healthy heart has a sinus rhythm .
Where the SA node triggers cardiac activation
INDICES OF A SINUS RHYTHM : 1. .
(Hive P wave in lead #I
2) We P Wave in AvR lead
2 .
every lead has constant form of P-wave
.
3 constant P-O interval
4 .
P wave appears before the ORS complex /most important feature)
2 HEART RATE

⑤ MEASURE THE CRS AXIS the axis is the general direction of electrical impulse through
the heart .
the concept of an axis denotes the net electical impulse recture
. This is normally shown in a
rectorcardiograph as a function of time.
