ECG Flashcards
which heart sound is heard in early diastole
S3
which heart sound is heard in late diastole
S4
S3 heart sounds are associated with what diagnosis
CHF
can be seen with athletes and pregnant woman
aka ventricular gallop
(
what is associated with s4 heart sounds (diagnosis)
HTN
pulmonary HTN
MI
L ventricular hypertrophy
L ventricular end diastolic pressure
pulmonary stensis
P waves means what
atrial depolarization
QRS complex means what
ventricular depolariztion and atrial repolariztion
T waves means what
ventricular repolariztion
When would you call 911 when working with a patient
regardining cardiovascular
3rd degree AV block
more than 2-4 couplets/min
3+ PVC in a row
V tach
V fib
ST depression > 2mm
ST elevation > 1mm
multifocal PVC
1st degee AV block
PR interval is greater than 1 large box (>0.2 sec)
seen in athletes with increased vagal tone (activity)
generally wont progress, benign condition
2nd degree block, type 1
PR interval is increasingly getting larger and a drop occurs.
when do you stop an exercise and refer (not immediate)
1 couplet (2 consequative PVCs together with no normal beat between them)
2 degree block type 2
A Fib
symptomatic A flutter
2nd degree block, type 2
PR intervals are constant and a QRS is dropped
unexpected
no pattern
3rd degree AV block
no symmetry/relationship
the atrial rate is independent of ventricular rate
emergency
what to do if you notive a first degree AV block
exercise wise
continue exercise
what do you do when you notice a 2nd degree block, type 1 during exercise
monitor and continue with lower intensity
