ECG Definers Flashcards
1 (VT):
2 Definer:
3 note fusion P waves:
1= usually reentry prob
2= 100BPM or >, wide QRS
3= P waves trying to insert self in to VT
If the R is far from the P, then you have a:
FIRST DEGREE!
Longer, longer, longer, drop, then you have a
= WENCKEBACH!
If some Ps don’t get through, then you have a:
= MOBITZ II!
If Ps and Qs don’t agree, then you have a:
= THIRD DEGREE!

Junctional Bradycardia) Remember:
Definer:
1= AV inherit firing rate 40-60 so <40BPM AV Brady
2= <40BPM, REG/ rhythm, AV P waves, QRS WNL (can be wide)
(PVC) Bigeminy:
Trigeminy
Quadgeminy
= 2rd beat uni/PVC regularly “boom PVC” (1:1 pattern)
= 3rd beat is uni/PVC regularly “boom boom PVC)
= 4rd beat is uni/PVC regularly “boom boom boom PVC” 2-3x
(PVC) Unifocal:
Multifocal:
= same fire site & shape
= dif fire spots & shape
Accelerated idiopathic (AIVR):
2 Definer:
1= SNS anxiety releasing EPI & NORepi
2= wide QRS, 41-100BPM, Reg/ Rhythm
Idiopathic, Ventricle Escape (IVR)
2 Definer:
1= AV slows downs so slow Bottom is faster & louder
2= QRS >3SB or 0.12secs w/ cadence & w/o P waves
Torsades De Pointes (TDP) Twisting of points
2 Definer:
1= most common polymorphic VT “teeter toter of de & re /polarization of ventricles” (twisting ribbon)
2= Changes in shape w/ size (note w/ change of conduction)
VF) ventricular Fib/quiver
2 Definer:
1= “death rattle”, never pulse,
2= Chaos, “wide QRSs”
Artificial Pacemaker) know:
Definers:
1= usually L upper chest adults & kids
2=Atrial line w/ P wave following, Ventricular line followed w/ QRS (wide QRS), AV sequential 1 line before the Ps & QRSs, Fail to shut down, Can fail to capture if leads displaced, Runaway pacemaker (Pacemaker running 190Bpm)
1 Premature Ventricular Contractions (PVC):
2 Definers:
1= >50% (Don’t + w/ HR) “Pissed off & shouting out”
2= Premature, Wide QRS, no P-wave
- 1st Degree AV Block) know:
- Definer:
1= “add to any rhythm” “gandolf slowly opening door(PRI)”
2= PRI: >than 0.20 seconds for every PRI & P-P cadence
- 2nd Degree Type I) AKA & Know:
- Definer:
1= “Morbitz 1”/“Wenckebach” rhythm & “AV turning off to fully down”
2= progressive longing PRI till drops beat then resets/starts over
- 3rd Degree AV Block) AKA & know
- Definer:
1= “Complete AV-Block/dissociation” (always TCPP on) “gandalf died”
2= No relations w/ Ps & QRSs & no same PRI (top & bottom dif)
- (A-Fib) know:
- Definer:
1= most common, only treated when >150BPM, more Js b/c more sites
2= No definite P waves, Totally Irregular
- Accelerated Junctional) Know by:
- Definer:
1= “Baby Tachy” faster than 60 not faster than 100
2= 61-100BPM, (from SNS & AV firing), Regular rhythm, AV P waves
Atrial Flutter) Know:
Definer:
1= “saw tooth Ps”, count bottom of points of flutters “3 to 1 block”
2= Sawtooth Ps w/ regular rhythm
Junctional rhythms) aka know by:
Definer:
1= junctional escape: “pick up workload b/c something failed”
2= AV P waves & AV node rate 40-60BPM, Regular rhythm
1Paroxysmal Supraventricular Tachycardia (PSVT)
2 Definer
1= “ SVT sudden start & stop” not associated w/ underlying Cdisease
2= same as SVT but sudden onset/ends abruptly
1Supraventricular Tachycardia (SVT)
2Rules:
3 Treat:
1= AV going NASCAR
2= No P waves, 150-250 BPM, regular rhythm
3= vagal maneuver, adenosine, unstable= cables (@50-100J) go to max)
1w/ PAC:
2Definer:
1= Premature Atrial Contractions “w/”
2= dif P wave shape w/ premature depolarization
2nd-Degree Type 2 AV block) names:
Mobitz 2 or intranodal AKA “2:1 block” rhythm
2nd-Degree Type I AV block) names
Mobitz 1 or Wenckebach
Rhythm initiated by SA node should have a rate between:
Sinus Tachycardia has a heart rate of:
Sinus Bradycardia has a heart rate of:
= 60-100 beats per minute
= 101 & >BPM
= 59 &<BPM
1 Asystole:
2 Definer:
1= no activity (most common PEDIS arrest)
2= NONE, NONE, NONE
AV node Heart blocks are
blocks in AV node partial or complete
“Putting a rock or pebble on a cable”
“AV node P waves” morphology:
= inverted before QRS, hidden w/in QRS, after QRS
Cardiac artifacts:
Causes of artifacts:
= hard to decipher iso-electrical lines w/ 0 & skewed
= M. tremors/shivering, PT mnt(moves baseline), Loose electrodes, 60-hertz interference(ungrounded electricity near you (AC current alternating in house), Machine malfunction (Dotted flat line),& electrode bad connection/ off
Intranodal/Mobitz 2) Sir name
2nd-Degree Type 2 AV block
Lown-Ganong) definer:
Pathway name & path:
= has short PRI interval
= Bundle of James connects posterior internodal pathway to bundle of his
only condition A-Fib has cadence:
Afib w/ 3rd degree In rhythm “Gandalf dead so Atriums & Ventricles doing own thing
Re-entry loops
= stuck in nascar loop in a chambers pathway causing SVT / no P waves
Sick Sinus Syndrome
Not arrhythmia per se; combination of arrhythmias; sinus node diseased or ischemic. Wild swings in HR, Ischemia of SA node,
Sinus Block)
“Block be in cadence” 1 or more dropped beats IN CADENCE “Gandolf Blocks a beat/s”
Systematic approach
- rate, 2. rhythm, 3. P waves, 4. PRI, 5. QRS
WPW) Orthodromic loop;
Antidromic loop:
Treatmeats:
= Clockwise reentry w/ narrow complex
= Counterclockwise reentry w/ wide QRS
= procainamide 1a Na blocker, (if no procain) sedate & cardiovert) cardioversion

Lown-Ganong
Bundle of James connects posterior internodal pathway to bundle of his (short PRI)
Mahaim
Accessory connects to Below bundle of his (wide QRS) looks like VTach

blocks in AV node partial or complete
