What is a new way we can search for PACs?
Use trace view
What is the most common rhythm?
Normal Sinus Rhythm
Pacing
When a patient is having severe brady at 30 BPM, why is the doctor worried?
Various reasons, it could be medication problems, if it happens during wake hours, could be a sign of heart failure, low enough where pauses could be deadly.
What is a pace maker?
Wouldn't you like to know.
What is a good key bind for when you need to add a AFL episode inside a long AF episode?
Alt+W
What are the most clinically accurate atrial rates for AT w VC and AFL?
AT w VC 100-220 and AFL 221-350
What is most common to see with the indication "Persistent Atrial Fibrillation"?
AF or AFL in the scan either 100% or paroxysmal.
When a patient is having 5+ second pauses and they are 27 years old, why is the doctor so worried?
Abnormal at this age, 5-6 seconds without blood flow it typically how long it takes to lose consciousness, and people who have long pauses are a fall risk.
What is the most normal rate for a pacemaker to pace at?
60 BPM
What are some other ways we can look for AF and AFL min and max?
Click and edit beat method, highlight and use arrows method, and trace view moving 8 second highlight.
What are the 3 major differences between AT w VC and AFL?
Atrial rate, generated vs reentry, isoelectric line lacking/present
When I see "other supraventricular tachycardia, supraventricular tachycardia unspecified" in a kid what do I see often?
AVNRT, AT, AVRT
When a patient who is 73 having new onset 3rd degree, what might the patient be feeling?
Light headiness, Dizziness, Dyspnea, Syncope, Collapse, palpitations, tiredness.
What is the most common cause of failure to capture?
Weak cardiac cells getting weaker over time, and a failing pacemaker battery.
HR range bin looking at VEB rates and JEB rates, HR range bin looking at half your avg HR, Min HR bin, flat sections of R-R plot, and by double checking around your 2nd degree type 1 with JEBs on trace view.
What are 5 steps to tell if it's AF with aberration and not VT?
1. How frequent is it?
2. Ashman's?
3. Does it match PVC forms?
4. Does it occur only at high rates?
5. Does the patient have any indications or precursors? (BBB, RVH, RBBB)
What am I likely to see in the lower heart rates when I have the indication hypotension?
U wave
Why might a doctor be concerned about a patient admitted with persistent 150+ V Tach for 1 hour?
Can lead into vfib or TDP, has the ability to create scar tissue increasing the problem, lower blood output (also oxygen), over work ventricles and create hypertrophy.
When is a pacemaker most commonly implanted?
When the patient needs CRT or their atrium to beat in tandem with their ventricle (3rd degree or IVR due to ablation of AV node), and very low sustained HRs in waking hours.
What are two methods we used to more quickly find ectopy in noisy scans?
What are the most likely time to have defib spikes?
At the end of very fast atrial ectopy that has been long sustained, within 30 minutes of sustained fast ventricular tachycardia, when VF/TDP is present.
If I see the indication WPW what am I commonly going to see in the study?
AVRT
Why is an AFL MDN 220+ for 1 minute so dangerous for a patient?
Heart is overworking the muscle which gives it a higher chance to give up, lowered blood output due to hr being too high.
When is an AICD most commonly implanted?
In cases with frequent sustained VTACH, history of TDP/VFIB episodes, or very fast sustained supraventricular tachycardia.
