What is a vector in the heart? - Answer-The purpose of
electrocardiographic investigation is to find out something
about the heart itself by means of an accurate knowledge
of its electric action. This may be repre- sented by the so-
called heart-vector, a directed quantity, indicating in which
direction elec- tricity is propagated by the heart.
Left Axis Deviation (LAD) - Answer-30-90 degrees
Right Axis Deviation (RAD) - Answer-+90 to +180
normal axis - Answer--30 to +90
Extreme Axis Deviation - Answer--90, 180
normal axis qrs in v1 & v2 - Answer-pos / pos (thumbs up /
thumbs up)
,2|Page
LAD qrs in v1 & v2 - Answer-pos / neg (thumb up / thumb
down)
RAD qrs in v1 & AvF - Answer-neg / pos (thumb down /
thumb up)
North West Axis (extreme) qrs in v1 & avF - Answer-neg /
neg (thumb down / thumb down)
two parts of left bb - Answer-left anterior fascicle & Left
posterior fascicle
right ventricular hypertrophy signs + right axis deviation = -
Answer-likelihood of right axis deviation
LVH on an ecg - Answer-sum of S wave in v1 + v2 and the
R wave in v5 or v6 is greater than or equal to >35mm
if pt has LVH (s wave + R wave = >35mm), and pt has
RAD (neg/ pos) + - Answer-Biventricular Hypertrophy

deflection of a impulse toward a lead - Answer-positive
deflection of an impulse moving away from lead - Answer-
negative
deflection of an impulse moving 90 deg to a lead - Answer-
same pos/neg deflection (equiphasic)
easy 7 steps to finding axis on ecg - Answer-1. find the
most equiphasic limb lead
2. look at lead running 90 deg to this
3. impulse mainly +Ve? axis is towards this lead
4. impulse mainly -Ve? axis is away from this lead
5. truly equiphasic? yes- you found cardiac axis
6. slightly more +Ve ; move axis 15 deg towards
equiphasic lead
7. Slightly more -Ve? Move axis 15 deg away from
equiphasic lead
right ventricular hypertrophy (causes) - Answer--
pulmonary hypertension
-mitral stenosis
, 4|Page
-pulmonary embolism
-chronic lung disease
-congenital heart disease
right ventricular hypertrophy (leads) - Answer-- right axis
deviation
- dominant R wave in V1 (>7mm tall or R/S ratio >1)
- dominant S wave in V5 or V6 (>7mm deep or R/S ratio
<1)
-QRS duration <120ms (changes not due to rbbb)
Right Atrial Hypertrophy (causes) - Answer-- chronic lung
disease
- tricuspid stenosis
-congenital heart disease
- primary pulmonary hypertension
-anything that increase size in cell size
Right Atrial Hypertrophy (leads) - Answer-- p wave is
>2.5mm in the inferior leads (II,III, avF)
->1.5mm in V1&V2
