the addition of a 3rd or a 4th heart sound; makes the rhythm sound like the cadence of a galloping horse
Define Inching
technique of moving the stethoscope incrementally across the precordium thru the auscultatory areas while listening to the heart sounds
Define Left Ventricular hypertrophy (LVH)
increase in thickness of myocardial wall that occurs when the heart pumps against chronic outflow obstruction (ex: aortic stenosis)
Define Midclavicular line (MCL)
imaginary vertical line bisecting the middle of the clavicle in each hemithorax
Define Mitral regurgitation
mitral insufficiency; incompetent mitral valve allows regurgitation of blood back into left atrium during systole
Define Mitral Stenosis
calcified mitral valve impedes forward flow of blood into left ventricle during diastole

Define Palpitation
uncomfortable awareness of rapid or irregular heart rate
Define Pericardial friction rub
high-pitched, scratchy extra-cardiac sound heart when the precordium is inflamed
Define Paradoxical splitting
opposite of a normal split S2, so that the split is heard in expiration, & in inspiration the sounds fuse to one sound
Define Physiologic splitting
normal variation in S2 heard as two separate components during inspiration
Define Precordium
area of the chest wall overlying the heart and great vessels
Define Pulmonic regurgitation
pulmonic insufficiency; backflow of blood through incompetent pulmonic valve into the right ventricle
Define Pulmonic stenosis
calcification of pulmonic valve that restricts forward flow of blood during systole
Define Pulmonic Valve
right semilunar valve separating the right ventricle & pulmonary artery
Define 2nd Heart Sound (S2)
occurs with closure of the semilunar valves, aortic & pulmonic; signals the end of systole
Define Summation gallop
abnormal mid-diastolic heart sound heard when both the pathologic S3 & S4, are present
Define Syncope
temporary loss of consciousness due to decreased cerebral blood flow (fainting); caused by ventricular asystole, pronounced bradycardia, or ventricular fibrillation
Define Systole
the heart’s pumping phase
Define Tachycardia
rapid heart rate, >95 bpm in the adult
Define 3rd Heart Sound (S3)
soft, low-pitched ventricular filling soun that occurs in early diastole (S3 gallop) and may be an early sign of heart failure
Define Thrill
palpable vibration on the chest wall accompanying severe heart murmur
Define Tricuspid Valve
right atrioventricular valve separating the right atrium and ventricle
What are the major landmarks associated with heart & neck vessels?
- precordium

- apex
What is the Precordium?
area on anterior chest overlying the heart & great vessels
What is the mediastinum & when is it located?
midthoracic cavity that contains the heart & great vessels; located: 2nd to 5th ICS, right sternal border to left (MCL)
Where is the Apex of the heart located?

The leaflets of the tricuspid and mitral valves are anchored by __________________ to the _________________, which are embedded in the ventricular floor.

The ability of the heart to contract independently of any signals or stimulation is due to:
automaticity
