Arrythmias Flashcards
What is the most common cause of a pause, missed complex or block on an EKG
PAC
premature atrial complex
non-conductive
what is the most common cause of block on any EDG and population
non-conductive PAC
explain p wave in premature atrial complexes
p wave abnormal
- premature to P-P interval
QRS in PAC
normal
etiologies of PAC
stress
smoking
caffeine
P wave in atrial fibrillation
P waves are absent
what leads do you look at for atrial fibrillation
V1 V2 II III aVF
ventricular rhythm for atrial fibrillation? rate without treatment
irregularly irregular
100-180
base line of atrial fibrillation
no baseline
biggest cause of atrial fibrillation
hypertension
define atrial flutter
rapid regular atrial undulations at a rate of 240-340
what leads do you look at for atrial flutter
II
III
aVF
inverted flutter waves without an isoelectric baseline
if you see heart rate of 150 that seems to be stuck at 150 always think
atrial flutter
Multifocal atrial tachycardia, atrial rate
greater than 100
p waves fo MAC
3 different p waves
