CRAT
PAT (paroxysmal atrial tachycardia)
PVT (polymorphic VT)
3 PVCs in a row
VR
Regular rhythm, no p-waves, wide QRS, hr less than or equal to 40 bpm
IR
the first aberrancy vs ventricular beats question
Are there p-waves? Yes (aberrancy) No (ventricular)
WAP at HR over 100 BPM
MAT (multifocal atrial tachycardia)
rate of 150bpm, narrow QRS, no p-waves, seen for entire strip
SVT
type of premature beat in which the regularity of the rhythm is not interrupted
IP
regular rhythm, no p-waves, wide QRS, hr 41-100 bpm
AIR
the second aberrancy vs ventricular beat question?
Is there a delay. Aberrancy (non comp). Ventricular (comp and non comp)
type of EAR when both rhythms are tachycardic
EAT (Ectopic Atrial Tachycardia)
125 bpm, inverted retrograde p-waves seen on some of the beats
SVT
if both the SA and AV node fail a site at or near the B of H might fire an ectopic beat known as a
VEB
4 or more pvcs in a row at a rate of 120 bpm
VT
the third aberrancy vs ventricular question
Is there deflection change? Aberrancy (no). Ventricular (yes)
normal chart speed setting for a standard 12 lead ecg machine
25 mm/s
type of ectopic tachycardia with starts or stops suddenly
PSVT
single pvcs with at least 2 different QRS complex morphologies
Multifocal PVCS
TDP
The difference between VS and AS
VS has mapping p-waves for greater than or equal to 6 seconds with no returning beat and AS is a flat line for 6 seconds with no returning beat
a "widow maker" MI is associated with a block in this coronary artery
LCA
VT always has inverted t waves
false
early beat, wide QRS (underlying rhythm has narrow QRS complexes), ectopic p-wave is seen
aberrant pac
no identificable ECG waveforms
VF
name all potentially underlying tachycardic rhythms (6)
