Front 1

5 categories of IHD

Back 1

stable angina pectoris
unstable angina pectoris
non-ST-segment elevation myocardial infarction
ST-segment elevation myocardial infarction
ischemic cardiomyopathy

Front 2

ECG findings with an MI

Back 2

1) hyper acute T waves
2) ST-segment elevation or depression
3) pathologic Q waves
4) T wave inversion

Front 3

using troponin levels to distinguish angina from MI

Back 3

normal: unstable angina
elevated: MI

Front 4

using S-T interval to distinguish MIs

Back 4

elevated: STEMI

Front 5

what does a positive P wave tell you

Back 5

guarentees that the pt is not in sinus rhythm

Front 6

net voltage in QRS:

Back 6

difference b/w positive deflection (r) and negative deflection (q if it proceeds it, the s wave if it follows it)

Front 7

a fib is characterized by

Back 7

absence of discernable P wave
irregularly irregular rhythm

Front 8

a fib is risk factor for

Back 8

stroke

antiCoAg for life

Front 9

v tach can be defined as

Back 9

three or more consecutive VPCs

Front 10

vfib is characterized by

Back 10

irregular deflections of variable amplitude and contour

absence of P QRS and T wave

Front 11

2nd degree AV block

Back 11

some P waves are conducted to ventricles

produce a QRS complex and some are not

Front 12

3rd degree AV block

Back 12

none of the P waves are conducted to ventricles

subsidiary pacemaker somewhere belwo the bundle of his becomes the pacemaker for the ventricles

Front 13

a pt is in sinus rhythm when...

Back 13

1) every P wave is followed by QRS
2) every QRS is preceded by P wave
3) every P is positive in lead II and negative in aVR
4) in any one lead, the P waves are identical

Front 14

characteristic features of APCs

Back 14

-early arrival
-abnormal and sometimes inverted P wave
-normal QRS, T
-post-APC cycle is not fully compensated

Front 15

characteristic features of VPCs

Back 15

1) bizarre QRS complex with prolonged QRS interval
2) ST segment sloping in the direction opposite to the QRS complex and leading into a T wave also in opposite direction from QRS
-post-VPC is compensatory

Front 16

torsade de pointes

Back 16

polymorphic v tach that is associated with a prolonged Qtc interval, when in sinus rhythm

Front 17

1st degree AV block

Back 17

all P waves are followed by a QRS, but PR interval is prolonged

Front 18

ECG hallmark of BBBs


why?

Back 18

prolonged QRS interval in all QRS complexes

due to the fact the in BBB th ventricles depol one after the other, rather than simultaneously

Front 19

how to determine if its R or L BBB

Back 19

using the latter part of the prolonged QRS complex
