This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Miscellaneous, Subject name: Medicine
All of the following are true about pulsus parvus EXCEPT 
Select and explain. 
A. Seen in aortic stenosis, B. Decreased left ventricular output, C. Decreased peripheral resistance, D. Decreased pulse pressure
C: Decreased peripheral resistance
Answer: C: Decreased peripheral resistance 
Explanation: (C) Decreased peripheral resistance ABNORMAL PULSES# Collapsing or Bounding Pulse:# Pulsus celer or water hammer or Corrigan pulse Aortic incompetence PDA and VSD Complete heart block High cardiac output states Hyperkinetic circulation Marked vasodilatation> Anacrotic Pulse: Aortic stenosis> Plateau Pulse: Aortic stenosis> Pulsus Bisferiens: Double systolic pulsation Severe AR with mild As Pure AR Idiopathic hypertrophic sub AS> Dicrotic Pulse: Debilitating fevers Dehydration Advanced myocardial failure Cardiac tamponade Following open heart surgery> Pulses Parvus: Small volume. Weak upstroke due to decreased stroke volume. Physiological -- Vasoconstriction from cold or anxiety Partial occlusion of vessel Coarctation of aorta AS or MS Severe hypotension (Hypovolemia) Myocardial infarction P. S. (severe grade) Severe pulmonary hypertension> Pulsus Parvus et Tardus: Severe AS> Pulsus alternans : Regular alteration in pressure amplitude LVF, Cardiac arrhythmias Toxic myocarditis> Pulsus Bigem in us: Coupling. Alternate premature beat AV block Digitalis toxicity Sinoatrial block with ventricular escape> Pulsus Paradoxus: Exaggerated inspiratory fall in systolic BP Cardiac causes: Constrictive pericarditis, Cardiac tamponade, Acute LVF Respiratory causes: Obstructive lung disease, Tracheal obstruction, Asthma, Emphysema Others; SVC obstruction, Obesity, Hypovolaemic shock Unilateral pulsus paradoxus is due to compression of one anomalous subclavian artery. Reversed pulsus paradoxus : expiratory fall in BP is seen in- Hypertrophic obstructive cardiomyopathy- Intermittent positive pressure ventilation- Isometric ventricular rhythm
