NUR 217 Test 2 (Graded A+ already)

Elements of a cardiac Waveform correct answers P wave, QRS complex, ST segment, T wave P wave correct answers atrial depolarization (its contracting), atria is squeezing. QRS complex correct answers ventricular depolarization T wave correct answers ventricular repolarization rhythm strip correct answers all about timing. one tiny square is 1 mm in length and represents 0.04 sec. 5 of them equals 0.20 sec. Then every 5 boxes is 1 second. Avg rhythm strip is 6 second. First you want to figure out the HR (count the R wave). then if there is a P for every QRS Normal Sinus Rhythm correct answers heart rhythm originating in the sinoatrial node with a resting rate of 60 to 100 beats per minute. NORMAL. A caliber correct answers used to measure the widths of each wave. At R wave. Sinus Bradycardia correct answers 60 bpm, you know its sinus if there is a P for every QRS. Patient might have dizziness, chest pain, confusion due to lack of 02, or we can give meds: Atropine, Sinus Tachycardia correct answers 100 bpm, they can pass out. First find out whats causing a fast HR (stress, meds). Use beta blockers (end in lol) to slow down HR A fibrillation correct answers Multiple ectopic pacemakers in the atria discharge at a very rapid rate B. The impulses are so rapid it causes the atria to quiver instead of contracting regularly C. If left untreated may cause thrombus formation due to blood pooling in the atria from inadequate contractions Commonly associated with CH If not tolerated will show signs of decreased cardiac output Atrial Flutter correct answers very rapid, atrial muscles respond and causes flutter waves. Looks like a saw tooth, More P waves than QRS. feels like a regular rhythm. Atrial wave is 2x more that QRS (ventricles). can have a dec cardiac output, we wanna fix that. We can give Digoxin Atrial flutter vs AFib correct answers Atrial flutter and atrial fibrillation are both abnormal heart rhythms. ... In atrial fibrillation, the atria beat irregularly. In atrial flutter, the atria beat regularly, but faster than usual and more often than the ventricles, so you may have four atrial beats to every one ventricular beat. premature ventricular contraction (PVC) correct answers the ventricles are stimulated by a different part of the hearts electrical system. Sometimes benign. When they start to form a
