Best leads to see wide QRS complex tachycardia?
V1 (second best is V6)
In both, VTs & SVTs can best be distinguished from each other. Additionally, in V1 RBBB is easier seen than in V6
What leads view the lateral heart?
Lead 1, AVL, V5, V6
What leads view the inferior heart?
Leads 11, 111 & AVF
What leads view the RV?
Right sided chhest leads (V1 & V2)
What leads view the posterior heart?
Electrodes placed on back - V7
What is acute coronary syndrome (ACS)?
USA, NSTEMI, STEMI
How long should pts (ACS) be monitored for ST changes?
24-48hrs or until event free for 12-24hrs
What two periods are important for ST monitoring in pts with acute STEMI
First 6hrs after therapy (thrombolytics or primary angioplasty)
The period 6-48hrs after therapy
How long should ST monitoring be done for pts with CP in the ER
8-12hrs after in combination with monitoring of cardiac biochemical markers
How long should ST monitoring be done for pts who have had catheter based interventions?
Initiate ST monitoring in cath lab to determine ST fingerprint (pt's unique pattern of elevation/depression based on anatomic site of coronary occlusion)
When is ST segment monitoring not recommended in a pt with EKG changes?
Pts with LBBB, intermittent right or left BBB, venticular pacing rhythm, or excessive noisiness due to restlessness or confusion
Best lead to detect RCA occlusion & ischemia of inferior wall?
Lead 111, next best is AVF then lead 11
Best lead to detect LAD occlusion?
V2 & V3
Less often V4
True or false
Occlusion of any coronary artery alway produce ST changes?
False
In 30% of the population, occlusion to the left circ produces no changes
Best lead to detect Left Circ occlusion affect lateral heart?
V5 or V6
