arterial pulse Flashcards
pulse deficit
heat rate-pulse rate Atrial fibrillation:cause
rhythm
regularly regular regularly irregular: sinus arrhythmia, pulsus bigeminus, pulsus trigeminus, A-V blockage irregularly irregular: complete heart block, atrial fibrillation (frequent extra systole)
pulsus parvus
low volume pulse hypovolemia, shock, acute MI,congestive pericarditis CHF, any stenosis
Hyperkinetic pulse
Regurgitation , VSD, PDA, anemia, thyrotoxicosis, fever,
pulsus parvus et tardus
decreased amplitude, low volume pulse, slow rising
contatins a palpable notch
water hammers pulse
collapsing pulse. rapid rise/rapid fall in pulse pressure
high volume
collapsing is due to dialotic leak back into left ventricle. rapid run off into perifery, low vascular resistance
water hammers pulse causes
AR, PDA, MR,
dicrotic pulse
2 peaks are seen in the pulse way, one in systole, one in diastole
low cardiac output and high systemic vascular resistance
Pulsus bigeminus
indicates a pair of hoofbeats within each heartbeat. Concurrent auscultation of the heart may reveal a gallop rhythm of the native heartbeat
regular alteration of pulse pressure amplitude. caused by ventricular premature contraction that follows each normal beat.
AV block
pulsus bisferans
seen in patients with aortic valve diseases
increased pulse with double systolic peak
Concomintatnt AS,AR
AR
Pulsus alternans
beat to beat varibility in amplitute with normal rhythm,
Advance heart failure
toxic myocarditis
following premature beat
paroxyomal tachycardia
Pulsus paradoxus
When the drop is more than 10 mmHg during inspiration.
Cardiac tamponade, chronic sleep apnea, croup, Asthma, COPD
conditions causing radio femoral delay
Thoracic inlet syndrome
Pre-subclavlan coarctation.
Supravalvular aortic stenosis.
Pulseless disease (Takayasu’s disease)
