Answer: - anterior
◉ V5 and V6 look at what part of the heart
Answer: - lateral
◉ lead selection
Answer: - lead III is used to monitor patient who has no cardiac
history
- lead II to look at P waves
◉ precordial leads used
Answer: - V3 to monitor patient who has no cardiac history
, - V1 to monitor dysrhythmias and differentiate from ventricular
beats
- V1 to V6 if patient has injury or infarction....chooose lead that has
the most ST elevation
◉ for a normal ECG what leads do we pick
Answer: - Lead III and V3
◉ for ECG with dysrhythmia what leads do we pick
Answer: - lead III and V1
◉ ECG admission with AFIB with RVR what V lead do we choose
Answer: - V 1
◉ dysrhythmias that are too fast - affects
Answer: - heart cant fill completely
- decreases preload
- lead to decreased CO and low BP
- heart cant deliver O2 to tissues
