - CORRECT ANSWER HR under 100 what treatments are typically done for a-fib? - CORRECT ANSWER beta blockers ca-channel blockers (most common IV cardizem if uncontrolled) amiodarone (can do IV or PO) what is a major concern with a-fib? - CORRECT ANSWER clots what secondary issues can occur with cardizem? - CORRECT ANSWER it is titrated to decrease HR in emergent a-fib situations, but secondary BP hypotension can occur what can the use of amiodarone impact? - CORRECT ANSWER liver function a client developed atrial fibrillation, which a ventricular rate of 150 beats/min.
