Arterial pulse waveform is composed of percussion wave travelling along artery which is at a much higher speed than the actual passage of blood with a dicrotic notch which represents the closure of the aortic valve.
| High output e.g. post exercise, thyrotoxicosis, fever, Hyperdynamic circulation, severe Paget's disease
| Aortic regurgitation or AV fistula. Low diastolic pressure. Wide pulse pressure.
|Slow rising small "pulsus parvus" seen with Aortic stenosis. Narrow pulse pressure.
| Hypertrophic obstructive cardiomyopathy
| Mixed collapsing and plateau pulse with mixed aortic valve disease
| Alternating large and small beats and suggests severe LV dysfunction
| caused by a premature beat before every QRS complex
| Normal BP fall with inspiration is exaggerated > 10 mmHg. Feel pulse weakens with inspiration. Consider Cardiac Tamponade, pericardial constriction and acute severe asthma where inspiration will affect cardiac filling. Pulse weakens during inspiration.
| dissection if aorta with ipsilateral subclavian involved, arterial thrombosis or embolism in subclavian or brachial or may be seen post catheterisation (angiography now done via radial artery), Takayasu's disease
| Suggests Coarctation of aorta. Be sure to check blood pressure at arm and legif suspicious.
