Why does Pulsus Bisferiens cause aortic stenosis?
Pulsus bisferiens, also known as biphasic pulse, is an aortic waveform with two peaks per cardiac cycle, a small one followed by a strong and broad one. It is a sign of problems with the aorta, including aortic stenosis and aortic regurgitation, as well as hypertrophic cardiomyopathy causing subaortic stenosis.
How do you detect Pulsus Bisferiens?
Pulsus bisferiens can be more pronounced by the Valsalva maneuver. On palpation of a peripheral pulse (radial artery), two upstrokes distinguished by a mid-systolic gap in the systole are characteristic of pulsus bisferiens. Jugular venous pressure (JVP) examination may reveal classical ‘a’ wave in HOCM.
What does arterial stiffness mean?
Arterial stiffness describes the rigidity of the arterial wall. In the last decade, there has been increasing interest in the potential role of arterial stiffening in the development of cardiovascular disease in adults.
What is the mechanism of Pulsus Paradoxus?
Mechanism. During inspiration, the negative intra-thoracic pressure results in an increased right venous return, filling the right atrium more than during an exhalation. The increased blood volume dilates the right atrium, reducing the compliance of the left atrium due to their shared septum.
Why does aortic stenosis cause narrow pulse pressure?
In aortic stenosis, there is a narrowing of the aortic valve, which interferes with the ejection of blood from the left ventricle into the aorta, which results in a decrease in stroke volume and a subsequent decrease in pulse pressure.
How do you measure water hammer pulse?
To feel a water hammer pulse: with the patient reclining, the examiner raises the patient’s arm vertically upwards. The examiner grasps the muscular part of the patient’s forearm. A water hammer pulse is felt as a tapping impulse that is transmitted through the bulk of the muscles.
What is Pulsus Paradoxus?
Pulsus paradoxus is defined as a fall of systolic blood pressure of >10 mmHg during the inspiratory phase.
Is arterial stiffness bad?
Arterial stiffness is a growing epidemic associated with increased risk of cardiovascular events, dementia, and death. Decreased compliance of the central vasculature alters arterial pressure and flow dynamics and impacts cardiac performance and coronary perfusion.
Is arterial stiffness harmful?
Background— Arterial stiffness has been associated with the risk of cardiovascular disease in selected groups of patients.
What does a Dicrotic pulse mean?
Abstract. The dicrotic pulse is an abnormal carotid pulse found in conjunction with certain conditions characterised by low cardiac output. It is distinguished by two palpable pulsations, the second of which is diastolic and immediately follows the second heart sound.

What do you need to know about pulmonary vascular disease?
Pulmonary vascular disease is the medical term for disease affecting the blood vessels leading to or from the lungs. Most forms of pulmonary vascular disease cause shortness of breath. The definition of pulmonary vascular disease is simple: any condition that affects the blood vessels along the route between the heart and lungs.
How does peripheral artery disease affect your limbs?
Claudication Peripheral artery disease (also called peripheral arterial disease) is a common circulatory problem in which narrowed arteries reduce blood flow to your limbs. When you develop peripheral artery disease (PAD), your legs or arms — usually your legs — don’t receive enough blood flow to keep up with demand.
What causes blockage in the large arteries of the heart?
This buildup can partially or totally block blood flow in the large arteries of the heart. Some types of this condition may be caused by disease or injury affecting how the arteries work in the heart. Coronary microvascular disease is another type of ischemic heart disease.
What causes plaque in the wall of the heart?
Plaque is made up of cholesterol deposits. Plaque buildup causes the inside of the arteries to narrow over time. This process is called atherosclerosis. Coronary artery disease is caused by plaque buildup in the wall of the arteries that supply blood to the heart (called coronary arteries). Plaque is made up of cholesterol deposits.
