Which arteries unique in that they fill during diastole?
Coronary arteries unique in that they fill during diastole- when not squeezed by myocardial contraction.
In vasodilator washout effect –
Vasodilator washout effect – the vasoconstriction triggered by a decrease in the concentration of tissue metabolites
Bradykinin is broken down by all of the following kinases EXCEPT -
Bradykinin is broken down by three kininases:
- angiotensin-converting enzyme
- aminopeptidase P
- carboxypeptidase
Which of the following is called as - DEVIL'S GRIP
Bornholm disease is also known as -
Bamble disease
- the devil's grip,
- epidemic myalgia,
- epidemic pleurodynia
Bornholm disease- also known as epidemic pleurodynia - caused by mostly Coxsackie B virus
SA node artery mainly originates as a branch of -
SA node artery mainly originates from the right coronary artery
In classifying heart failure when the patient has marked limitation of physical activity. Comfortable at rest. Less than ordinary activity causes fatigue, palpitation, or dyspnea. Patient belongs to -
NYHA
CLASS -I - No limitation of physical activity.
CLASS -II - Slight limitation of physical activity.
CLASS -III- Marked limitation of physical activity.
CLASS -IV - Symptoms of heart failure at rest.
Orthostatic hypotension is a drop in systolic blood pressure of ------------- mmHg or more on standing from a sitting or lying position
Orthostatic hypotension is a drop in systolic blood pressure of 20 mmHg or more on standing from a sitting or lying position
Postprandial hypotension is a drop in systolic blood pressure of 20 mmHg or more or the systolic blood pressure drops from above 100 mmHg to under 90 mmHg within ------------ hours of eating.
Postprandial hypotension is a drop in systolic blood pressure of 20 mmHg or more or the systolic blood pressure drops from above 100 mmHg to under 90 mmHg within 2 hours of eating.
Mechanism - due to pooling of blood in the splanchnic vessels.
What percentage of subacute infective endocarditis develop clubbing?
10% of patients with subacute infective endocarditis develop clubbing
Hyponychial angle > ----------- is consistent with clubbing
Normal hyponychial angle is ≈160°, and an angle >180° is consistent with clubbing.
