Atrial Arrhythmias
Question | Answer |
---|---|
An electrical impulse that originates outside of the sinoatrial (SA)node is called an | ectopic beat |
Ectopic means | out of place |
Heart rate(HR) is usually associated with the ventricular rate which is represented by the | R waves |
In Wandering(atrial)pacemaker(WAP)the rhythm is | 1.)Usually irregular 2.)The heart rate(HR) is usually 60-100 Beats Per Minute(bpm) 3.)The morphology of the p wave changes 4.)The PRI(PR interval) is usually 0.12-0.20 seconds 5.)The QRS complex is 0.12 seconds or less |
In Premature Atrial Contraction(S){PAC(s)}may be | 1.)Regular or irregular 2.)The Premature Atrial Contraction(s){PAC(s)} comes in early 3.)The morphology of the P wave of the premature Atrial Contractions{PAC(s)} changes 4.)The PRI (PR interval) is usually 0.12 to 0.20 seconds |
An early or premature beat is an indication of | cardiac irritability |
Common causes of cardiac irritability include: | 1.)Tobacco 2.)Caffeine 3.)Alcohol(ETOH) |
In Atrial Tachycardia(AT)the rhythm is: | 1.)Regular 2.)The Heart Rate(HR)is USUALLY 160 to 250 Beats Per Minute(bpm) 3.)An atrial (upright)P wave may be seen before every QRS complex unless the Heart Rate (HR) is too fast 4.)The PRI(PR interval) is usually 0.12 to 0.20 seconds |
The witnessed onset of Atrial Tachycardia(AT) is called | Paroxysmal Atrial Tachycardia(PAT) |
In Atrial Flutter(AF) the rhythm can be: | 1.)Regular or irregular 2.)The Heart Rate(HR) can vary 3.)There are more P waves then QRS complexes and the P waves will have a "sawtooth" morphology 4.)The PRI(PR interval) is not measured 5.)The QRS complex is 0.12 seconds or less |
The "sawtooth" P waves are referred to as | "flutter waves" or "F waves" |
If the number of "flutter waves" is constant, the rhythm will be | regular |
If the number if "flutter waves" is not constant,the rhythm will be | irregular |
If there are 3 "flutter waves" between QRS complexes, the rhythm is called | atrial flutter with a 3 to 1 block |
If there are 4 "flutter waves" between QRS complexes, the rhythm is called | atrial flutter with a 4 to 1 block |
If the number of "flutter waves: varies between QRS complexes, the rhythm is called | atrial flutter with a variable block |
In Atrial FIBrillation(A-Fib)the rhythm is: | 1.)Inherently irregular 2.)The P waves are indiscernible 3.)The PRI (PR interval)is not measured 4.)The QRS is 0.12 seconds or less |
Inherently means | naturally |
If the ventricular rate of Atrial FIBrillation (A-Fib)is below 60 Beats Per Minute(bpm)the rhythm is called | Atrial FiBrillation(A-Fib)with a slow ventricular response |
If the ventricular rate in Atrial FIBrillation(A-Fib)is between 60 and 100 Beats Per Minute(bpm)the rhythm is called | Atrial FIBrillation(A-Fib)with a controlled ventricular response |
If the ventricular rate in Atrial FIBrillation(A-Fib)is above 100 Beats Per Minute(bpm)the rhythm is called | Atrial FIBrillation(A-Fib) with a Rapid Ventricular Response(RVR) |
