Cardiac Lift
VENTRICULAR IMPULSEs |
accociated w/ rt venticular hytrophy b/c it pushes the heart. in the lower sternal border. may see retraction of the apex. lifts during systole.
|
|
|
Cardiac Thrill
|
can be palpated.
@ PMI. indicates severe aortic stenosis and hypertension. palapate over 2 & 3rd intercostal. common w/ patient lying supine, but roll to left side, and it will be more prominent. heart rubs against ribcage.) not palated until cardiomegaly. |
|
|
MURMURs S1
|
sounds likeS1 =Swish stub
SYSTOLIC atria is contracting. Tricuspid and Mitral valve. |
|
|
Diastolic S2
|
aortic or pulmonary valve causing murmur.= Lub Swish
|
|
|
Vessels bringing blood to the heart
|
Superior & Inferior Vena Cava
Rt & Left Pulmonary veins |
|
|
Vessels moving blood away from the heart
|
Pulmonary trunk
ascending aorta |
|
|
Tricuspid & Mitral Valves
(atrioventricular) |
lie betw. atria & ventricles
|
|
|
Semilunar valves
Pulmonic and aortic |
lower in the heart, have 3 flaps
|
|
|
Blood flow
|
Right Atrium
Tricuspud Right Ventricle Pulmonary valve pulmonary artery Lung |
|
|
Blood flow from the lung
|
lung
pulmonary veins left atrium itral valve left ventricle aortic valve aorta systemic circulation |
|
|
Pulmonary veins
|
bring O2 rich blood from lungs to the heart.
|
|
|
Pulmonary Artery
|
leaves the heart and brings to the lung.
|
|
|
SA NODE
(pacemaker) |
brings conduction to the AV nodes, then to the bundle of his, then to the purjinke fibers.
|
|
|
P WAVE = Atrial depolarization;
|
conduction on the impulse throughout the atria.
|
|
|
QRS COMPLEX
Ventricular depolarization (also called atrial repolarization). |
conduction of the impulse throughout the ventricles, which triggers contraction;measures from the beginning of the q wave to the end of the S wave
|
|
|
T Wave
Ventricular repolarization |
the ventrical returns to a resting state.
|
|
|
Heart Sounds S1
|
associated with systole
(the filling phase) pressure is higher in atria. |
|
|
Heart Sounds S2, S3, S4
|
associated w/ diastole
|
|
|
Cardiac output
|
amount of blood pumped by ventricles in 1 minute. SV x HR = CO
NORMAL is 5-6 L/min |
|
|

|
ECG,
ask another nurse to listen go to med records to see if there is a history |
|
|
# 1 THING TO MAKE A MURMUR WORSEN =
|
increase in blood volume from pregnancy, too much IV fluid, hypertension, possibly different types of HF
|

|
|
How to auscultate
|
position yourself on clients RT side.
client shoud be supine w/ upper trunk elevated 30 degrees Use diaphragm for all areas of pericardium hi pitched sounds with pressure. Bell is for low pitch sounds or gallups (lite pressure). |
