Poor R wave progression refers to the absence of the normal increase in size of the R wave in the precordial leads when advancing from lead V1 to V6. In lead V1, the R wave should be small. The R ...

Sokolow-Lyon Criteria: Add the S wave in V1 plus the R wave in V5 or V6. If the sum is greater than 35 mm, LVH is present. Romhilt-Estes LVH Point Score System: If the score equals 4, LVH is ...

A P wave occurs before each QRS complex (+) with a stable PR interval (0.20 sec). The P waves are positive in leads I, II, aVF, and V4-V6. This is a normal sinus rhythm.

With this reading, the waves on the ECG are equal in size and shape, predictable, and regular. With normal sinus rhythm, your heart rate should be between 60 and 100 beats per minute.

This presents with initial small Q waves in leads I, aVL, and V5-V6 and a septal R wave in lead V1. With an LBBB, septal forces are not seen because the septal or median branch that innervates the ...

The EKG gives two types of information, according to the AHA. First, it records how long it takes a wave to travel from one part of the heart to the next, showing if electrical activity is normal ...
