Question 17

How to determine LVH

• Refer to lead___ and ___
• Select and measure the _____ of the 2 views
  
  • Measure from the isoelectric line down to the tip of the deepest QS complex and write that number down
• Now Refer to lead V___ and V__
• measure the tallest of the 2 QS waves
• measure from the isoelectric line to the tip of the Tallesta R waves and write it down.
• add the 2 numbrers together and if it adds up to be 35mm or more you would suspect Left ventrical Hypertrophy.

Answer 17

How to determine LVH

• Refer to lead V1** and **V2
• Select and measure the Deeper of the 2 views
  
  • Measure from the isoelectric line down to the tip of the deepest QS complex and write that number down
• Now Refer to lead V5** and **V6
• measure the tallest of the 2 QS waves
• measure from the isoelectric line to the tip of the Tallest R waves and write it down.
• Add the 2 numbrers together and if it adds up to be 35mm or more you would suspect Left ventrical Hypertrophy.
